SmartShunt Support

It seems like this works pretty darn closely with Victron Energy's SmartShunt via Bluetooth. Here's the relevant output from the debug that I have going at the moment.

Any suggestions as to how I can try and help out to get it added?

Thanks!

Here's some additional resourcing about the endpoints: https://community.victronenergy.com/questions/93919/victron-bluetooth-ble-protocol-publication.html

and I found these two projects as well: https://github.com/birdie1/victron https://github.com/vvvrrooomm/victron/

As you can see, there are sone writes that are sent to the device, which fails. You probably need to send some other data to stay connected, but look at the provided resources and #7 to help understanding how the device works.

Just some spring cleaning of old issues
