Hello all
I am currently trying to find some Kind of smart switch that can be controlled by switching the Wall switch, an app on my smartphone and my home Assistant. Unfortunately I cannot find any available switches made for the european (german) market but quite a few for the US. Does someone know if something like this is available and compatible in europe?
I got the Aqara Wall Switches (they are Zigbee, you will need the Xiaomi Gateway 2)
No personal experience with this, but here’s a post that says WEMO works in europe:

Hello, try www.shelly.cloud. This is bulgarian it company. They offer REST switches, and i think they can sell worldwide.
I have these: Sonoff Touch
Works in Switzerland 
You have to flash the Firmware from here to integrate them with MQTT to Home Assistant.
