I have often asked for this to be fixed. I reported it here in a Fix-it-Friday event back in Summer 2022:
But not very many users agreed (voted) that it should be considered a priority high-impact issue compared to others.
I suspect that this is partially because a lot of people don’t notice, and for those who do, many don’t see that it would make much difference. Technically, Wyze could “hide” the SSID name broadcast like I’ve been asking them to do, but the reality is that this doesn’t actually make it more secure, it just makes everything LOOK a little more clean. It is best practice because it is not an SSID we will ever need to select to connect to manually, so it shouldn’t be showing up that way. However, even if they do hide it like we’ve been asking, it won’t change the fact that it is still broadcasting WiFi that can add to signal interference (just like every other single WiFi device does. That issue will remain.
Please do. Keep in mind that if you learn anything and report it to their Bug Bounty program, they will actually PAY you for whatever you discover. Bug Bounty: Wyze Bug Bounty - Bugcrowd On the other hand, you could share what you find here instead, but you won’t get any financial compensation for it. 
Though I would enjoy reading any findings.
We could try submitting it to Fix-It-Friday again like I tried before, though I suspect that like the last time I tried, we wouldn’t get a lot of the community to agree that it’s a high-impact priority.
As for the channel number, I am not sure they can change that. Since the Chime is connecting to the Router, it has to be using the same channel as the router. If they changed the channel, then it would stop having any internet connectivity and stop functioning.
