Seems like they are using capacitors rather than regular rechargeable batteries. Fast recharge capable but will probably self discharge quickly when not in use. Not a big deal in this case since it only needs 10min charge for up to 50hr use.
Hopefully they use standard wall warts or diffentiate between their proprietary charger and a standard USB wall charger. I’ve already tried charging my signals twice with my standard usb outlet and didn’t realize it wasn’t charged as expected. Signals and bellows have 12v chargers with USB-A output - very easy to forget and plug into phone charger
Good decision to use 433mhz frequency - I assumed they might use 900mhz
Better penetration and distance but at expense of lower bandwidth - but how quickly do you really need to refresh temps?
