Toggle irrigation system from local weather

Blueprints Exchange
1

This blueprint was made to make irrigation control easier by rain, wind and temperature sensors.
This depends on a wind strength sensor, a current rain sensor (if not raining returns 0 as state), a temperature sensor, and a relay or switch controlling the irrigation system.

Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.

Why?
I mean what’s the matter with wind Or temperature?
It’s mostly about the time between the start and the moister.

So I’m slowly building automations for home, and my parents wanted an automation, to turn off the irrigation timer, when the wind is higher than x, because we use well water, and if we run the irrigation in high wind, it stains the white wall of our garage. The reason to share here, because our neighboor, who also uses home assistant, asked for the automation and when tested, for some reason, he couldn’t import the blueprint when i gave him the github link
For now, it’s a hunter “dumb” irrigation controller, and the automation only turns off 1 relay, to deactivate the valves, since my 8 channel relay board didn’t arrive.
