Use Temperature Sensor to start Heater?

I’m trying to control a switch based on temperature, (turning on a heater when cold). But when I set up the Automation, I see no option to select a temperature.
Any suggestions?
Thanks Lucas

I’m not sure what you are using to create the automation, but it sounds like you’ll need Core or Webcore to do what you want.

I’m using the Regular SmartThings automation (just learning about this)

Just reading up on webcore, looks like that is my missing link.

If you use the Classic app, you can choose “It’s Too Cold” under Add a SmartApp, which will do exactly what you need off the shelf without needing to get into WebCore. I’m not sure if there’s an equivalent in the Connect app.


I have not installed a smart app, just looking at that. I will try that first. :grinning::sweat_smile:

Have a Look at the smart lighting smartapp.

I tried the standard "climate control app and it works :relieved:

Now that the temp thing is working can anyone recommend a good smoke detector?

a couple years ago seemed like there was only one choice, First Alert ZCOMBO (Zwave). There are probably more now.

Battery usage is slow but it seemed to alert on 80% or so, that was annoying. But it took about a year to get there so it’s not terrible.

If you have access to RBoy Apps you try some of these apps which allow you to use switches to control the climate through heaters, coolers etc:

[RELEASE] 5-2 Day Programmable Thermostat Scheduler (Weekday, Weekend) with Remote Temperature Sensor for each Schedule

[RELEASE] Humidity and Temperature Management with Scheduling (homes without HVAC/thermostats / using heaters and cooling appliances / vacation home / remote homes)

I am missing something here. I have a heater I want to turn on based on a temp from a sensor. I see that is easy to do based on the smart apps recommended above. But then I want to turn off the heater when the sensor gets to a certain temp. I don’t see that option in the apps recommended. Am I missing something?
