Did you try the newer “Ready to Go” batteries, like eneloop ? The claim to have a low self discharge rate.I already use them but I have no experiences in such a low power enviroment.

Since you're making an enclosure -- the ceiling mount -- perhaps it'll work out smoother if you're not mounting enclosures w/in other enclosures?</p> <p>Looking forward to seeing this evolve!</p> Maybe ditch the battery pack to save space, use clips or something?

I may add one or two 1-wire sensors to one unit, down the wall, at eye and floor level perhaps, to get an indication of the temperature gradient.</p> Good point – temp & humidity readings will not be optimal.

I like it. Probably not disturbing anyone or anything up there. Only thing what came into my mind that temperature may be a little bit higher close to the ceiling than on eye level. I'm actually not sure, just guessing. But if it is so, it can be taken into account in the readings.</p> Looks quite nice, actually. I like it. Probably not disturbing anyone or anything up there.
