Yes that is what it seems but not %100 sure though.
Way back I received a replacement bridge from Wyze.
I rebooted the cam and waited for it to show blue LED.
Connected all my senors without a problem.
A week latter I notice in the app that the FW needed an update.
Did the update and all was well.
So for me it seems you must make sure the bridge and cam is excepting each other by the indicated Solid Blue LED first.
If it does not turn a Solid Blue then press the button on the back of the Bridge.
Not sure at this step you should update the Bridge FW, yet until someone can verify this or try at your own risk.
When Solid Blue …then connect the senors.
Then updating the Bridge FW at this point need to be verified also or try at your own risk.
All in all if the above I wrote is wrong don’t quote me on it …but if I’m right please share it …
