How to initialize polling of several messages in Docker Compose

[freerkvenhuizen]

Hi,

I am working on setting up the following chain: ebusd -> mosquitto -> telegraf -> influxdb using docker-compose.
Currently the entire chain seems to be working as expected, but there is 1 thing I still have to do manually which I would like to automate somehow.

After initializing ebusd I have to manually use Mosquitto to enable polling of the parameters I'm interested in using (for example) the following command: docker container exec mosquitto mosquitto_pub -t 'ebusd/700/z1RoomTemp/get' -m '?3'
As far as I understand, this command tells ebusd to enable polling for this message, which indeed works; I nicely see the data flowing into the database at a regular interval.

I would however like to add this initialization somewhere in my code such that ebusd automatically knows which messages to poll. How to do this?

I would suggest that you clone the ebusd-configuration repository (https://github.com/john30/ebusd-configuration) to a local directory and change the message type from "r" to "r1-r9" (according to the poll priority needed) for all values you want to poll regularly (refer to message definition). The parameter --pollinterval=SEC should also be set!
And you have to link that configuration volume into your docker container and add the corresponding --configpath=path/to/your/config option to your command parameters.

So you don't need to do that manually via MQTT.

Awesome, that sounds exactly what I'm looking for! Thanks!

the MQTT integration settings are capable of adjusting poll priority of messages matching filter criteria, see here and here
