BSEED TS0003Touch Switch 3 GangZHA (Home Assistant)Zigbee2MQTTZigbee2Tasmota✓ Works with 3 platformsWe list 33 Zigbee remotes & buttons confirmed compatible with Zigbee2Tasmota. Each one also shows every other platform it supports.
Not every remote or button is supported — it depends on whether Zigbee2Tasmota (or the underlying bridge) has a device handler for it. The list above is limited to remotes & buttons confirmed to work with Zigbee2Tasmota.
You need a Zigbee coordinator (USB stick) connected to Zigbee2Tasmota. Once the coordinator is set up, you pair the remote or button and it's controllable from Zigbee2Tasmota.
