roofwater

Run my sprinkler at regular intervals when it's too hot outside.

I put a simple sprinkler system on my roof with a cheap tasmota powered water valve controlling it. This software interfaces with the tasmota valve and runs it at a preprogrammed interval whenever the temperature outside is above a setpoint. This requires a OpenWeather API Key.

Usage

This application is configured via the environment. The following environment
variables can be used:
