Using an ESP8266 ESP-01 module and an Arduino Pro Mini 3.3V I wirelessly update all outputs from my thermostat to here for data analysis and because it's cool.
This requires a voltage divided rectifier since thermostats run at least 24 VAC RMS.
My Worm Farm
Wakes up every 15mins, turns on GPIO13 to power soil & air sensors. Takes readings, turns off 13 then turns on WiFi and sends data to ThingSpeak. React & ThingHTTP trigger IFTTT to issue alarm on my phone. Then ESP.deepSleep for 15min.
