I have 4 Cams, 1 sensor kit + additional motion sensor, and one scale. The only issue I have, which is caused by me using the RTSP firmware on the camera that hosts the sensor base, is that I can’t update the sensor base. But there only one firmware to move it to, and it disables the reset button (which I’ve never used).
I too am an early adopter if WyzeCams, getting two V2s on the first day, and being one of the first to get the Black Edition camera ordered and delivered. I got the sense kit early release as well. None of these things have given me an issue that wasn’t my own doing, poor placement, the result of a crappy WiFi environment, or similar non-Wyze caused issue.
I’m not saying it’s definitely the issue, but placement and your WiFi environment are a huge factor. In the middle of my block first-floor, I have 15-20 detectable SSIDs from other homes, if you consider each neighbor is pumping out at least 2 SSIDs. This also includes their printers that are not setup right, one neighbors chromecasts show up all the time, and then people’s phones.
I had to take my laptop and run an analyzer to see which channels are the least congested and force my WiFi router to use those. This made a world of a difference for my devices. I also spend a little bit of money for a mesh setup that has a dedicated back haul (1Gbit powerline) and things go even better.
My mom’s setup on the other hand was way worse to fix, because her ISP provided modem did not allow the WiFi to be disabled and only provided 1 SSID for Burge 2.4Ghz and 5Ghz signals, which many IoT devices do not like. Add to that she has a metal framed house and you get a bad environment to setup anything WiFi in. I tried extenders and repeaters, none of it worked well, and her cameras would drop signal all day long. We finally got them to switch out the all-in-one modem/router, and being able to actually get into the settings to change things made a difference.
Not saying your issues aren’t device based, but a lot of people in a lot of homes just don’t know how bad their wireless environment is, and blame the devices when in fact it’s not those at all.
Look for a WiFi analyzer for your phone or PC/Mac and see what’s really going on. You might be surprised to know that the channels you’re WiFi is using are the most congested ones, which can cause nothing but connection issues even with a strong signal. You can be the loudest in a hallway, but if everyone else is talking in the same hawllway at even half your volume, it’s still going to be hard for you to hear everything you need to hear.
