[OpenTRV-interest] Cut heating costs with Radbots on your radiators - Much More With Less

[Damon Hart-Davis]

Hi,

The Radbot does have a radio.  All comms are encrypted and each device has its own key, and without that key, although Radbot does send a data frame every 2 minutes, you can’t use it.

The dongle is to connect up to (for example) the 4800 baud serial CLI.  We had to keep production costs down, so there are just pads on the board.  A dongle is the easiest way to get to them.  Thos pads are much the same as those exposed on a REV7 (TRV1) for example.

I will send you a discount code privately.  It’s somewhat better than those in the reviews; please do not share it!  B^>

Rgds
