What controller are you using (optional)?

“I chose the NodOn relay because it is one of the few Zigbee relays on the market which has UKCA and CE marks. It was bought to control a basic on/off bathroom fan via Home Assistant, and it connected to my existing Zigbee network exposing the relay switch and state, also acting as a relay/repeater for other Zigbee devices. The terminals are clearly labelled and make a good connection onto the cables.”
