# irrigation
Hardware and firmware for an irrigation controller on an ESP32.
Designed to control 24VAC solenoid valves.
## Schematic
## PCB
- PCB has been designed in [EasyEDA Standard](https://easyeda.com/).
- Board size is 140 mm x 70 mm.
- Includes M4 mounting holes.
- 2 layer board.
## Hardware
Use the Gerber files in [hardware](hardware) to print a PCB from your favourite supplier and solder components to the board.
See [hardware/README.md](hardware/README.md) for more information.
## Firmware
Flash the ESP32-C3 using the following steps:
```
python3 -m venv irrigation
source irrigation/bin/activate
pip3 install esptool esphome
esptool.py --port /dev/ttyACM0 erase_flash
esphome run irrigation.yaml
```
The firmware uses [ESPHome](https://esphome.io/index.html) which has default support for Home Assistant.
## Usage
**Initial setup:**
- Connect power to the device.
- Connect to the WiFi network `Irrigation Controller` and enter password `irrigation`.
- Open the web browser to `192.168.4.1` and connect to your WiFi network.
- Find the IP address of the ESP32-C3 from your WiFi router devices list. Alternatively run `sudo nmap -sP $(hostname -I | awk '{print $1}')/24`.
- Assign a static IP to the ESP32-C3 from WiFi router settings.
**Operation:**
- Navigate to the static IP assigned in the initial setup.
- Use the ESPHome web interface to control solenoids.
**Home Assistant setup:**
- In Home Assistant navigate to `Settings`, `Devices and Services`, `Add Integration`, `ESPHome`.
- Add the host as the static IP assigned in the initial setup, and leave the port as `6053`.
- Enter the encryption key found in `irrigation.yaml`.
- The ESPHome device will expose the 8 solenoid switch entities.
## Future Work
- Add pictures of installed controller.
- Design 3D printed case.
