First go at a smallish TH sensor that can be deployed anywhere.

@defMondo Suggest you Google physically modifying the board to get really low power in sleep mode, the LED is burning energy etc...
@zboblamont thanks for that, will have a look for that.
If I find I end up deploying a few more of these or similar units I may end up getting a PCB made up where the radio will just plug(solder) in with the bear essentials, similar to the mysensors one except with a different form factor to suit these 4AA boxes.
Thanks, @sundberg84, I ended up mounting the board and then soldering the wires in while the boards were in place which would reduce the chances of braking wires trying to cram them in :-)
@gohan Will look into that thanks, although if the standard batteries last a long time not to fussed about replacing them periodically but I guess the 3.2v would be better to run the arduino and radio from.

@defMondo No need to make your own PCB etc unless you really want to, there are plenty of choices from folks who already trod that path, here and elsewhere... Moteino were one of the first I believe, loads of others since...
@zboblamont thanks for that, the Moteino looks good except I'm trying to go with the nRF modules, would be great it it could come with one of those. Found a few others as well but haven't seen one in the right format for my needs, but yeah will look further before getting my own ones made, not a fan of surface mount soldering with a normal iron.

Thanks for the links @sundberg84 , I was aware of the mysensors stuff I like the formfactor of the Sensebender Micro althought not a fan of the internal temp sensor. I guess you can always ignore it.
Have only had a quick look at the OpenHardware site will look more closely tonight, see if anything jumps out at me.

I'm pretty sure NModule with TH/Door shield will fit in your box, or just NModule with wires to your temp sensor ;)

Similar setup using 4AA enclosure but using sensebender micro, batteries being running for more than 6 months and only 50% used.

Then you probably have a lot of room for improvement, AA batteries have a huge capacity compared to CR2032 (10 times more) and my temperature sensors are going to run way over one year if I believe the battery readings.
At what voltage are you running your sensebender micro ? -

Using 2x AA batteries (3V)
Current multimeter reading is 2.75V, reading on Vera is 57%.
Looks like reading on Vera is out.
I've stuck on a sticker with today's date to see how long sensebender will go on, probably a few years.
