Investigate a reported problem with context
A low temperature is a starting point, not a diagnosis. Current readings and historical trends help an operator examine what happened before a complaint, which equipment was involved, and whether different measurements tell the same story.
In the residential pilot, a heat-pump outlet temperature can be compared with measurements from a PT1000 sensor and a heat meter. Flow-rate trends also helped narrow down a circulation-pump problem before a repair technician attended.

- Alerts linked to the relevant measurements
- Historical trends for a more targeted investigation
Coordinate capacity with measured demand
The pilot contains twelve 16 kW heat pumps serving heating, cooling, and domestic hot water. Metraon uses measured demand to determine how many connected heat pumps should operate. Defined equipment priorities and fallback settings form part of the agreed control configuration.
Cloud control logic sends commands through MQTT to the local gateway, which interfaces with the equipment through supported Modbus connections and I/O relays. A command or delivery acknowledgement is not proof that the physical equipment reached the intended state; relevant measurements and feedback must be checked.
A documented remote response
After a reported hot-water supply problem at the 52-apartment pilot, the operator checked tank temperatures and heating-plant state, then enabled additional heat pumps. The inspection of the state and the remote adjustment were completed in under 30 minutes, without an initial site visit.
This describes a specific incident. It does not establish a general response-time commitment, the time taken to restore hot-water temperature, or verified energy savings. The full case study explains the system and its current limits.
Begin with monitoring; agree control separately
Monitoring can be scoped without enabling remote commands. Before introducing control, review equipment interfaces, operating priorities, fallback behavior, network dependencies, and installation responsibilities with the operator.
Bring a plant schematic, equipment list, and a concrete operational question. Compatibility and the control scope are established for each building; remote monitoring does not replace necessary on-site diagnosis or repair.
