How can I connect Yeelight Arwin 450S to Yeelight account and Mi home account at the same time?
Yeelight app and Mijia app use the same account and password. You can choose any app to connect the device. Select the same server in another app, and you can see the device
Thx a lot! The problem was in different servers on Yeelight and Mi accounts. I have got Russia and Chinese mainland servers at the same time. Now problem is solved
