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
  • Sensor: reports on the device’s detected temperature and uptime
  • Switch: allows the user to open and close the valve


This integration can be configured via the Home Assistant UI by navigating to Configuration -> Integrations. If you have the zeroconf integration enabled, Home Assistant will automatically discover any Guardian devices already connected to the network.
