Not sure if this has been discussed in the existing HPWC/WC thread yet, but for the sake of discussion (and people being able to find this info afterwards) I'm opening up a new thread to discuss this. The new 80A single-phase (US) / 32A three-phase (EU) wall connector has an option to daisy chain multiple wall connectors, eventually enabling load sharing. The master unit has to be configured to the max. line power and subsequent units set to slave mode. For signaling there is a D+/D- (IN/OUT) wiring between the units, from master to slave, on to further slaves if applicable. According to an answer from Tilburg (Netherlands) this is currently pretty much "dumb" signaling, with the master telling the slave(s) what's "left". This brings me to an interesting idea to actually run the first and only wall connector in slave mode and actual tell it through D+/D- (IN) how much power it may draw, allowing for dynamic load assignment (i.e. based on tariff or solar power production. So I'd like to "simulate" a master unit. Did anyone measure the current on D+/D- (OUT) on one of the new wall connectors yet? I assume its either a simple dynamic resistor value (based on settings of master unit), similar to type-1/type-2 plug CP/PP signaling or an actual simple bus (maybe RS422?) with discrete power signaling. In either case it should be pretty trivial to simulate the signaling, turning the new wall connector into "dynamic output mode".
