Electrical engineer here. You can run copper..... the grounding won't be an issue. I highly suggest using ubiquity surge protectors at each end of the wire. I have several outdoor runs on my own property... lightning is your enemy...- wpiman

I said send notification regardless- and now I see when a car comes by. I don't often get great visibility at night. I noticed at night-- the RKNN plate reader doesn't read what the regular plate reader can see. RKNN left-- regular right... -

Ok. Done. I can replay the alert and see the plate JSON. However, I don't see the MQTT message when I play it. I am not sure that part fires when doing the AI overlay? I also removed the requirements for the MQTT. I hit the test button and that shows up.... -
