[OpenTRV-dev] Current rough to-do list top

[Bo Herrmannsen]

would it be wrong to have case as an task in opentrv calendar running from 
last night until weekend?

just to show the world what we work on... can be extended if need be

Getting a full OpenTRV box first pass kinda sorta ready this coming weekend 
would be in gloriously good time!  Gives us lots of elbow room for 
iteration.

PS. Just 3D printed a set of 'Roman' pan-pipes for my daughters school 
project, and they sort of work!  I am flabbergasted!  B^>

PPS. Have family birthday on Sunday but Saturday potential free on my side!
