KeyError '3' - Missing support for Zone 3 in G13 tariff

[tklakla]

Integration crashes when processing Zone 3 data from G13 tariff.

Error:
KeyError: '3'
File: sensor.py, line 255
zone = zone_names[consumption["Zone"]]

G13 tariff has 3 zones, but zone_names dictionary only includes zones 1 and 2.

Home Assistant version:
Integration version: v2.7.1
Meter ID: 590322429303033037

zone_names = {
"1": "peak",
"2": "off-peak",
"3": "super-peak" # ← Add this
}

Zone names are downloaded from Tauron. Have you changed tariff recently?

[tklakla]

nope, but error apeeared:

Does everything work despite this error?

I am experiencing the same issue where the integration fails to update, resulting in missing statistics. I managed to debug this by enabling debug logging and checking the API response against the traceback.

The crash occurs because of a KeyError in sensor.py when the code tries to map a Zone ID found in the measurement data to a name defined in zonesName.

1. Traceback The error happens in get_balanced_data when accessing zone_names[consumption["Zone"]]
   2026-01-04 23:00:23.468 ERROR (MainThread) [custom_components.tauron_amiplus.coordinator] Unexpected exception from <bound method DataUpdateCoordinator._async_refresh of <custom_components.tauron_amiplus.coordinator.TauronAmiplusUpdateCoordinator object at ...>> Traceback (most recent call last): ... File "/config/custom_components/tauron_amiplus/sensor.py", line 174, in _handle_coordinator_update self.update_balanced_data(data.balance_yearly) File "/config/custom_components/tauron_amiplus/sensor.py", line 209, in update_balanced_data balance, sum_consumption, sum_generation, zones, data_range = TauronAmiplusSensor.get_balanced_data(con, gen) File "/config/custom_components/tauron_amiplus/sensor.py", line 255, in get_balanced_data zone = zone_names[consumption["Zone"]] KeyError: '3'

2. API Response Inconsistency Looking at the debug logs for the data being processed, the Tauron API returns a zonesName dictionary that only contains key "1", but the actual hourly data in allData references "Zone": "3".
   { "success": true, "data": { "zonesName": { "1": "Reszta dnia (T3)" }, "tariff": "G13", "allData": [ { "EC": "2.534", "Date": "2026-01-03T01:00:00.000+01:00", "Hour": "1", "Status": "0", "Extra": "N", "Zone": "3", "ZoneName": "Reszta dnia", "Taryfa": "G13", "WorkName": "T3" }, ... ] } }
   The code expects the key "3" to exist in zonesName because it appears in allData, but the API only provided a definition for "1". This mismatch causes the KeyError.

Please check v2.7.2 and confirm if it works

It doesen't work for me.

[tklakla]

for me - it's working :) but I can't notice anything special with this tariff, how to get info about particular zones in G13 [image: image.png] [image: image.png] śr., 25 mar 2026 o 21:07 mareckii ***@***.***> napisał(a):
