I have a solar panel with a regulator (Victron Energy SmartSolar MPPT 75/15) that have a serial-port interface that i was with this library enable to read data from on a Particle Argon and the same library i also reading data from same interace on a Victron Energy BMW-712 Battery monitor but different values.
I have forked the code from a fork of the original library and then added the things i needed for the BMW-712 device and added some example code on my own fork that i also created a pull request to the repository i forked of.
Github: https://github.com/RickardPettersson/VictronVEDirectArduino
In the example code i make a JSON object of the values and then publishing it to the Particle Cloud and then i setup a Webhook for the event sending a HTTP POST to a own built API that saves the values to the database and then i now planning to make a dashboard and some historical graphs with the data.
I hope this can help someone a day.
