I'd like to setup two temperature detectors: one outside and one inside my house, in order to compare temperature and act on the difference (opening/closing the window for example).
The issue I'm facing is which platform to take. My initial thought was to go with the Photon, but the price is quite high when I can go for a Raspberry Pi Zero for way much. On the other hand, the Pi Zero requires a lot of power, and since I plan to place one sensor outside, I was hoping to "place it and forget it" at least for a few months, with some AA batteries (one? two?) on it.
So I'm asking for your help. I'm open to other platform to implement my plan. Here's what I'm looking for in this platform:
- Wi-Fi capable (or some transmission for the outside remove, and Wi-Fi for the inside)
- Can live weeks, months using simple AAs
- Not expensive. It's just a small side project.
