As much as we are all anticipating the coming feature for alexa to be able to notify us in the event one of our wyze sensors are opened/closed. I have spent the past 2 hours in forums, and in apps figuring out a workaround that allows for alexa to notify you when a door opens using the wyze contact sensor.
It’s a longer one, but I’m going to be a thorough as possible.
First thing you need to to is: have alexa’s app installed
Second thing you need to is: Create 4 virtual devices for samsung smart things using this guide I found here: https://community.smartthings.com/t/release-virtual-alexa-switch-button/135361
You create the handlers on the smart things developer portal.
The developer portal is on this next link as well. (sorry can only post 2 links, I’m a newbie) Follow this guide to create 2 new virtual devices in smart things: https://community.smartthings.com/t/faq-creating-a-virtual-device/11282
You create one set of 2 handlers per single contact sensor. More on this in a bit.
Once you have created the handlers in smart things dev portal.
Add them to your home
Open the alexa app and link samsung smartthings
Now it gets a bit tricky.
You essentially have to use IFTTT to trip the sensor for smartthings with the wyze sensor as seen in this photo:
Then, once you have successfully triggered the switch with IFTTT and WYZE, you ask alexa to preform actions based on the switch you just turned on via IFTTT.
Now, you use both the handlers to switch off the switch once the door opens. Otherwise, the switch will only fire once and you will have to somehow switch it back off to get it to fire again. As of right now, alexa is notifying me anytime my front, or back door opens, with a customized announcement from the echo of my choice, with a notification that details which door is open.
Takes some tricky working out, but I got it working. Knowing my luck, they will release native alexa support days from now for wyze sense. Oh well, it was a fun project. Let me know if I can help.
