Teslas dont have a bi directional charge port so if the question is "work on a tesla" the answer is "no"
Thanks for posting that. If I had the schematic I could likely go through it and figure out what was going on, I don't have the skill to reverse engineer a board like that. The issue I see with trying to back-feed the charge port with AC is it would only allow for V2G operation, it would not be able to do V2H if the grid was down. There are safety requirements for an interlock to make sure the grid is disconnected before it can supply the house if the grid is down. This is why most solar systems can't power the house is the grid is down. To setup the wall connector to allow it would complicate the install of the wall connector.I am not technical at all. Sometime in the past 1.5 years, some engineer made a video stating that the model 3 chargeport was bi directional. Then another engineer did a teardown and said the first one was wrong, and the first one agreed that "yes" I was wrong"
=============================
Just as everyone was having such fun imagining the possibilities of a V2G-enabled Tesla (which are indeed intriguing), another electrical engineer, Phil Sadow (aka Ingineerix), challenged Gaxiola’s conclusions in a video. “I don’t believe that’s the case,” says Sadow. He has identified some components on the circuit board in question as diodes, which of course allow current to flow only in one direction. Electric Revs has spoken with Gaxiola, who now admits that he may have been mistaken.

You sound like you have the knowledge to look through that info so figured I would post it for you.
A couple of points above that pare presented as facts are incorrect.Thanks for posting that. If I had the schematic I could likely go through it and figure out what was going on, I don't have the skill to reverse engineer a board like that.

The device the OP linked would not be using the PCS the video is talking about. DC fast charging bypasses it by connecting the HV DC bus to the charge port. I haven't found a schematic or wiring diagram for it but from what I can tell Tesla is using mechanical contactors to connect the charge port to the HV DC bus when using DC fast chargers. So while it is still possible for Tesla to turn them off if it senses current flowing the wrong way.
I should look into the communications standards used by the various charge standards. This wouldn't be too difficult to test, just need to spoof the data link commands to say I'm connected to a DC fast charger and see if I have HV DC at the charge port pins. Issue is I much prefer to work with low voltage systems normally under 12V. Although I would still need to test if you can actually pull power from them without it shutting off.
Wonder if this, combined with the CHADEMO adapter, would work...
