Good to know, thank you. I think the only thing I worry about with BT is vulnerabilities. Not sure if ZigBee is any more secure but I’ve heard of a lot of BT vulns in the past. Probably doesn’t matter for a temp sensor, so probably just important for the dongle/driver being used with HA.

Oh I’ll check them out, thanks

Awesome thanks for the suggestions :)

Good to know, thanks :) yeah it does seem a bit spendy.

Thanks for the recommendation!

Couldn’t find any 3V cr2450 rechargeable, do you have any idea if they exist?

Cool alternative, thanks!
