Wyze Simulated Sensors and Home Monitor

Hi all:
I have Wyze sensors working perfectly and want to integrate them to ST using IFTTT. so I can use ST Home Monitor to manage my alarm.

I’ve created a device of type “Simulated Contact Sensor” in ST IDE to connect my Wyze sensor through IFTTT but when I try to create the IFTTT applet, the sensor is not listed as an available sensor in the trigger definition.

If I change the device type in ST to “Virtual Switch”, I’m able to see the device in the IFTTT trigger definition, but I’m unable to use it together with ST Home Monitor, because it’s not recognized as a Contact Sensor. Any clue of what I’m doing wrong?

You mean The simulated sensor doesn’t show up in the “then“ part of the applet, yes?

Smartthings doesn’t give us very many ways of actuating a simulated sensor.

There are two that work right now, but both will go away once the groovy cloud goes away, which is supposed to be in a few months. And I don’t know if there’s going be a substitute or not. So you could try one of these for now if you want, or you can wait until the transition is done and we find out what’s available in the new architecture


  1. use webcore. There’s a way in webcore to actuate a virtual sensor, I don’t know what it is, but you can ask in their forum and someone will help you. See The community FAQ:

FAQ: What is WebCoRE? (And what was CoRE?)

  1. use a groovy DTH which is BOTH a sensor AND a switch. Then when you turn on the switch, the sensor looks like it opened. When you turn off the switch, the sensor looks like it closed. I myself use this for integration with Alexa routines (not SmartThings routines) as do many other forum members. That’s because you can trigger an Alexa routine from a sensor, but not from a switch. But this way you can turn the switch on and off with any smartthings automation or just with echo.

Again, though, groovy is going away pretty soon, so I don’t know if you want to spend much time on this method.

So those work, but they are only short term solutions.

Hopefully there will be an alternative in the new architecture for an actionable virtual sensor, but I haven’t seen one yet. :thinking:

Hi JDRoberts:

Thanks a lot for taking the time to guide me in such detail. I actually used WebCoRE and things are working perfectly, I’m already looking at new automations leveraging the flexibility of the tool. I appreciate your support.
