https://beelogger.de/ is the logger info code parts etc if you havent seen that yet. but like others have mentioned humidity would be a plus. or 1 step up. what if at a certain temp range it triggers servos to open a vent or close the vents if it drops below a temp threshold.
what was prohibitive for my setup was power and signal. my hive is deep. like 1 hr from my house in ft worth. and then another 100 yards from the main house. with no power around. so i looked into solar… which is less than efficient it seems. so an entire build was going to be $200+ for a bad quality webcam. might as well at that point go hunter deer cam or something.
so for me the main thing for me is a webcam that i could log in and check since my babies are so far away. moreso than INSIDE the hive like many seem to try…
