I am working to automate several of my pool functions and incorporate them into my backyard automation project. I have the pump and pool lights done. I am working on the valve for the waterfall. I need a SPDT 24VAC relay I can use to actuate the valve. I have looked at the mimolite and it looks like it will work. The issue is space. By the time I use 12VDC to power it and install a 24VAC transformer, and the mimolite it gets rather crowded in the box. What else have folks used for these kinds of applications?
