Hi folks,

I want to share my latest project: Building a lawn irrigation controller powered by a 9V battery and operated directly from HA dashboard.

I used only out-of-the-box HA components. With a simple card, I can program my lawn irrigation using CRON expressions, control the sprinkler stations directly using MQTT switches, and toggle the irrigation system based on the current weather conditions.

The controller itself is based on an ESP8266 that interacts with HA using MQTT.
