I recently purchased a 2024 Model Y and had two Gen 3 Wall Connectors installed on 60A breakers that utilize group management and charge up to 48A. Everything works perfectly except when I set a schedule for charging to take.place at off-peak rates. When I do this, it causes a CP_a074 charging equipment communications error and does not start charging as scheduled. I have to disconnect and reconnect to start charging and this is causes my Model Y to no longer show parked in the app but instead a generic Electric Vehicle. The app also then reports the Model Y as a non-Tesla vehicle. The fix is to simply switch the breakers off and back on which then fixes the issue but is a tad annoying.
Does anyone know why this might be happening? The car and the wall connectors are all brand new. The install was done professionally, using the correct gauge wiring, breakers, etc.
I've scheduled a mobile tech to visit in a couple of weeks but seeing if anyone else has had this issue.
