ESP32 has built-in CAN support, but ESP8266 does not. So you will need some additional hardware …
Next you could use the CanSee code, but probably you will need to adjust the CAN related code …

Has anyone trief to make a CanZE dongle using a ESP-8266. Since its the ESP-32 predecessor and i have a couple of 8266’s lying around i was hoping they might work too.

In reply to Norbert Molnar. I was already thinking about building an ESP32-based dongle and doing something like that, though probably via MQTT. Once the code is available and I have the dongle up and running, I might take a stab at it. That OpenEVSE use case is also something I was thinking of. Additionally you could emulate plug-and-charge as supported in CCS: Disable the EVSE by default, enable it when the dongle shows up on the network and starts sending updates. And of course making nice graphs is also a good reason.

In reply to Norbert Molnar. Thank you! It is not doing any http now, just accepting commands over serial-over-bluetooth. But if course we will open-source the code when it is somewhat stable. Once telnet-over-WiFi is in there (also needed for iOS), you can start thinking about querying the car over WiFi, or even pushing data. But for that, code contributors are needed ;-)

Wooow…
Great idea!!!
I definitely need one!
It would be a very very nice thing, if it could send the Zoe data to home automation systems directly over HTTP. Like OpenHAB, EmonCMS, Node-Red etc.
An OpenEVSE integration where the charge-end battery percentage limit would be able to set… hmmm…
