I got 28.3.1 last week, and today was the first time I ever saw this warning notice. I wonder how new of a warning it is. I had my 3 charging on its usual 240 volts 32 amps, and I had it on for about 2 hours. I went out to the car to get something, and noticed on the screen that it was only charging at 16 amps and it had this on the screen. The charge plug wasn't hot at all, but the box on the charging cable was warm all over.
Maybe Tesla changed the temperature limits for considering it to be overheating? I've been using this EVSE for 15 months and it has always worked fine. I've charged in warmer weather, so that shouldn't be the cause.
