[OpenTRV-dev] Some interesting user feedback...

[Bo Herrmannsen]

let me pitch in thou i have rev1

2+3... for me that hardest is to tell when in last mode.. hmmm or did i? 
frost is no flash.... warm is one.... double is boost? so if that is correct 
i got it.... i think.... hard to tell and count

4... i skipped learn too as it would throw it back in to frost after the 
learn period... of course the downside is that the outside light kind of 
controls when it backs down a few degrees... but as most of our windows face 
south there is a balance, but might not be the case for all users

5.... i partly agree... for me the plus is that the temp is messured in the 
room and not near the rad where heat radiation and false readings are more 
likely

7... some of mine are a bit noisy, some of them you cant hear unless you 
stop breathing... it all depends on the pipe works and how well you can 
tighten the conrad... their idea of adapters etc are nice but sometimes the 
fit is to loose...

9... the idea that one press and the mode changes would be better... much 
like on the picaxe version... on that one i press and watch for solid light 
and i know it has changed mode.... do again for next mode etc etc

Subject: [OpenTRV-dev] Some interesting user feedback...

I thought I’d just share this, as it is very interesting.

This is a REV2 unit with temperature knob, two LEARN buttons, and the Big 
Red Button on the front for mode.
