Zigbee is not easy to find relays in general. These are not dry contacts, so I add a regular relay to the Zigbee relay to isolate the voltage from its contacts. It’s one extra step, but not hard or expensive. These Zigbee relays, as just relays themselves, being closed by Hubitat Elevation, have been 100% reliable for me. Not at all the experience of battery powered Xiaomi devices.
