Metrom Trading receives every tenant's utility consumption automatically, in one platform.
LoRaWAN sensors on the tenants' meters send gas, water and electricity consumption with no site readings. Administrators have each tenant's consumption by utility and period, the basis for recharging utilities.
Business need
Metrom Trading leases production halls, offices and warehouses, sometimes with several tenants in the same building. Gas, water and electricity enter the park through a master meter and are split across each tenant's meters.
Utilities are recharged to tenants based on consumption. Consumption came from manual readings, meter by meter, then compiled for each tenant.
Result
Readings from every tenant are centralised automatically, hourly, straight from the meters. Each tenant's consumption by utility and period comes from the platform, with no site visits.
Solution delivered
- Automatic reading for three utilitiesLoRaWAN sensors on the gas, water and electricity meters. A new sensor appears in the platform with its first message and is paired with its meter using the index read at installation.
- Each tenant's consumptionFor each tenant, consumption by utility and by meter for the chosen period, compared with previous periods.
- Tenants and meters in one inventoryBuildings, tenants with their lease period and their meters. A building can have several tenants, by zone.
- Consumption by hour, day and monthFor each meter, total consumption, daily average, peak and an hourly heatmap.
- Alerts on the mapNo data from a meter for over 24 hours, battery below 15% and a magnetic field near the meter, each linked to its meter.
- Loss controlConsumption entering the park through the master meter is compared with the sum of the tenant meters, with an alert above 10%.
- Roles and historyAdministrators configure, operators consult. Changes and manual readings stay in the history.
How it works
- 01
Measurement
The sensor on the meter sends its pulses over LoRaWAN radio to the gateway in the park.
LoRaWAN
- 02
Reception
The LoRaWAN network server receives the message and publishes it for processing.
ChirpStack
- 03
Consumption calculation
The telemetry service decodes the message and stores the index, the hourly consumption and the sensor status.
- .NET and Azure SQL
- 04
Consultation
Administrators review each tenant's consumption, the map and alerts in the web application.
