Metering and grid data

Almost every energy figure in Properate starts here. There are two quite different ways consumption reaches us, and knowing which one your building uses explains most questions about timing and accuracy.

Settlement data comes from the national metering hub — the same figures your energy supplier invoices from. It is authoritative but arrives the day after.

Live data comes from a reader fitted to the meter itself. It is available within minutes, which is what makes power-peak monitoring, alarms on sudden load, and energy flexing possible at all.

Many buildings have both: the hub for correct monthly totals, a live reader for operations.

National metering hubs

• Elhub — Norway's central hub for metering data. Gives hourly consumption for each of your metering points with no equipment installed at all. Norway is moving to 15-minute values, and Properate follows that resolution as it becomes available.
  

• Fingrid — the equivalent for Finnish buildings.
  

What is needed from you: authorisation for the metering points you want read. This is an administrative step, not a technical one — you confirm that Properate may collect data for those meters. Support will tell you which metering point IDs are missing.

Reading the meter directly (HAN port)

Norwegian smart meters have a HAN port: a physical socket that streams consumption as it happens. Fit a small reader to it and Properate gets a live figure instead of waiting for tomorrow.

• AMS reader — a reader on the HAN port, delivering a continuous stream of consumption and power.
  

• Tibber — where a Tibber device is already fitted to the HAN port, Properate can read through it rather than installing a second reader.
  

What is needed from you: the HAN port has to be opened by your grid company (free, but you must ask), and a reader physically installed. Both are usually arranged as part of onboarding.

Worth knowing: if a HAN port is inactive for a period, consumption for that period reads low. This matters most for energy flexing, where the baseline is what your delivery is measured against — a baseline calculated across an inactive stretch understates it. If historical consumption looks lower than you expect, check HAN port coverage before concluding the building really used less.

Heat, water and cooling meters

These are rarely electrical meters and rarely reachable over the internet on their own, so they are collected through a gateway in the building.

• Elvaco — heat, cooling, water and electricity meters collected through an Elvaco gateway and its cloud service.
  

• Elvaco via file delivery — an alternative route where the gateway sends readings directly to Properate. This covers a wider range of gateway models, including older ones.
  

• M-Bus router — reads M-Bus meters through a router on the building's network. M-Bus is the most common protocol for heat and water meters in Norwegian buildings, so this is often the answer for a building with plenty of meters and no data.
  

• ICMeter — a Danish supplier of room sensors and metering.
  

Electricity prices

• ENTSO-E — day-ahead electricity prices for every European price area. Nothing is needed from you; it is available for all buildings.
  

Prices are what turn kWh into kroner in reports, and what price-driven automations act on — for example shifting heating away from the most expensive hours.

How the meters fit together

A building usually has a main meter and a number of sub-meters. Properate arranges them into an energy hierarchy, so that a sub-meter is understood as part of a larger total rather than as a separate number to be added by hand. This is what lets you drill from the building's total into the systems behind it without double counting.

If the figures look wrong

• Today is missing. Expected. Settlement data arrives the following day, so the latest date you can select is yesterday.
  

• A value is negative. Properate warns when it sees negative consumption. It is almost always a metering fault rather than real production, so check the meter rather than the graph.
  

• Two buildings share one meter. Consumption is reported where the meter is. If one meter covers more than one address, ask support to make that explicit in the building name so nobody reads the figure as belonging to a single address.
  

• A meter has gone quiet. Hover a value to see when the last datapoint arrived. For gateway-based meters, a quiet meter usually means the gateway has lost contact rather than that the meter has failed.
  

Adding a meter

Contact support with the make and model. Most meters can be connected without replacing anything — the point of reading at protocol level is to reach equipment that is already installed.
