/Much/ better. 28uA when using the same sleep test. Wonder if I can get it down further.

Ive done a little bit of testing tonight. Running off the batteries I got a powrr consumption of 22uA. When I connected the battery to the 3.3av step up and used that to power the Atmel it increased to 81uA. 4 times as much.

I was playing around with my barebones last night (YJ), programming it with my USBasp. It was programming fine but as soon as it reset to actually run the sketch nothing happened. It would occasionally work when I switched the jumper on the USBasp to 5V instead of 3.3V.
Strangley plugging it into the battery worked fine. I think I shorted something on the programmer (I plugged the + and - into the - on the breadboard) and broke something on it.
Had another 1 (supposed to be 2, only 1 turned up) Atmel chip turn up but couldn't get that one to work at all.

This has been driving me nuts. I've been modifying the examples for the temperature sensor and radio to test switching them on and off and I could get them working. When I added it to my temp logger code things didn't work. AARRGGHHH!!
I /think/ I may have finally cracked it though. Not sure it is working 100% reliably though, I will have to test that. But I have something on a breadboard that consumes about 4uA when sleeping. Should last a while on batteries.
The radio works fine. It was the temperature sensor that was the pain! The 3.3V step up uses about 90uA not doing anything so I didn't want that going all the time.

I had forgotten I'd ordered this. I think I must have done it when I'd had too much wine. Turned up this morning. 10x Atmega328ps and crystals, caps, etc.

How much does that work out per complete unit?

28 days later. No zombies. Wireless sensor still going strong. Should get at least another 2 months from it.
Added some CSS to my boiler interface so looks a little better. No mountains in the screenshot for Pete though.
