I just started using AT, love it so far. I'm considering mounting a tablet to start experimenting with. I'm building a house next year, currently finalizing the design. I'll be doing all the low voltage installation so I need to know pretty soon exactly what I need for smart house items so I can run cabling as needed. I'd always wanted to do a wall mount tablet in a few locations and I think AT will fit the bill.
So for now in the current house, I don't care to dig into sheet rock to run cables for power then have to repair before we sell the house, but I still want to play, mostly to get the wife on-board and so I'm not having to experiment on the new place.
I have a perfect spot downstairs right above or next to my nest thermostat. I do have 5 wires to the nest so I have 24VAC with common available. I was thinking of a AC to 5VDC buck converter mounted inside a picture frame with the tablet. I could poke a small hole in the wall from the nest to behind tablet. Has anyone ever done this? It shouldn't pull more than a half amp at 24VAC...
I'm not sure what size AC transformer is in my HVAC system, it's a Lennox system about 2 years old. Also not sure how much power the nest requires.
