DIY Pool Controller

Node-red DIY din rail based pool automation controller

   • DIY Pool Controller - Node-RED walkth...   for the logic behind the hardware

Parts List:
Terminal blocks: Dinkle. EBay or Amazon. You can get these from Automation Direct as well but I like the Dinkle brand.

Mains relays and circuit breakers (3rd row): Automation direct.

Power supplies/transformer: Meanwell/Electronics Salon both from Amazon.

Pi Relay/ADCs (for instrumentation readings): Sequent Microsystems relay/IO HAT. Probably going to swap out the ADC hat with a different model soon. Sequent Microsystems IO HAT only goes to 3.3v and I don't want to mess with voltage dividers.

Case: Altelix. They had a sale going on. 99$ for this case. I had to buy 2 extra DIN rails. I got the one with the glass door because I thought it'd look sexier in there than it does with all the wiring. If I had to do it over, I might have gone with one of their power vented enclosures.
