Hello, i need some help. I want to monitor the house water temperature and turn on/off the water heater through smartthings. Is there a compatible controller to read the signal by a PT 100 sensor? The sensor can be connected to a https://www.hicomponent.com/pt100-to-0-4-20mA-converter-rtd-transmitter.html in case the signal is not recognised? Please advise.
