I also wanted to pilot my Tuya devices (lights) using my new xiaomi GW v3, but it fails! once you are on european servers, the xiaomi home app has no feature to connect with Tuya account
the GW is also not seen in Alexa, despite xiaomi skill activated....
I wonder if buying xiaomi hub was a good idea.....
