As an alternative, we have found bulbs that can run tasmota with the MQTT integration to be perhaps the most reliable part of our smart home (as long as the hardware already had a descent CRI). I’ve heard good things about ESP home too, but we have not tried it.
If someone has some light bulbs that are laggy (due to cloud integrations) or a pain to use due to software, its worth checking out of tasmota or esp home can be installed on them to locally pair with something like home assistant. It turned a regretful purchase into a nice addition.
With that said, we don’t buy connected devices any longer without checking internet and cloud requirements first.
The ones I had you could do it over the air, but some do require access to the pins. Even with soldering experience it is not approachable as bulbs are not packaged to be opened, it is part of why I check for offline or flash compatibility before buying as even the same “model” could have different hardware revisions. No info = avoid.
