Thanks for making it available. I built the v0.1 edition and used an 18650 battery, rated @ 2600mAh, (could be wrong / fake). I made the following changes:
Battery lasted 5 months with the sensor attached to the front door, the circuit stopped working with battery @ 2.3V, which exceeds the voltage regulators specifications.
I paired it with a DS90 sensor and monitored both to see how reliable each of them were, and I think for 99% of the time, both were identical. The ESP would occasionally drop a "CLOSED" signal, if open/closed happened quickly enough.
For this reason I think a watchdog timer waking up the device every x minutes, and reading the current state, would probably be a good idea.
While I had hoped for 12 months of running time, I'll need to see if the battery holds the promised capacity, and see if its possible to trim the timings to lower power usage.
Do you have any data for real-life running of your own?
