Home Assistant

Elexa Guardian

The guardian integration integrates Elexa Guardian water valve controllers into Home Assistant.

There is currently support for the following device types within Home Assistant:

  • Binary sensor: reports the status of the onboard leak detector and access point
  • Button: add various configuration controls
  • Sensor: reports on the device’s detected temperature and uptime
  • Switch: allows the user to enable and disable the onboard access point
  • Valve: allows the user to open and close the valve

Configuration

To add the Elexa Guardian integration to your Home Assistant instance, use this My button:

Elexa Guardian can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

Paired Sensor Notes

When a paired sensor is first added to the valve controller, it may return inaccurate or nonsensical values for several of its attributes, such as battery and temperature. This is due to the sensor never having communicated its data to the valve controller and can be fixed by moving the sensor around (so that it beeps, indicating that data has been sent to the valve controller).
