Of course! From an end-user the experience between Bluetooth and ZigBee sensors is basically indistinguishable, except for range.
I have a detached garage, on the opposite end of my property from my HA controller, so the Bluetooth sensor out there specifically was a little flaky. The BT sensor is rated for ~160 ft but realistically it’s 50-100 ft if your home has walls.
Swapping that one sensor to ZigBee so it could tie into my mesh network solved the problem. All other BT sensors have had zero issues, and their AA batteries unsurprisingly last longer than the 3R ZigBee AAAs, but both last at least 6mo.
Some Shelly devices can be used as “Bluetooth repeaters” but I’m unsure of the specifics of how that works.
Fair point! As far as I can tell, the temp sensors are just beacons - anyone can connect and see that somewhere in your house it’s 72 °F, but who cares ¯\_(ツ)_/¯
If you’re running on a Raspberry Pi, you can just use the onboard BT, whose drivers are updated regularly.
ZigBee ones get occasional updates automatically detected through HA, and have to be moved to somewhere near the controller to update. I assume, as temperature and humidity sensing hasn’t changed, that these are security patches.
BT ones get no updates, which either means their security goes unpatched, or it really doesn’t matter when all they do is shout out measurements into the void.
