Water Pipe Temperature Sensor

[ogiewon]

I monitor the temperatures of my Heat Pump Freon Lines using DS18B20 temperature sensors like the following. I also monitor the Heat Exchanger Inlet and Outlet Air Temperatures. So, 4 DS18B20 sensors in all.

I have these tied into one of my NodeMCU ESP8266 microcontrollers running my ST_Anything Arduino software. I actually use just 1 digital pin for all four sensors, and each sensor is then created in ST as an independent child device. This allows each one to be used in any automation, like any other temperature sensor.

[DEPRECATED] ST_Anything - Arduino/ESP8266/ESP32

UPDATE 2022-08-17 - Per this recent SmartThings announcement, the Groovy IDE will disabled on September 30, 2022. My best guess is that any existing ST_Anything devices will probably cease to operate at this time, or shortly thereafter. It has been a good 7+ year run for ST_Anything users. I want to thank you all for making ST_Anything a successful project! My son and I really had a lot of fun creating it together, and have enjoyed hearing how you have all used it in so many creative ways. As many of you probably already know, I have moved on from ST and have ported ST_Anything over to Hubitat as “HubDuino”. If you have devices running ST_Anything that you ‘can’t live without,’ at least you know you have options. Another option for ESP8266/ESP32 users would be to use ESPHome along …
