Try viewing the Wyze camera via TinyCam Monitor app instead of Wyze app.

That much data so fast makes it seems like video has been constantly trying to download. Notice that it is only downloads that are high, not uploads. So there is something that was installed that is trying to constantly download something else OR streaming something. It sure could be video -- so check & clear the Silk browser cache, close out any streaming video apps, etc.
If you installed Google Play on these devices (which from the screenshot it looks like you did) then something that was installed is doing this. Look at your Google Play "installed" list and sort it by Recent -- you should be able to see what was recently installed. I would recommend uninstalling anything installed on the devices since 1/24.
Also, go to the apps management preference in settings and be sure to look at the pane for all installed apps. Uninstall anything that looks sketchy (System apps or Amazon-installed apps will be undeleteable), but don't delete your Google apps if they are installed.
You might also want to install a good, free malware checker from the Amazon store. This one is a solid free version to scan your system, but you'll have to pony up for the full version to actively protect your system: https://www.amazon.com/Malwarebytes-Security-Virus-Cleaner-Anti-Malware/dp/B00GT4V5DM (note: I have no connection with this app or its publisher -- just a satisfied user).
I downloaded Qustodio and it appears that it will work in enforcing time limits for an adult profile on the Kindle Fire. I think this is what I need. The non-Premium features are sufficient for me.
Yep! Our app is now on the Amazon Appstore so search Windscribe there and you'll be able to download it.
Or you can go here: https://www.amazon.com/Windscribe-VPN/dp/B076ZYV6HQ and simply send it to your Firestick from the browser.
App lockers which require a pin or swype when trying to access apps and settings on your kindle.
