Last weekend I red a very interesting article regarding the Xiaomi Amazfit Bip Watch.
Basically the Android app “Tasker” receive button events from the watch via Bluetooth and process this with free programmable conditions. I installed also the additonal MQTT plugin for Tasker and send MQTT messages to a Pimatic MQTT sensor. A rule check the state of the sensor and start accordingly.
Finally I can switch my house lights or open my Garage Door with my watch.
