This would a small box, say 2x5 or less, with 2 digits of display & 2 pushbuttons. Within, a temp sensor and 1-wire interface.....
These would be the thermal sensing end of a new furnace zone system a friend is building himself.
The hard part is making this public part look nice. Has anyone spotted a surplus box being sold that has a display already?

I have seen and used 3 digit (not seen any two digit) drop-in panel mount voltmeters that have a nice bezel. You are likely going to have to come up with a way to consistently cut the right hole in the right place on each lid. That's all. There probably is a pre-integrated unit out there somewhere, but it isn't worth the time lost hunting it up. The panel mount displays and the boxes are easy to find. The pre-integrated version may not be.
I'd start with the usual suspects for enclosures (Polycase, Hammond, Rose-Bopla, OKW) and integrate a simple LCD character display. For the display, the EA-DOG
formatting link
8x1 might work. This is a DIP form factor so you could put the whole thing on one PCB inside a case with a clear top.
If it were me, I'd put a bluetooth interface on the main box and use $1 garage sale PDAs to do the remote (and local) user interfaces. Once you have the infrastructure, you'll think of other stuff you can do with it.
Thanks for the on-topic response. I don't see they sell any matching bezels which throws it back into the "lots of PITA making it look good" dept. Sigh.
Re: other replies.
I don't want a thermostat, thermometer, or even a Theremin. I want a box with a display. I will make it measure temperature, display setpoints, phases of the Moon, whatever. It will have a
1-Wire sensor and some 1-Wire way of driving the display. But for now, I'm box-hunting.
I don't want Bluetooth. We have very fire wires just waiting to be useful.
