First, I would like to thank everyone for backing this project! Production is scheduled to start next week and, with some luck, the first batch of 150 units will be delivered before November. Keep an eye out for more updates in the coming weeks!

I’ve received multiple emails from users requesting WiCAN integration with Home Assistant and I think that’s a wonderful idea! It would unlock many interesting applications from displaying data from a car’s CAN bus to even interfacing with sensors or gadgets that have CAN connectivity. For now, I’m still unsure of what is the best way to do this. But I think MQTT is the way to go, because it wouldn’t be limited to Home assistant; it could also integrate with other platforms. This integration would also allow streaming CAN bus data over the internet, not just local WiFi.

Another cool integration that’s been mentioned is implementing the OBD2 protocol. The device configuration webpage would need to be extended to allow the user to select the desired PIDs. Then WiCAN would request each PID at a preset time interval and publish the response to the broker or, if WiFi was not available, it would store the latest value and forward it when there’s a WiFi connection available.

I would love to hear your thoughts on these topics, we have an open issue on GitHub where you can share your ideas and suggestions. Please let us know!
