i am looking for a 1 CH 2 Way smart light touchswitch. Theese are very hard to find. I found a model on AliExpress from BSEED. This device uses ZigBee and is compatible with the Tuya App.
I want to use as few gateways as possible.
Can I use this switches directly with my ZigBee Stick plugged into HA?
Depending on whether you’re using ZHA or Zigbee2MQTT they may work immediately or you may need to work with the developers to add support.
Tip is to buy a couple of CC2652P-based Zigbee Coordinator USB adapters and test both Home Assistant’s own ZHA integration as well as Zigbee2MQTT. They can both support more or less all devices that follow the Zigbee specifications and have some different benefits, (ex. ZHA is very easy to get started with while Z2M allow for more fleixble installation options), so good idea to try both ansd you can always re-use one of the Zigbee Coordinator USB adapters as as “Zigbee Router” device (a…k.a. Zigbee repeater/extender) by flashing a other firmware for that. Read https://www.home-assistant.io/integrations/zha and https://www.zigbee2mqtt.io/guide/installation/03_ha_addon.html
