I thought it did, but I just checked Alexa automations and the camera settings in Alexa and maybe it only allows Person Detections now.
So, you would probably have to use some 3rd party workarounds.
I don’t know about IFTTT.
You can for sure do if you use an RTSP converter like Docker Wyze Bridge to get the RTSP streams, then use a program like Home Assistant to sync motion detection as an exposed binary sensor through Alexa, or just integrate Alexa into Home Assistant and have Home Assistant control it directly. I do this for a lot of things. I make Home Assistant push TTS messages through Alexa dozens of times a day to tell me exactly what’s going on with a number of devices or where certain family members are. For example, if my wife is just getting home from the grocery store, I have it tell me that so I can go meet her on the driveway to carry in stuff for.
You can actually bypass all of that with a different cool feature though. This is probably the simplest way to do things if you have Android:
Go to this site/service and create a FREE URL Routine Trigger for Alexa:
Then set up to have a notification for any motion on that camera and have an app like MacroDroid or Tasker watch your notifications. When it sees that camera have a notification that says “Motion Detection” you have Macrodroid or Tasker execute that URL Routine Trigger, and it will push that on to Alexa.
I use this to get announcements for various apps that don’t support Alexa, but do support notifications on their app on my phone. If I don’t want a phone notification every few minutes for something like motion detection, I can even have Tasker or Macrodroid INTERCEPT the notification and stop it from ever showing up on my phone, so it never buzzes and I never know about it.
I do things like this all time for lots of things that don’t even support Alexa.
Very useful advanced stuff.
So the summary is, YES there are FOR SURE ways to do it, including many more than I listed above. I just think those are 2 of the easiest free ways to do it.
