Connect Virtual Thermostat to Temperature Sensor

I’ve installed a virtual thermostat and was wondering if there’s a way to have the temperature reading that it shows be linked to a temperature sensor. Thanks!

Which Virtual Thermostat DTH?

If it has an “updateTemperature()” (or similar Command) defined, then it is a pretty trivial SmartApp to call this Command whenever a subscribed Temperature Sensor is updated.

Simulated thermostat.

Yup… The SmartThings “Simulated Thermostat” has a “setTemperature()” Command that you can use in a SmartApp to write the Temperature from a Temperature Sensor. It also then evaluates the temperature value to see if that triggers heating or cooling.

          	evaluate(value, device.currentValue("heatingSetpoint"), device.currentValue("coolingSetpoint"))
          }
          
          def tempDown() {
          	def ts = device.currentState("temperature")
          	def value = ts ? ts.integerValue - 1 : 72
          	sendEvent(name:"temperature", value: value)
          	evaluate(value, device.currentValue("heatingSetpoint"), device.currentValue("coolingSetpoint"))
          }
          
          def setTemperature(value) {
          	def ts = device.currentState("temperature")
          	sendEvent(name:"temperature", value: value)
          	evaluate(value, device.currentValue("heatingSetpoint"), device.currentValue("coolingSetpoint"))
          }
          
          def heatUp() {
          	def ts = device.currentState("heatingSetpoint")
          	def value = ts ? ts.integerValue + 1 : 68
          	sendEvent(name:"heatingSetpoint", value: value)
          	evaluate(device.currentValue("temperature"), value, device.currentValue("coolingSetpoint"))
