My “smart” bulbs are at the less online end of the spectrum, they host local wifi or bluetooth for configuration via their app, but even that can bite you

I added a wifi range extender to address the problem of stuff at one end of the house regularly losing connection and needed to point one of a particular brand at the new wifi

Its app hadn’t been updated and I needed to dig out my old phone stuck on an old version of Android to set the bulb up again
