Spark simulation service

Dear Team,

I am trying to run a spark simulation on a second raspberry pi. I am hoping to be able to use this to build/experiment with a Herms setup, which I am hoping to move over too in the future.

I have followed the instruction to install Brewblox on the new RPi, but when I run the command to install the Spark simulation service, I receive the following information/error.

"pi@raspberrypi:~/brewblox $ brewblox-ctl add-spark --name spark-one --force --simulation
brewblox-ctl requires extensions that match your Brewblox release. Do you want to download them now? [Press ENTER for default value ‘Yes’]

SHELL docker rm ctl-lib
SHELL docker pull brewblox/brewblox-ctl-lib:edge

Am I missing something, or does this have to be installed along side an existing Spark controller.

Grateful for any advice or pointers to correct process.



you’ll want to run brewblox-ctl setup first, and then the add-spark command. Brewblox as system is exactly the same, regardless of whether you are using simulation sparks or real ones.

Thanks. Sorry for the trouble. Makes sense now.
