New build
S1 DirectSDM230-M
Make automated collection part of handover. Install, commission and map every unit during construction.
Fair, transparent sub-metering for modern buildings
Automated collection for new builds. Lower-disruption upgrades for existing properties. One operating view across every unit — built for build-to-rent developers, apartment buildings and property operators.
The Problem
Someone walks the building, reads every meter, re-types the numbers. Every billing period, forever.
Equal splits and estimated reads invite arguments. Tenants want to pay for what they actually used.
A dead meter can sit silent for weeks — and the gap only surfaces at reconciliation time.
01 · The Line-up
Start with the building. Then choose the least disruptive route.

New build
Make automated collection part of handover. Install, commission and map every unit during construction.

Retrofit · compact CT
A compact CT module that reduces switchboard and main-circuit disruption in existing buildings.

Retrofit · LoRaWAN
Avoid long data-cable runs in difficult sites. Wireless LoRaWAN back to the gateway.
02 · Project Routes
01 · New build
Install, commission and map every unit during construction so the operating team starts with clean data at handover.
S1 Direct
One standard route
02 · Retrofit
Both retrofit routes use split-core CTs. The site decides whether a data cable is practical.
Cable is practical
S1 Compact
No conduit / high cost
S1 LoRa CT
Split-core CTs reduce main-circuit work. They do not replace electrical safety procedures.

04 · What Changes
The result is a building that is no longer tied to repetitive manual processes.
A clear product route for every project stage, chosen to minimise electrical work.
Automatic collection replaces repeated site visits and manual re-entry.
Tenant-level data replaces equal electricity-cost splitting and estimated bills.
Scale units without scaling repetitive labour at the same rate.
Privacy & Security
Data is held in a protected cloud environment and encrypted in transit, with role-based access for your operating team.
Guidance on New Zealand metering compliance is in progress ahead of commercial deployment. We don’t claim certifications we haven’t verified.
We use one building to confirm the product route, installation impact, data quality and operating workflow under real site conditions. We’re running this now — honestly, as a pilot, not dressed up as a case study.
FAQ
No. Sub-metering sits downstream of the main connection and measures unit-level usage. Your existing utility metering and retailer arrangements stay as they are.
Both retrofit routes use split-core CTs, which clamp around existing cables and avoid rewiring main circuits. Installation is scheduled around the site, and the LoRaWAN option removes the need for long data-cable runs entirely.
The platform raises an alert for the specific device, tied to its unit number, so the issue is visible within the day — not discovered weeks later at reconciliation.
Yes. Tenant-level usage data can be exported to feed your billing and reconciliation process, replacing manual reads and re-entry.
Data is held in a protected cloud environment, encrypted in transit, with role-based access for your operating team. Guidance on metering compliance is in progress ahead of commercial deployment.
One building: site survey, design and budget, a small pilot under real conditions, then a standardised route you can replicate across the portfolio.
