I am using a Node-Red addon as part of on a Victron Venus installation on my boat’s Cerbo GX, and it is older than the version I use on Hass.
I will have to send the source data (from a Victron Device) to my Hass instance and run the flow on. that device. I will then have to send the results back to my Cerbo GX.
This should work but adds a possible failure point as they are different devices.
