DBus_mqtt not all services available

I'm relatively new to MQTT, never had to use it before. But wanted to get some information about my solar charger and inverter out. I'm running VenusOS 2.84 on a RaspberryPi, Multiplus Inverter connected via MK3 interface, SmartSolar 150|35 connected via VE.Direct USB interface. If I ssh into the Pi and run dbus_spy I get this:

But connecting to the MQTT broker shows this:

Vebus, system, settings, are all available, but not the solarcharger.

Is this expected behaviour? What can I do to get the solar charger info directly? I want to get the panel voltage and the charger state (Bulk/Abs/Float) - is this possible?

Thanks!

Martin

Hi,

Are you aware of the the part about the keep-alive on the following page: https://github.com/victronenergy/dbus-mqtt/blob/master/README.md ?

Without the general keep-alive or a keep-alive specifically for the solar topics, venus will not publish to these topics.

Kind regards,

Thiemo van Engelen

I was sure that didn't work before, but I've just got back to the installation and it has. So I must have been doing something wrong before! Thanks for your help.
