I had this issue and wanted to post to see if I’m alone or maybe it can help someone.
- I installed the Tesla Universal wall connector successfully.
- Used Tesla One app to commission connector, set up proper breaker, and connect the unit to WiFi successfully.
- Went to add wall connector in Tesla app and wasted an hour of my life trying to get the damn thing to work while repeatedly getting errors that the app could not connect to the wall connector. Tried every trick listed on the forum from disconnecting cellular data to putting my phone an inch from the wall connector…
- Went and got my wife’s Android phone, installed the Tesla app, logged in, and was able to add the connector to my account in 30 seconds.
