Just in case someone would find it useful (OTA, MQTT, HTTP server events...).

Quoting the README:

Remote control up to 4 solenoid valves with the ESP8266 SOC (Arduino environment).

Either use the integrated web app with your smartphone (point your browser at `http://esprinkler.local`) or let your favorite scheduler send HTTP commands to trigger sprinklers.

At the end of a sprinkling cycle, meaningfull information are published on your MQTT server: which sprinklers were activated, how long did they sprinkle, ESP uptime & heap...).

ESPrinkler can easily be adapted to control different/more devices.
