Re: Zombieverter / leaf gen 2 newbee questions
Do you plan to have isolation between the CAN and the shunt terminals?

Re: First-Time Config of FOCCI And CCS1 vehicle charging
Great. In case you are charging (or run into trouble) it would be nice to provide a logfile, and the charger type if possible.

Re: Use ESP32 Web interface also as GVRET CAN device?
Using the bus number 3 the transmitting works. This number is also shown in the main window. Not sure why it is number 3, but at least it works.

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)
One topic to improve in pyPLC, maybe this improves the Tesla behavior: We are sending in the PreChargeRes "EVSEStatusCode_text": "EVSE_NotReady". The alpitronic and the supercharger are sending "EVSEStatusCode_text": "EVSE_Ready" [Edit] Pushed the fix: https:/...

Re: Use ESP32 Web interface also as GVRET CAN device?
Just noticed, that the transmit path of WifiCAN has a problem. The transmit messages, which I configure in SavvyCAN are not physically on the bus. Investigation is ongoing.

Re: MLBEvo DBC & LIN Files
Not sure I got it right. You moved the Instruments using vcds and recorded the CAN Düring this? And then play back this recording? This does not help. The vcds uses diagnostic commands (uds on isotp), but you want plain CAN in the car.

Re: QCA7000 Foccci+Clara User thread
Ok, at least the results are stable, that's a good basis for finding the issue. There are two indications, that something with the wiring is wrong: - The CP PWM is reported with 0%. This shows that either the CP is not wired to the charger, or the charger does not provide the PWM at all. - The cable...

Re: First-Time Config of FOCCI And CCS1 vehicle charging
The 0% CP duty is clearly pointing to an error, either of the charger, or of the wiring. First point is to take a multimeter, and measure on the unconnected charger whether there are 12V between CP and PE. Second, check whether the CP of the inlet is connected to the CP pin of foccci. Third, with re...

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)
Physically this exacty is the case. You can charge and discharge. The only blocker may be the software of the car, which could have a supervision that stops the thing. Some results are mentioned above in the thread, the MG is showing how great it could work.

Re: First-Time Config of FOCCI And CCS1 vehicle charging
Looks like some good progress. Next steps from my point of view: 1. Find a working serial-to-usb, to get a log file. This would help a lot to understand what is going on. 2. I propose to by a cheap STlink adapter for flashing new software. Flashing via the web interface works often, but sometimes cr...

Re: Drawing power out of CCS port (V2x, inverse charging, bidirectional CCS)
Exactly. If the hybrid solar inverter has a battery voltage range of lets say 200 to 450V, it perfectly matches to a car battery. Somebody uses this here: https://www.goingelectric.de/forum/viewtopic.php?p=2193381#p2193381 He uses an inverter which allows to set the battery type "lead acid"...

Re: Advice on charger for vag batteries
The theory says, that it is not a good idea to charge cells which went below a certain voltage thresholds. Because at low voltage, chemical things happen which cannot be reverted (https://electronics.stackexchange.com/questions/219222/is-draining-a-li-ion-to-2-5-v-harmful-to-a-li-ion-cell) So if the...

Re: Going from 4WD to 2WD with the touch of a button, what is the correct approach
Does it make a difference in consumption to run in the one motor in neutral? I understand, some cars have a mechanical clutch to decouple the motor if not used.

Re: Use ESP32 Web interface also as GVRET CAN device?
No. A blocker on the PC would not prevent the esp from connecting your router. Are you sure your router provides a 2.4GHz wifi, not only 5GHz? Is the router near? Are you sure the wifi name and password is the same as the router expects?

Tested two Tesla Model Y - thanks to the great people in the Linux day in Augsburg! They stop at the PreCharge. Most likely it expects a physical voltage on the port during the PreCharge.

Re: Use ESP32 Web interface also as GVRET CAN device?
This is normal. With pin 37 high, the device is a "Station", it does not publish an own wifi network. It will try to connect your home network, so it does not appear in a wifi list. The only relevant thing is that you provided the right name and password in the credentials file.
