Old yeelight bulbs problem maybe solved (almost here)

I am still having problems and errors about yeelight bulbs. Today i tried to not have yeelight bulbs handled by yeelight and mihome app, but only with HASS and suddenly all the errors and problems disappeared magically. So i think problems depends from those apps. Now my question is: if i delete yeelight bulbs from Yeelight and Mihome apps will i have them still on HASS?
I hope you all understand my poor english and if yes there is someone else who discovered this?

Yes you can remove the bulbs from their respective apps. They will keep their Wifi configuration (unless you reset the bulbs), and will be still accessible in HASS.
