eWeLink SA-003-ZigbeeOnOff ControllerZHA (Home Assistant)Zigbee2MQTTdeCONZ+3✓ Works with 6 platformsWe list 36 Zigbee switches & relays confirmed compatible with ioBroker. Each one also shows every other platform it supports.
Not every switch or relay is supported — it depends on whether ioBroker (or the underlying bridge) has a device handler for it. The list above is limited to switches & relays confirmed to work with ioBroker.
You need a Zigbee coordinator (USB stick) connected to ioBroker. Once the coordinator is set up, you pair the switch or relay and it's controllable from ioBroker.
