How to Trigger Alexa Routines with Anything From SmartThings

How to Trigger Alexa Routines with Anything From SmartThings

One of the hardest things to do right now is to trigger Amazon Alexa routines with any device or any condition from Samsung SmartThings. Right now, what you can do is attach Contact and Motion Sensors to Alexa and use those to trigger Alexa Routines, but what if you want to trigger with something like a Leak Sensor? What about temperature? Humidity? Lighting levels? What about a certain time of day, plus the presence of someone in your home?

These are the kinds of requests I get each and every day on Automate Your Life and as such, I went out and found a solution. Now, full credit to BJ Pierron who wrote this Device Handler code for a specialized device type that will allow you to do this.

You can use code for SmartThings to make your own Simulated Alexa Switch. The simulated Alexa Switch code for SmartThings is provided by ‘bjpierron’:

Thank you so much guys! I was able to modify the code to also acts as a motion sensor, now i can use all my Echo paired Zigbee devices into the smarthings app.

I tried the above fix. I was able to get the device handler and the device uploaded. When I go to the app the simulated switch does not show in routines. It does show up as a device. There is a note at the bottom of the list of available devices that says devices without available conditions aren’t shown. Any suggestions?

Thanks Alan, appreciate your work – this is super helpful. This works well with almost all devices. The only routine I am not able to run is getting Alexa to open garage door or driveway using a YoLink controller (i.e. as a trigger switch instead of a passive switch). This may be an Alexa restriction. Because when I go to create an Alexa routine where ST virtual switch triggers a YoLink controller in Alexa, it shows that my only option is to CLOSE the YoLink garage/driveway controller, with no option to OPEN. So it’s great if I forgot to close the garage and need to close it. But not if I lost my physical controller and want to open it from ST app.
