Plant133 Setup Instructions

Follow this guide to assemble and configure your Plant133 watering system.

1. Hardware Assembly

Mounting the Control Box

Hang the EBox on the side of your water reservoir. Place your plant and reservoir in their final location, ensuring access to a USB power source.

Hang EBox

Reservoir Setup

  1. Install the Water Level Float: Place the float into the reservoir insert. Install Float

    Wire the float to the EBox. Wire Float

  2. Install the Pump: For each plant you intend to water, place a pump into the reservoir insert. Install Motor

Wiring and Tubing

For each plant,

  1. Connect Sensors and Pumps: Connect the soil moisture sensor and the corresponding pump to the EBox. Ensure connectors are aligned vertically under the same number (1-4).

    • The soil moisture sensor uses a 3-conductor wire with JST connectors. Wire Sensor and Pump

  2. Run Tubing: Run a tube from the pump, through the hole in the insert, towards the plant pot. Install Motor Tube

  3. Position Water Outlet: Cut the tube to the appropriate length and choose one of the following methods:

    • Method A (Cap): Push the tube end through the hole in the moisture sensor cap. Tube Aimed at Soil
    • Method B (Spike): Insert the tube into a 3D-printed soil spike and insert the spike into the soil. Spike with Tube Spike in Soil

  4. Power Up: Connect the EBox to power using a Micro-USB cable.

2. Network Configuration

  1. Connect to Device AP: Look for a WiFi network named plant133 (or similar) on your phone or computer. Connect to it.

    • Note: The AP password (if set) and specific ESSID may be displayed on the device's OLED screen.

  2. Access Configuration Page: Open a web browser and navigate to http://192.168.4.1. You may need to accept a warning about a non-encrypted connection.

  3. Configure WiFi:

    • Click "WiFi Setup" on the main page.
    • Enter your home WiFi credentials.
    • Click "Save", then "Back", and finally "Restart" to reboot the device. Web WiFi Config

  4. Reconnect: Connect your phone/computer back to your home WiFi network. Look at the device's OLED screen to find its new IP address (e.g., 192.168.1.x) or try accessing http://plant133.local (if mDNS is active).

3. Device Configuration

MQTT Setup (Optional)

If you use Home Assistant or another home automation system:

  1. Navigate to the MQTT Setup page via the web interface.
  2. Enter your Broker address, port, and credentials.
  3. Save. The device should automatically appear in Home Assistant if discovery is enabled. Web MQTT Config

Plant Configuration

Select a plant from the main menu and click the settings icon.

  • Moisture Targets: Set the Minimum (start watering) and Maximum (stop watering) soil moisture percentages.
  • Dose Duration: Set how long the pump runs per dose (in milliseconds).
    • Recommendation: Start with 1000ms (1s) for small pots, 3000ms (3s) for medium pots.
  • Calibration:
    • Wet (100%): Submerge the sensor (excluding the electronic cap) in a glass of water. Note the "Raw Moisture" ADC value and enter it as ADC Counts at 100%.
    • Dry (0%): Dry the sensor completely. Enter the reading as ADC Counts at 0%.
    • Note: Lower ADC values usually mean higher moisture (more conductivity).
  • Dosing Logic:
    • Seconds between doses: Time to wait for water to soak in before checking moisture again (Default: 900s / 15 min).
    • Max doses per cycle: Safety limit to prevent flooding if the sensor fails (Default: 5). Web Watering Config

4. Final Steps

  1. Enable System: In the configuration page, toggle "Enable Automatic Watering".
  2. Fill Reservoir: Add water to your reservoir.
  3. Monitor: Watch the system for the first few cycles and adjust Pump On Time or moisture thresholds as needed.

Advanced

  • Grafana: Set up a dashboard to visualize moisture trends over time.
  • Home Assistant: Create automations to alert you when the reservoir is low.
