Need a smart hose valve that can run based on the outdoor temperature
What's the easiest way to accomplish this? Basically I have a water hydrant that is fed by a well. I want to add a cooling section for my livestock where when the temperature is above a certain level, like 90f for example, the valve opens and some sprays get a nice cool mist out and any animal that wants to cool down can go enjoy it.
The well pump has a pressure switch so it will just pump water as needed.
How can I accomplish this without a really complex setup.
