MQTT changes are reflected in MQTT Explorer but not in the Cerbo GX UI

Im not able to integrate succesfully MQTT with Home Assistant. For example, Im playing with the MaxDiscargePower. I have the next facts:

- When I modify the setting with the Cerbo UX, the changes are shown in HA really quick.

- When I modify the settings using Home Assistant MQTT, Im able to see the changes with MQTT Explorer but not in the Cerbo GX UI and for sure, the Victron doesnt not behave as expected.

This is an example with MaxDischargePower=100 with HA:

MQTT command:

Solved, thanks for your help. It was a missing configuration in the broker bridge, the W topic was missing

The command topic needs to be W/my-id/settings........ rather than R/my-id/.... when you are publishing to the venus mqtt server.

Try removing the “victron/“. I don’t believe that is necessary

or rather enable bi-directional bridge with HA.

The broker on the GX itself does not have a leading topic , like "victron"...I believe this gets introduced when bridging with the HA broker.

Either publish (W) to the GX Broker directly or enable the bridge in HA to work both ways.
