question

Hello,

ok, sorry now it works !

it was a wrong formatted message what i send.

found in /var/log/dbus-mqtt/current:

@400000006184e10420c219cc Traceback (most recent call last):
@400000006184e10420c3989c   File "/opt/victronenergy/dbus-mqtt/dbus_mqtt.py", line 136, in _on_message

@400000006184e10420d03714 ValueError: No JSON object could be decoded

With correct format of the setting it works:

W/_________/settings/0/Settings/CGwacs/BatteryLife/MinimumSocLimit
{ "value": 50 }

the spaces between the brackets are significant !

regards Yves.

Hi Yves,

i want to achieve the same as you did. Here iam using OpenHab to integrate my Victron with Mqtt.

Setting the value is working like you did but after a couple of seconds it set back to the previous value. So i can see the change of the value in the VRM Portal but its not consistend..

Do you have any hints about that ?
