@Jermuk, I'm working through some great UMH content!
With the attached layout, where do you separate on-prem vs off-prem?
We currently have the MQTT only version, and leaning towards having an internal db for storing client data on-prem direct from broker. Runs even if internet out. Then bridging broker back to broker at our HQ, and storing that in a database (thinking Timescale) for our multi-site dashboards / reports.
Any advice here?
