Project team
A building operator planning submeter visibility before connecting to a BMS or cloud system.
Challenge
Meter readings need to be organized by floor and equipment group, with an interface that matches the chosen BMS or receiving platform.
Equipment in the system
Example equipment arrangement. Check compatibility and agree who handles software, PLC/SCADA programming and site installation.
Data destination
Customer platform or an agreed third-party service
Site context
- Tenant or floor-level electrical panels
- BMS or cloud integration undecided
- Data needed for reporting and load checks
Approach
- Group meters by panel and reporting requirement
- Confirm Modbus/BACnet or MQTT handoff
- Keep customer platform ownership explicit
Hardware plan
- DIN rail power meters
- CT sets
- RS485/BACnet gateway
- Optional cabinet sensors
Hardware reference
Product-family photos; the model and enclosure may vary.
Integration path
- RS485 meter bus
- Modbus TCP or BACnet to BMS
- MQTT option for customer cloud
Checks before rollout
- Confirm meter installation and who manages the receiving system
- Check the required BMS or cloud protocol before ordering
- Verify the readings on one panel group before adding other floors
Quote inputs
- Panel list
- Meter count and CT ratio
- BMS/cloud protocol
- Reporting interval

FAQ
How can I use this design example?
Compare the measurement points, equipment connections and site checks with your project. Send the existing devices, available power and receiving system so we can check a suitable configuration.
Can existing building meters feed a BMS or cloud system?
They can when the meter interface, register map and selected gateway match the receiving system. Confirm whether the BMS requires Modbus TCP or BACnet, or whether the cloud accepts MQTT, before ordering a gateway.
What information is needed to compare submeter configurations?
Send the panel list, meter count, wiring and CT ratio where applicable, BMS or cloud protocol and reporting interval. A pilot on one panel group can check the values and data mapping before the arrangement is repeated.
