Miio lights

The last few days lost all my Xiaiomi Miio lights - trying to reset them without much success. Anyone had the same ?

It happened to me several months ago. Check the tokens as in my case they were all changed after a reset of the lights…

I wondered that, now trying to reset the lights without success plus getting the new token. Switching them on/off five times doesn’t always reset the light, shame there is no other way to reset.

Do I still have to add it to the Mi Home app, or can I get the token without adding the light to the app.
