vedirect changing settings of the mppt device

i can see on dbus there are settings for mppt solar chargers like status where i can remotely turn on and off by setting this value but i couldn't find the settings for other parameters that can be set from the victronconnect app. is there any documentation or hint where to look ? an example is how can i change max charge current or absortion voltage ?

U can change ve.direct devices via victron connect with „vrm“ instead of „local“ in the app.

Hi @ers

For the settings communication between VictronConnect and the product we have the so called vreglink dbus interface. This interface is descibed here https://github.com/victronenergy/venus/wiki/dbus-api under the paragraph "The VregLink Interface".

Kind regards,

thanks I can read and write vregs via dbus now.


one more question I assume vrm devices part of the victron connect app talks to vregs here too but which service/package is used for victron connect vrm control ? I used victron packages indiviually not on venus os itself therefore I can reach vrm and send data but how can I enable two way communication so that I can see vrm devices on victron connect app under vrm section ?

Hi @ers

For the communication through VRM between VictronConnect and a venus device, there are 2 services running on the venus device. The first is dbus-mqtt (https://github.com/victronenergy/dbus-mqtt) and the second is mqtt-rpc.

Kind regards,
