LoginIoT-based energy management for residential and commercial infrastructure
FirsThing instruments your building’s lighting and power circuits, measures what they actually draw, and cuts your energy spend — with no upfront cost and no control over your equipment.
Who we are
FirsThing builds IoT-based energy management for the buildings people actually live and work in — residential societies, co-living spaces, and commercial infrastructure. We instrument a site, measure it, and keep measuring it for as long as we bill against it.
EnergiTrack
Our flagship solution
Appliance-level visibility, measured savings, and no control over your equipment.
Appliance-level monitoring
See what every circuit draws, not just the building's total — the same per-light-type metering the product itself runs on.
Real-time consumption data
Hourly readings, not an estimate reconciled once a quarter.
Savings you can trace
Every percentage traces back to the readings and the benchmark that produced it.
No control over your equipment
The platform reads sensor and meter data — it never issues a command to switch anything off.
Up to 50% lower energy spend
Measured against a commissioned baseline, not a rule of thumb.
How it works
Step 1
Site audit
We walk the site, count the fixtures, and commission a measured baseline for each circuit.
Step 2
Automation
Energy-efficient devices go in; a meter watches the result against that baseline.
Step 3
Saving money
You pay a share of the saving the readings actually show, every month, on an invoice you can audit.
Products
Energy Track Device
The meter behind every figure on your monthly bill — installed per circuit, read hourly.
Energy Saving Device
Automated lighting control sized to cut a circuit's draw by up to 35%, verified against its own commissioned baseline.
What societies say
“Our common-area electricity bill dropped noticeably within the first billing cycle, and we can see exactly where the saving comes from.”
“No upfront cost, no hardware to manage ourselves — FirsThing installed it and we just watch the bill.”
“What won us over was that the savings are measured, not promised — we could see the readings behind the number.”
