Last weekend I installed a misting system in my patio garden to help cool down the space during the hot summers in Madrid. The system uses a pressurized water line managed by a Zigbee solenoid valve. The valve is supported and controlled by my Home Assistant setup via Zigbee2MQTT.

Rather than keeping the misting always on (wasting water and risking over-saturation), I wanted a smart automation that:

  • Activates misting only when I manually trigger it,
  • Adapts to weather conditions like temperature, humidity, and wind,
  • Automatically cycles on and off for as long as it’s active,
  • Lets me cancel everything with a single press.

The result is a reusable Home Assistant blueprint that anyone can install and tweak for their own use.
