Review on 🔌 Enhanced Sonoff TH16 WiFi Smart Switch: Temperature and Humidity Monitor for DIY Smart Home, Alexa Compatible (16A) by Samuel Hansen

I thought the TH16 had failed while I was abroad. In fact I left a built in thermostat in the line which cut the power as intended. When I came back the TH16 was working really well. I use an EasyHeat 2102 thermistor heating cable to keep the pipes from freezing. The thermistor process reduces resistance as the temperature drops, which in theory saves energy. I found that the static temperature of the pipe is around 92F. This is quite noticeable on the electricity bill. The beauty of this unit is that I can turn off the heater and/or adjust the temperature of the top tube. When he came back two weeks later, he seemed to have reduced my electric bill by about $50. What have I learned? I'm trusting my installation to a $10 switch, so I'm going to run another TH16 in parallel for redundancy. The TH16 is rated at 16 amps, works, and is easy to set up and use. GREAT DEVICE.
