Hi,
is there a way to get historic data (json array) from mqtt broker ?
The goal is to have multiple timestamped data in the same transaction.
I'm using JSON schema A but cannot figure out how to format json array message from device
Sparkplug B Driver seems a lot more complicated.Does it support this features ?
Thanks
