So, I know this is somewhat a new-technology conflicts with old-technology gripe, but perhaps the issue is broader than what I'm experiencing... It appears that the Tesla Mobile Connector is preventing my X-10 home auitomation stuff from working, even without the car being plugged into the TMC. I'm the happy new owner of a 2010 Roadster 2.0, #834. Been charging it (slowly) off the home 120v while waiting for a 10-30 adapter for the Mobile Connector, which arrived on Friday. Saturday afternoon I installed a second 10-30 plug in the garage (essentially making a 2-plug outlet strip, one for the dryer, one for the car). Plugged the Connector into the new outlet, and the cable into the car. (I had already told the car to limit charging to 24A before plugging it in.) Click! Whirr! All seemed fine. Later that evening I noticed that the X-10 control system in the house wasn't working. I have two controllers; lights and appliances wouldn't respond to either controller, but but the modules still worked locally. Figuring the car on 240v was too noisy (even though it wasn't actually charging by then), I unplugged the cable from car. Still no joy with the X-10s. Unplugged the TMC from the new plug, and all is working again. The dryer itself can run without affecting things, so it's not simply a matter of having a device that bridges the 240v circuit. And the car on 120v is also ok, at least on the circuit I had it on. I simply can't run the house with the TMC plugged in. Since we're apparently supposed to keep the car plugged in when at home, I either need to go back to the 120v setup (annoyingly slow, and at 15A it limits what else I can do on that circuit), or find a way to filter or isolate the TMC so that it doesn't interfere with the operation of the X-10 system. I do have access to the wiring, but messing with 240v / 30A stuff is a bit scary... A quick search didn't yield anything that appeared to fit the need. Any ideas?
