Integrating with Open Vehicle Monitoring System (OVMS)

[amotl]

Hi there,

after writing down #330, I just found @glynhudson might already be working on a respective integration with the Open Vehicle Monitoring System (OVMS) he outlined within #321.

I am deliberately opening this issue as an anchor to track the integration between both systems.

With kind regards,
Andreas.

Hi @amotl,

I've recently been using OwnTracks with OVMS which works well to record the location of the vehicle. See an example of a recent trip I made this christmas in my EV

The integration was done in quick and hacky way using OVMS V3 server logging to MQTT then using NodeRED so subscribe to the OVMS GPS MQTT topics and then publish these to owntracks recorder MQTT topics in the correct format. I'm happy to share this NodeRED flow but it's probably not the most eligant solution.

Thanks for sharing your example!

Sure, this would well resonate with what I wrote elsewhere just yesterday where I've asked @dexterbg about appropriate integration with InfluxDB and Grafana through Kotori.

Saying that, OVMS might additionally add support for Node-RED for users aiming to make their custom data and/or notification flows. daq-tools/kotori#21 (comment)

Here is my NodeRED flow:

Thanks @glynhudson! @jpmens, @ckrey, @linusg and the community will like it. On the other hand, I might be able to reuse the essence of that (ovms/emonpi/<VEHICLE-ID>/metric/v/p) to work on daq-tools/kotori#21.

@jpmens: Should we add this file [1] to the repository or put it into the documentation somehow?
