That’s frustrating. Looking at it once today in the Google Home app, I got the “Connecting” message with the spinning indicator for several seconds before it gave up and showed “Live video unavailable”. Fortunately, the “Retry” button on that screen worked for me in that instance.
Back to the original topic of this thread, I asked on Wyze’s Discord server about using Google Home smart speakers as a chimes and @carverofchoice shared a helpful link from another forum thread, which worked for me. I haven’t yet taken the time to read that entire thread, but I did see a link there that describes the “doorbell press event”, and from there I learned that there’s a Google Home for web tool that allows automation scripting, so I might play with that when I can devote some time to it.
Hopefully you at least had a successful installation of the doorbell and can use it in the Wyze app. If you’re like me, part of your interest in these sorts of things is specifically getting them integrated into Google Home so that you and other family members can use that as a one-stop shop for interacting with your smart things and also have those things talk to your other things (like having live camera feeds show up on your smart displays). Having said that, there are cameras in this house from another manufacturer that won’t show me a live feed in the Google Home app but will show me the feed if I ask Google Assistant to stream it on a TV or Hub. I’m sure someone who knows more about these things than I do can explain that.
As frustrating as it is when these things don’t work as expected (and I definitely get frustrated with technology), sometimes I step back and think about how amazing it is that these things work together at all for me as an end user. Clearly people a lot smarter than I am have spent a lot of time designing systems and devices that work in a way that seems simple and makes it easy for me as an average person to use.
I don’t imagine any of this helps your situation, but maybe something in that other thread will.
