Hier stimmen die Modbus Functiosn nicht. Leider sind viele Hersteller der Meinung solche Details aus ihrer Dokue weglassen zu können… |
|
Also prinzipiell lädt das Auto und ich kann zwischen allen Modi wechseln |
|
Fertig. Siehe #3103 |
|
habe es schon beobachtet. Kommt mit dem nächsten Update? Dann kann das Thema hier geschlossen werden. Danke! |
|
@robhei89 Könntest du bitte noch die Info posten wie die Freischaltung funktioniert hat oder wo man sich melden müsste dafür? Finde dazu nichst im Netz außer einen User der sagt dass für private User Modbus+OCPP geperrt sei. Danke! |
|
erstmal versuchen über den Browser auf die Box zuzugreifen. Login: |
|
Und dann beim Punkt Lastmanagement auf "Open Modbus..." umstellen |
|
Top, danke! |
|
Fehlt uns da noch ein Stück Doku? /cc @premultiply |
|
Hello, Login: operator Gibt es ein anderes Passwort das funktionieren könnte? Vielen Dank und Grüße |
|
Habe eine Lösung gefunden. |
|
Hi, |
|
Ist der Juice Charger Me zu Empfehlen für EVCC? Sehe ich das richtig, dass die RJ45 Buchse unten frei zugänglich ist und man das Kabel einfach abstecken kann? |
|
Also: Ich habe den Support ausgiebig genervt. Ergebnis war: verkauf der Wallbox und kauf einer cfos Wallbox. Einfach mal durch die Anhänge durcharbeiten. 1 Bildschirmfoto.pdf |
|
Warum genau muss es ein MID Zähler sein? Normaler mit separater Kommunikation tut es nicht? Sollte mit evcc ja darstellbar sein |
|
Ich habe mir auch die Juice Charger me relativ günstig gekauft. => Ich schätze ich habe auch keinen MID. |
|
Klasse, vielen Dank! Das hilf mir sehr weiter. Ich denke nicht, dass das nur der Juice Support kann. Es ist ja keine große Sache das root Passwort des Ladereglers rauszufinden, die Box schreibt das ja großzügiger Weise in die Config Files (Stichwort ZIP-Passwort) beim dumpen der Config und logs auf einen USB Stick. Dann kann man vermutlich auch alles selbst einstellen. Komischer Weise geht das root Passwort zwar zum Login per SSH auf der CC613 aber nicht als manufacturer in der Web-Oberfläche. Ich muss noch rausfinden warum. Das Menü für den Zähler wurde ja leider im operator Modus ausgeblendet, aber das geht mit Sicherheit in irgendeinem Config File oder einem SSH Befehl. Ich lasse Euch es wissen, sobald ich das rausgefunden habe. Ach ja: Alle die keine Elektrofachkraft oder was nahe dran sind und wissen was sie da tun lassen das bitte sein!!!!! Wir wollen nicht, dass ihr Euch oder andere gefährdet. Bitte. Danke. Dass nach so einer Aktion die Garantie weg ist, ist klar - aber die Hardware de ME ist einfach fantastisch, der CC613 ist ein großartiger Regler und auch alles andere in der Box ist hochwertiges Material. Das Risiko ist also recht klein und wer einen Zähler einbauen kann, kann zur Not auch selbst richten.... Die Wallbox gibt es ohne Zähler aktuell bei energieloesung.de für 379 €. Den Zähler im Netz für 190 €. Das ist es mir wert, das jetzt einfach mal zu testen. Der CC613 alleine kostet ja schon mehr, wenn man ihn einzeln kauft. @b2222 --> Nein, dafür brauchst Du keinen MID Zähler. Einen Zähler brauchst Du nur, wenn Du abrechnen möchtest, nicht zur PV-Steuerung, denn die PV Steuerung macht am Ende der Laderegler zusammen mit dem Auto (Du musst eh am Ende dem Auto vertrauen, dass es nur soviel Strom zieht, wie der Regler vorgibt, aber das ist in der Praxis schon sehr zuverlässig). In meinem Fall möchte ich die Ladestation halb-öffentlich betreiben und dazu brauchst Du einen MID Zähler. Streng genommen muss sie eigentlich sogar Eichrechtkonform sein, das geht mit dem CC613 auch, aber ich hab dazu noch keine Doku gefunden. Mit dem von Juice vorgeschlagenen Zähler geht es aber nicht, man müsste einen anderen nehmen, der ist aber zu große und muss dann aber in ein externes Gehäuse, das einsehbar ist (wegen dem Public Key und dem Display), das sieht doof aus und dann musst man noch ganz viele Sigel kleben... Außerdem ist das vermutlich am Ende auch viel zu teuer. Viele Grüße, |
|
Naja so großartig sind die Controller jetzt auch nicht. Und der Rest ist leider auch schon ziemlich angestaubt. Diese Controller sind halt überall drin wo Firmen ohne echtes Entwickler-Knowhow in dem Bereich Wallboxen anbieten möchten. Schön wäre wenn Bender zumindest auch die unveränderte Originalfirmware veröffentlichen würde damit man eine Chance hat zumindest halbwegs aktuelle Software zu installieren. |
|
@robhei89 danke fuer seine foto. Kennst du mir bitte sagen, was fuer eine energie messunggeraet ist dort? Genaue Kennzeichnung oder Foto des Etiketts bitte. Ich weiß, es kann sein ein Carlo Gavazzi EM340...? ich also finde liste_der_kompatiblen_zaehler |
|
Hi, es ist ein EM340DINAV23XS1PFB oder ein EM340DINAV23XS1PFA sollten beide gehen. Der Unterschied ist nur, dass einer beide Richtungen zählen kann, der andere nicht. Aber den A Typ bekommt man nirgends. |
|
It is now officially supported, and I can confirm the JCME / CC613 charger works together with meter Carlo Gawazzi EM540 via Modbus. All values read, also with serial number. My one was bought as "Victron sortiment" item: EM540DINAV23XS1X29 |
|
Moin, der Juice Charger Me müsste doch über die evcc configure (nicht advance) direkt funktionieren, oder? Irgendwie steuert er aber nichts. |
|
@mreschka schon Neuigkeiten zum manufacturer oder zip Passwort? |
|
@Jordan87 I sent my manufacturer pw to you. |
|
Thanks a lot, you password was correct for manufacturer but it seems I just cleaned all setting with "Factory Reset & Reset", currently no Juice configuration on Bender module and i errors i see "Type 2 actuator stuck, cannot unlock" and all three leds are blinking :/ If somebody can share config from Operator and Manufacturer tab this could be useful for me. |
|
@Jordan87 as posted somewhere else in this thread, the screenshots: |
|
could you also share the Password with me? I believe i broke my Juice Charger me (1.st Gen) with the new Bender SW. |
|
try this one: GHYUTep6KHXaA9NV2 |
|
Hello, I just bought this charger for cheap as well. The EASTRON SDM72D-M-2-MID meter is only € 52 and should be supported as well. Or the EASTRON SDM120 for € 30 if you only need one phase. Haven't yet checked if these fit in the box. |
|
I can confirm that EASTRON SDM72D-M works with Juice Charger me. I used the empty slot in the upper area of the wallbox to install the meter: I used 6 mm² cables to connect it to the connection box on the left side of the wallbox. Having failed several times I finally got this setup to work. connections:SDM72D-M MODBUS A -> Bender CC613 MODBUS A I used telephone cable to connect the meter to the charge controller (Bender CC613). meter configuration:Meter slave ID: 1 Please see manual for details: wallbox configuration (sorry, got this only in German):

My wiring:
Best regards, |
|
GND einfach weglassen. |
|
Thanks DFS-90! @premultiply, as far as I know RS485 does need a common ground, like most electrical components. It's a two wire protocol where the ground is just assumed to be common; but that doesn't mean the ground doesn't exist. After all, the modbus meter has a ground terminal for a reason. If the Bender is grounded you should ground the modbus meter to the same ground. No matter if that's the PE terminal or any other ground in the box. (Unlike ethernet which uses transformers on both sides.) The RS485 protocol does have some margin for differences in ground potential, so it might just work without common ground. (Until it doesn't.) The external modbus connection on the Bender (terminal block I) does have 3 terminals, one for ground. Because the external meter might be on a distance, metering a system with a dedicated earth ground wire, so then you need to use the third wire to ground the external meter with the ground from the Bender. So it makes sense it has 3 terminals to connect a three wire modbus cable. |
|
I can cofirm that it didn't work without Ground in my case. |
|
I have ordered a connector for the external meter on terminal block I, because I want to use the load balancing feature. I hope I identified the right connector: |
|
I haven't succeeded in getting an external load meter to work. I have connected an Eastron SDM 120 meter (single phase setup) to the I terminalblock. I programmed the Eastron for address 2, 9600 bauds, no parity and 1 stop bit. But the Bender keeps saying it's getting no data. I also connected an RS485 USB adapter to the I terminal block, to monitor the data, but I got no reading. I expected the Bender to request values from the external meter, but it is not requesting anything.. |
|
off topic: Try it on your own risk: |
|
My Fiat 500e hasn't arrived yet, so I can't test. But it should support Autocharge according to the EV Database and Fastned. It probably doesn't support ISO 15118. |
|
I can confirm the Fiat 500e outputs a MAC address and the controllers picks up on it:
|
|
What is the output of |
|
It doesn't output much: Charge status: C |
|
Sorry, should have enabled outputing the UID. This now outputs this line (changed it a bit to obfuscate): Identifier: 001823218950 Which is the MAC address without the colons (:). |
|
I got an 'ALLNET ALL-WA0150N' wifi adapter, which should be supported according to the documentation, but it doesn't work. So I guess they ship that adapter with a different chip in it now. Had an old Belkin N300 high gain wifi adapter lying around which works fine, but the antenna doesn't fit in the box. So still searching for something. |
|
I can recommend any of the listed Realtek Chipsets, I bought sticks that are built with them.
In general, this list seems to be quite a good base: |
|
I can confirm a RTL-8192CU based wifi adapter works fine. My ALLNET ALL-WA0150N adapter based on the MediaTek MT7601UN doesn't work, eventhough it is on the list. |
|
I can confirm that, too. I ordered another Wifi adapter (BIGtec 150Mbit slim USB WLAN Mimo Wireless Stick) which is based on a Ralink RT3070 chipset. Works perfectly "out of the box". |
|
My RTL-8192CU based stick kept loosing the connection after a while. It would work for half a day or so and then fall of and not coming back without a reboot. I had an old tplink travel router laying around that fits in the box. It connects to the Ethernet of the controller and takes USB power, so no reliance on the Linux wifi drivers anymore. Has been stable and fast so far. |
|
My Wifi adapter (BIGtec 150Mbit slim USB WLAN Mimo Wireless Stick) which is based on a Ralink RT3070 chipset still works fine. No connection losses up to now. If your wallbox is mounted in a protected environment (e. g. garage), it might be a good idea to use a USB extension (for example this one) in order to improve wifi reception. |

Hi, I can confirm that the firmware 5.33.5-21148 is working well on my juice charger me. I have a question regarding DLM |
|
You can use the 12 volt adapter in your Juice Charger. It is already connected to the 12V and 0V connectors on the Bender. So you can split it from those wires/connectors. Next: connect the 12 volt source to the (+) pulse output of a power meter, like an Eastron SDM120. Connect the (-) pulse output of the power meter to the Opto+ connector on the Bender. Connect the Opto- connector on the Bender to the mass/negative of your 12 volt source. The Bender will measure the pulsating voltage differences between the Opto+ and Opto-. Note: the Bender assumes the Opto pulses measure the total power over three phases. It also assumes the power is split equally over the three phases. If you have a single phase system, the Bender will still think the measured power was measured over three phases. The calculated power for your single phase will therefore be three times lower than intended. To compensate, configure the 'Pulses per kWh (Second S0 meter)' setting on the Bender to be three times less than what the meter is configured for. For example Eastron meters by default will send 1000 pulses per kwh, so configure the Bender to 333 pulses per kwh. Or set the Eastron to 2000 and the Bender to 666. Set the 'External Meter Location' to reflect your situation. In my system, my power meter doesn't measure the power of the charger, only the rest of my house, so I've set it to the 'exclude' option.

Hello Dr.Fisheye thanks a lot for your support.
Ah I got it. That makes sense! But what I do not get is the rest of what you wrote. First of all I just want to realize the Load throw off from the grid supplier, because I have to do by legal.
What you explained (the measuring of Load via Pulsing) is for the use of DLM like evcc, isn´t it? |
|
I can send you the complete pictured wiring diagram of my JCME3 charger with dry contact. I plan to re-wire my old JCME without it. Please give my few days. I guess it should be as simple as connect +12V trough dry contact (potential free switch) to Bender opto-in. And the -12V to the second contact of your opto-in. Using S1 signal impulsem you can give the charger an information About your (house?) overall energy consumption (that should influence the charging speed for to not overload your grid source limit - installed circuit breaker current). The second function (legally expected by responsible grid operators) is a "grid helping" contact. There should occure any rare case the grid ask you for help as if any device overload/insufficient energy production/other trouble. Practically: As soon as you physically disconnect the signal from Opto-in, it should automatically limit the charging speed to minimum (configured in Bender setting). That dry contact is usually a potential free relay contact. Such contactor is managed directly by grid operator. PS: let me know if I am not correct. |

Hi EVhonza,
a pictured wiring would be very helpful for me and maybe others.
Don´t hurry, I also need some days before I can start.
Thank you.

Hi again, so, it´s as easy as EVhonza and Dr Fishey stated: If you don´t want to spent the money for the bendeer connector kit, buy the Phoenix Contact 1790124 --> https://www.phoenixcontact.com/de-de/produkte/leiterplattenstecker-dfmc-15-4-st-35-1790124 much cheeper |
|
Hello guys, is this thread still alive? I really need your help here as i got this charger installed by an electrician and did not get any help as how to configure it. it is connected to single phase and i cannot increase the Amps settings from the default 16 to 32. I login with operator/JuiCeMeUP! and the connection is done with usb cable. |
This might be dangerous. Is your electric installation powerful enough to handle this current? Your electrician installed this charger with the 16A in mind... In which country are you? For example in Germany the single phase limit is 20A. It's because of unbalanced load or "Schieflast" |
|
To change the maximum current you need to login with the manufacturer account to the legacy site. http://192.168.123.123/legacy/manufacturer/manufacturer On the operator tabs there are also two current limit fields that you need to set to a higher value. Be sure that your cabling, home connection and other devices in the loop can handle the load. I've been using my charger on 26 A without problems. I have a 1x35A connection to my home and used 6mm2 wires to the charger. |
|
drfisheye you really saved me there. the link and password were correct. i managed to change the setting to 32A. now i will start digging further as i have a carlo gavazzi em340 for load management. if you can help me set it up i will be in your debt. |
|
Hello I also used the username and password and work to connect but still i cant change the A limit any help?? |
|
ok these are my results after experimenting little bit.i dont know if my settings are correct. Right now seems to be communication between the carlo gavazzi and the charger, and as i understand my settings (16A) are limitting the charging. am i correct ? find attached photos of my settings for your reference. |
|
ok now i found the proper setting and i see that actuallly the charger is not communicating with the em340. Tomorrow i will check the connections and settings on the em340 . Any help appreciated. More photos incoming: |
|
If you have the Juice Charger Me with the CC613_ELPR variant of the CC613 controller, then that doesn't support a modbus external meter for load balancing. It doesn't have the electronics to measure it. You could use the pulse output of the EM340, but since the EM340 is 3 phase and the pulse can only represent a single powervalue, it will probably measure the total power over all 3 phases. I'm using a pulse output myself, but it's connected to a single phase powermeter. |
|
drfisheye thanks again for the reply. Unfortunately i have the CC613_ELPR. so that means i need a meter like the sdm120 to use with the pulse output? |
|
Yes. The cheapest Eastron SDM120 variant with only a pulse output would do. There is also a variant with a pulse AND modbus (which I have). But that one needs configuration to output the right pulse, for which you need a modbus-usb adapter and software, which was a hassle! So the cheapest one is easier. Or like Fritzchen-66 says, a modusbus-over-ethernet meter, or converter, might work, but I have no experience with it. |
|
For an external meter, you have 2 possibilities: |
|
hello guys i finally got a hager ECP 180D with Pulse which is this onehttps://hager.com/uk/products/h/ecp180d-1ph-kwhmeter-direct-80a-2m-s0-mid. I need help with wiring the S0 pulse correctly since i can not get it to work properly. this meter has two s0 outputs and i know that i can use the existing 12v power source. i already have these connectors https://www.phoenixcontact.com/de-de/produkte/leiterplattenstecker-dfmc-15-4-st-35-1790124 thanks in advance and merry christmas and happy new year to everybody |
|
Good day please be informed that i managed to connect it with the following wiring in case anyone needs PSU +12V ─────────▶ OPTO IN + I will post later some screens from the readings on the web interface |
|
Okay here are some examples of my 1 phase system. I have adjusted my settings for the pulses to 333 (instead of 1000) as drfisheye suggested. I see that the charger does not calculate correctly the AMPs and KWs but does reduce the load when a heavy consumer comes in play. If i leave the setting at default 1000 pulses i get correct amp and kw readings(i presume as i dont have an ampere clamp) but the charger will not reduce the load if i switch on some heavy load. I guess that the system thinks that it can use current from the other phases that are not connected (single phase) example 1 (no load applied) any thoughts are really welcome |

Hi comunity. We have two new Vulnerabilities. The first one is reported here. The second is our forum itself, as some of skilled you, publically noted the normally hidden access to the management and let it here for public and internet robots. Consequence is simple: easily readable important (normally not public) informations can turnaround from help to vulnerability. Who of you can repair the unit with locked/unknown manufactrurer pw ...? Are you happy to send your device back in service for firmware flash/restoration? I do please the user: @drfisheye to edit their two posts and delete the two vulnerabilities here (sorry, this forum has no PM messages and admin do not acts). Any others to be so kind and do not disclose the comonly closed informations. Thank you a lot! Everyone who search well trough can well find extremely interresting informations... |
|
Hi https://drive.google.com/drive/folders/1XwV3eta32yRtbVjMGp9QypZwIFgULqDD Do we have changelog? |
No, you can not use the firmware from spelsberg. You need the firmware for the cc613 |
|
Hi @muewe, |
|
For my two JCme 1 I used the JCme3 update software provided by Juice. However, to link the SDM72 to your JCme WB, you may have to enter the installation web page of the Juice (not the operater page). How to do that is described here little further upstream. |
|
Hi @GRaptor, |
|
That’s the firmware I have installed on mine (not manually, was done automatically by the updater) |
|
Hi all, Now I see frequent logout from the local web UI, Acording to Juice support it shall not be used anymore, only the J+ app What I want to achive (with ID.BUZZ 2026) is
|
|
Hey muewe, any details how to fix logout issue using the update tool? I tried disconnection from internet but it didn't help, so the backend connection might not be the only cause. Which version of the dashboard do you have (Premium / Plus / Standard)? |
|
study information across this discussion forum |
Advanced Settings -> Uninstall and Cleanup |
|
In my case j+ integration was also casing local issue with Home Assistant connection |
|
I also noticed that with REST and local dashboard parallel access. It seems paralel sessions are not supported, so |
|
Hello again, Thanks in advace |
|
this is suitable for juice charger me 1 also? |
|
Yes, I have the JCME1 too. I am using it since a few months without any problems. With the 5.34.0 I had some problems with OCPP |
|
i installed successfully the update. unfortunately i still have the same problem. i can not start or stop the charging from home assistant. but i can change the maximum current value successfully |
|
Omg thank you so much you are right.. Feel so stupid. Fixed that part. Now am back to the previous part. I can toggle availability on and off while the cable is disconnected and I can not switch on the charger control. The problem is after I connect and start charging why I can not switch off the charge control? |
|
Maybe you have local whitelist on your charger with Autocharge? If you just want to pause the charging session, just go lower than 6A with the maximum current. |
|
no autocharge is off. am still checking settings in the manufacturer dashboard . could it be relate to something like this? |
Like muewe mentioned, YOU SHOULD NOT MESS IN MANUFACTURER SETTINGS! :) |

Ich habe eine freigeschaltete "Juice Charger Me" Wallbox und zugriff auf alle notwendigen Parameter der Wallbox. Die Dokumentation habe ich aus der WB ausgelesen. Mit openHAB habe ich bereits die Stufenweise Erhöhung des Ladestroms von 6A auf 16A über Modbus erfolgreich getestet.
Die WB bietet bei Modbus 3 unterschiedliche Register-Sätze an (Phoenix, TQ-DM100 sowie Open Modbus Charge Control Interface OMCCI). Registertabellen sind beigefügt.
Die Integration über Custom habe ich noch nicht hinbekommen. Eventuell helfen ja die Dokumente um eine Implementierung zu erstellen?
