So far so good with the dual control. I like it because I have Google Home smart speakers/displays in some rooms and Amazon Echo devices in others. I dipped my toe in last year when I picked up a couple of Echos that were bundled with Matter-enabled smart Wi-Fi bulbs, so setting those up in Alexa and then sharing to Google Home was easy enough, but I was concerned that trying to integrate both voice assistants might muck things up. I took the plunge recently and learned that linking to Alexa from the Wyze app (and other third-party apps) hasn’t caused any problems and has really expanded my possibilities. For instance, now I’ll be able to just use Alexa’s ability to schedule every-other-week routines (something I think Google Home still can’t do natively) for those weeks when I need to put out the 
and 
bins. 
Also not as accurate as Google Assistant in some cases (like weather or word definitions being incorrect and with the wrong etymology). Plus, since I don’t use the default wake word, my Echo devices sometimes want to start streaming a Ziggy Marley playlist. 
Back on topic, I’ll try to do some testing of my own at some point, but I’ll need to move a speaker to do it. I wish there was a way to remotely trigger a doorbell button press for testing and other applications, but I imagine that’s actually a hardware limitation.
