Sameie Leangen Løkka - a 143-unit residential co-op in Trondheim, Norway.
Trondheim, Norway · Housing co-op
Per-apartment billing, without spreadsheets.
Sameie Leangen Løkka is a 143-unit residential co-op in Trondheim. Every unit has an ultrasonic water meter and a heat meter; LoRaWAN carries the readings to Divako, where shared costs are split by the rules the board signed off on, and finished invoices roll out automatically. Residents see their own consumption in an app.

At a glance
The shape of the rollout
A full sub-metering stack for a single co-op: meters, network, gateway, parsing, settlement and resident portal.
Network
LoRaWAN on a Multitech Conduit 200 IP67 gateway - one device covers the whole building stock.
Meters
Apator Ultrimis ultrasonic water meters (no moving parts) and Engelmann SensoStar U heat / energy meters in every unit.
Settlement
Heating, hot water and common-area costs split proportionally; invoices generated automatically; resident portal on iOS and Android.
The challenge
Fair billing across 143 apartments - without an argument at the AGM.
Anyone who has sat on a housing co-op board knows the cost-split conversation. A shared boiler heats every apartment to different degrees. A shared hot-water riser doesn't care which unit takes the long shower. Without per-unit metering, costs get apportioned by square metre - which is simple and slightly unfair to almost everyone.
Leangen Løkka wanted accurate per-unit consumption for both water and heat, on a single platform, that could read meters automatically and turn the numbers into the right invoice for each household. Without three vendors. Without a spreadsheet. Without a monthly argument.
- 143 units, each needing water and heat measured individually
- Cost distribution rules that hold up to scrutiny at the AGM
- Self-service portal so residents can see what they're paying for
- One vendor on one contract - not a stack of suppliers
What we built
Ultrasonic water, heat meters, one gateway, one platform.
Every unit has an Apator Ultrimis ultrasonic water meter and an Engelmann SensoStar U heat / energy meter. Both transmit over LoRaWAN to a single Multitech Conduit 200 IP67 gateway - one piece of hardware for the whole building stock. Divako parses every payload, validates the readings, and feeds the Settlement module that runs the per-apartment cost split.
Heating, hot water and common-area usage are apportioned by the rules the board signed off on. Invoices are generated automatically. Residents log into an iOS or Android app to see their own daily and yearly consumption - and act on it. The board sees one finished invoice per cycle, not a stack of spreadsheets.
- Apator Ultrimis ultrasonic water meters - no moving parts, no maintenance drag
- Engelmann SensoStar U heat / energy meters per unit
- Multitech Conduit 200 (LoRaWAN, IP67) - one gateway, whole building
- Automated cost split with rules the board controls
- Resident portal on web and mobile - daily and yearly comparisons
Outcomes
What changed for the board and the residents
One invoice, not 143 spreadsheets
The board signs off on one finished cycle. Settlement does the maths. No manual hand-offs, no follow-up corrections.
Pay for what you use
Per-unit metering makes the cost split fair on its own terms. Residents who use less pay less - and can see why in the app.
Zero manual readings
Ultrasonic meters have no moving parts; LoRaWAN sends the numbers automatically. Nobody knocks on apartment doors any more.
One vendor, one contract
Meters, gateway, network and billing - a single bill of materials and a single point of support, not three.
"Three vendors replaced by one. Ultrasonic meters, encrypted data straight to the cloud, and the cost split done for us - residents see their use in the app while the board just sees the right invoice land."
