I ordered the same dongle that you ordered from AliExpress, so hopefully it's good. I'll test the resistance before I plug it in though!I don't think there is a verified procedure to get to the SOH for the ZE40 models. The 22 kWh models have one, but that is of no use for you. Better wait for the dongle. Off topic: I assume you ordered a KONNWEI. Please do check the latest blogposts on (SSP) http://canze.fish.lu to ensure you can filter out / fix a faulty batch.
