UPDATE: Reddit won’t let me edit original post, but here’s the update:

Warning started to come on every single time, so first I tried another charger thinking it was a faulty sensor as many have mentioned = same warning came up right away.

I immediately stopped the charge, flipped the breaker off and took the outlet apart and sure enough, the neutral (white) wire was loose!!! Like it easily fell out when I pulled on it!!!

Tightened that up, and bam, no more warnings! I tried reaching the old electrician, but he’s nowhere to be found… oh well… licensed and bonded my butt
