Welcome to the Forums
You will first need to subscribe to be a Beta Tester. Go here for that: Become a Beta Tester – Wyze and install the Beta App.
Once loaded:
- start the app and go to Account tab
- Tap on the About Menu Choice
- Tap on Beta Program
- Tap Edit in the top Right
- Then Select the Devices you want the Beta Firmware for, or select all. I select all.
Once this is done you can go back to the Account Tab and tap on Firmware Update and see what is availabale.
You should note that some times you will need to go to the Device and check via the Device directly.
