Constant Blue LED on AG 1

Had a prebuilt unit that had both sensors die but AG sent me a new unit out which works great.

I ended buying the sensors individually and replacing the faulty ones in the aforementioned faulty unit and they’re working fine, but I have a persistent blue light on the monitor that I don’t know how to turn off.

Any advice from you legends?

Since there’s no responses yet, I’ll just quickly say I have tried re-flashing it multiple times and wiping it completely but no luck.

Do you have the serial number registered on the Dashboard?

I assume you are talking about the far left LED?

This doesn’t cover a White LED which I see frequently, or Blue as you described
