From what I understand, Alexa can only be triggered with person detection. Unless you are a Cam Plus subscriber, you won’t have access to person detection. Which also means, if you don’t subscribe, no Alexa routine can be triggered by your Wyze cams. If you have opted to use person detection during the testing phase, Wyze is apparently granting you free access to person detection until the end of 2020.
But this still does not allow the regular motion on cameras to trigger an Alexa routine. But here is a way to do this and it’s a completely free solution. I am thrilled as it works perfectly!
