I'm looking for advice on how to approach the following scenarios.
My client has an outside fountain that he wants to come on at sunrise and turn off at sunset. That's easy enough. However, the added wrinkle is that he does not want the fountain to run if the outside temperature is less than 35 degrees, since there is a possibility of freezing.
I'm trying to figure out how I can program this switch with both the sunrise/sunset time and make that dependent on the outside temperature as well.
He is also asking if there is a way that I can program exhaust fans that he wants in his garage that will turn on and off based on the temperature within the garage itself. So if several hot cars are sitting in the garage, the temp rises, and the fans runs until things cool off. Then turn off.
I've never seen anything that would allow a Radio RA switch to get commands from a temp sensor, but I'm hoping there is something out there for this. Both sond like reasonable requests from the client.
