I have a proof of concept up and running connecting a 100/20 MPPT to a LoraWAN node (Heltec Cubecell) using VE.direct and sending both data from MPPT to TheThingsNetwork as well as being able to control the MPPT load output from the TTN console.
Next step is to connect the TTN server to the VRM database. I tried to access https://github.com/victronenergy/lorawan-connect to get more info but it gives a 404.
Where can I find documentation on data upload to the VRM database? The VRM JSON API only talks about download.
