Wall connector and Leviton dimmer switches?

Wall connector and Leviton dimmer switches?

I've been experiencing some wierd dimmer switch issues with Leviton 3 way light switches and the Tessla wall connector. When our model 3 is charging ALL of our Leviton three way dimmer switches in our house become completely unresponsive to on off or dimming. However... once the charging is stopped they once again start working. Our wall connector is currently on a dedicated 60 amp circuit drawing 48/48 amps while charging... I was going to try our charger at a lower draw to see what happens.

Anyone seen this kind of behavior before?

I’ve heard of things going wonky when they share the same grounding point as your Tesla but usually its the charger that refuses to work, not the appliance.

One possible cause is a lack of grounding on the dimmers. Often older houses (30+ years old) have no grounding in the light switch boxes. People add an electronic dimmer that really requires that ground (for shielding/safety) to a box that has no ground. Things can go wonky from there. Anyway, doesn't solve it, but if the ground is missing, it may not be solvable. Some dimmers also require continuous power to work reliably, and again, many houses are not wired this way. Ideally, in the switch box, you have a ground, neutral, hot and hot to the light (4 wires) going to the dimmer.

I expect the HPWC to be wired correctly, as a missing ground should immediately give a fault and no charging is provided.

Are the dimmers also remote controlled or connected to a remote controlled ceiling fan?
I have x10 wall switches and if the microwave is on they dont work.
Something to do with a frequency interference in the line.
