I’m looking for a water pressure and flow sensor. I would prefer a plug and play but am having a hard time finding either a pressure or flow sensor that is. I have used a couple of esp32 devices, the RATGDO and a esp32 for my Rheem water heater. Both where pretty close to plug and play, all I needed to do was flash a pre-made firmware. I have no experience with making my own yamal file or modify code to flash to the esp32.
If someone could recommend a plug and play sensor that would be just flashing firmware or point me to a very detailed how to that I can follow I would be very grateful.
