VE.Direct to MQTT gateway using ESP32

This is actually an annoucement.

I could not find a VE.Direct to MQTT gateway that is using WiFi, so I created one.

It only uses VE.Direct ASCII mode, listens to the device and sends received blocks to MQTT

My two MPPT75/15 devices are great and I wanted to integrate them in my IOBroker setup using a MQTT gateway, only for monitoring purpose.

You can find the code on GitHub. Look for:

VE.Direct2MQTT

This is great!!! I will build it as soon as possible. I’ve just downloaded the “white books”, but I guess I don’t need them now.

Thank you so much for sharing your project.

Also built a service in Kotlin to read the data of any VE.Direct device (that's documented in the official VE.Direct Text protocol PDF) and push it to my monitoring system.

Everything OSS, currently lacking setup instructions and proper READMEs, but will eventually be available.

A first release-version of the client will be available most probably in a few days, but feel free to check out the code at https://github.com/logreposit/ve-direct-reader-service. Feedback very appreciated!


Cheers,
Dom
