I’m looking for ideas , short of buying a second charger, of how to identify which car is charging and when. Ideas so far are,
-
My first idea was to change the charging current on a car to identify which is which but I’m unable t o change the current on either.
-
I was thinking of making an RFID tag that has to be scanned in order to identify and engage the charger. This one is sounding promising with a low WAF score.
-
My current idea is using esphome and a d1mini to install a reed switch next to the charge port and put a magnate on one of the cars.
Any ideas would be greatly appreciated.
