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

[Damon Hart-Davis]

Hi,

The codes have various uses, including manufacturing and field deployment.  Lots of ways of just showing the same ID really!  B^>

We use screwdrivers with a long slim shaft so that the collar nut need not be removed.

Taking stuff off the PCB clearly violates the guarantee, and in any case be careful of adding too much capacitance to the circuit as we only sample for a fairly short time typically.  Unless light is thoroughly obstructed Radbot will adjust itself to respond to typical lighting levels.

I have screwdrivers that would fit if the securing ring wasn't fitted - but with the ring in place, it partially blocks access down the holes.
