[OpenTRV-dev] REV7 board working and talking!

[Damon Hart-Davis]

Hi,

The bigger issue is to work out what we *want* to do.

For example, I don’t want to waste energy turning *up* the target temperature unnecessarily.

What it might be good to know is a set of danger temperatures and RH% for (say) mould growth, plus mite growth, and have a way of deflecting the target temperatures around those values.  But it will be subtle and generally we want to manage things by reducing temperature.

A ‘bathroom’ mode might be different, maybe doing a BAKE if humidity goes too high.  (Though a recent trialist feedback would suggest that might not be universally popular.)
