Well here I go again, buying gadgets.
It has 16 relays so I can turn all kinds of things on and off, including lights. The relays are rated for 2 amps so they'll handle the linear actuators for the sides and gable vents.
I already have a unit with four analog inputs. This one has four analog inputs for a total of eight. Analog is the expensive stuff.
I don't really think I need to open gable vent louvers just part way. I do need to with the drop down sides which will take four analog inputs. That leaves four but one's already being used for wind direction which leaves three.
Soil moisture sensors and pressure sensors are both analog so I'm thinking two soil moisture sensors and a pressure sensor. The pressure sensor is in the case of a major leak in the drip system or a tank running dry. In either case, the pressure will drop to zero or close to it and I want to shut the pump off when that happens.
This $125 purchase replaces about $600 worth of stuff I would have bought.
