Hi Magnus,

thank you for your work!

Actually i am using the original iNet-Box, but i've been working on a solution, thats more flexible and more integrated. More flexible in terms of compatibility to other components and more integrated in terms of usability and ui. To accomplish this, i've installed a Victron Cerbo GX as kind of central point. The platform of the underlying Venus OS is quite open. Next to different kind of sensors, etc. i can connect, there is a mqtt broker on board, which i can use local, without being connected to the internet. This is a must have for me, because i have to keep an eye on the WAF ;-) Furthermore the local broker forwards his messages to the VRM Cloud, wich is the Victron cloud portal. Now i make use of it, by connecting to this central mqtt broker i.a. to get connected to my Home Assistant instance.

To get to the point: This lokal mqtt broker of the Cerbo GX device needs a kind of prefix topic for incoming messages to be excepted, for instance: 'N/49e7da53012f/system/0/...', where '49e7da53012f' is the ID of the installation.

So a topic of '_service/truma/control_status/target_temproom' won't be accepted by the broker.

My goal is to send a topic like this: '_N/49e7da53012f/system/0/service/truma/control_status/target_temproom'

Would you please advice me how to get this done?

Thanks in advance Daniel

Hi Daniel,

the installation doesn't sound easy. My WAF would fail without an internet connection to accompany it. ;-) But anyway:

You have to adjust main1.py line 46-49, but you will lose the auto-config function in HA, because it does not react if the topics look like you need it to. Can't you alternatively use the HA-mosquitto-instance?

# Change the following configs to suit your environment
S_TOPIC_1       = 'service/truma/set/'
S_TOPIC_2       = 'homeassistant/status'
Pub_Prefix      = 'service/truma/control_status/'

Hi Magnus,

thank you for your quick response. The HA mosquitto broker is not in the same network, so if i would go this way, i had to deal with vpn, etc.

So i will try to edit the lines from main1.py.

What is your solution? What kind of mqtt broker do you use in your RV?

Is there anything else I can contribute to this?
