I have a number of Tuya wifi GU10 installed in my home office in the back garden. A number of them are almost always offline. However, if I stand near them with my phone they seem to connect and allow me to control them. I am wondering if they are somehow using bluetooth through my phone to work as they only ever appear to be connected if I am near them. Strangely this is only the case with some and not all. Is this a common thing? How can I keep them connected?
I am currently using the Smart Life app and have the Tuya integration in Home Assistant, but as the lights are mostly offline not much works.
Would a bluetooth hub help me out?
