I have a couple Govee temp/humidity sensors which send out the data as a bluetooth low energy advertising packet -- which anyone can read -- and from what I can tell two AAA batteries should last a year or two. They send out the advertising packet around every 10 seconds so 'low energy' is an accurate naming it seems. Mostly got them to learn about bluetooth and wrote (half a) daemon to log the packets, currently it just prints the data to cout.
