Hello,
I plan to automate my pool pump, to run depending on solar heat system. Basically, i have following hardware:
- ESP with Dallas sensors integrated in HA
- smart-plug ( relays connected to my ESP32 board, also Sonoff BasicR2 relays
- Regular 220V water pump that flows water in the geating pipies / pool
I plan to make an automatic rule. When water in the solar heat pipes (detected by water Dallas sensor) is with 30•C higher than water in the pool, pump will start to run. When difference is lower than 10•C, pump will stop until first condition is again meet.
Do you guys think will work ?
What to choose between sonoff relays and clasic 5V Esp32 relays ? I mean safe, and hazard risk. Of course i will have earth connection also !
Thank you !!
