What is LegitOS
A white-label operating system for submetering businesses.
LegitOS is WiserMeter’s submetering platform for operators, utilities, property managers and real estate developers. It covers meter reading, billing, field operations, resident portals and executive reporting — as a full stack or as API-first modules. Launch in weeks, white-label ready, proven in live operations across Brazil and expanding across the Americas.
Who uses LegitOS
One platform. Take the whole chain, or plug into the one piece you need.
One piece of the chain
Already have billing or your own portal? Take only what's missing.
LegitOS is API-first. Add meter reading, field operations, or the billing engine on its own — it drops into what you already run.
See how integrations work → Platform
Every layer of your submetering operation.
From the meter in the wall to the invoice in the client's inbox — LegitOS covers the full stack.
Field
LegitField
Handles meters that can't be read remotely. Field technicians capture readings via photo or BLE directly from the app. Legacy meters, non-communicating devices, edge cases — all covered.
LegitField →Operations
LegitDesk
Integrated helpdesk for submetering operations. Manages support tickets from residents and property managers — keeping every request tracked, assigned, and resolved without leaving the platform.
Resident portal
LegitApp
Consumption history, leak alerts, and usage goals — accessible to residents and property managers directly from their phones.
LegitApp →Hardware
LegitFix & LegitMov
Two ways to get data off the meter: LegitFix as an always-on fixed concentrator, LegitMov as a mobile receiver for sites with no fixed install. Both HaaS, both read wMBus/BLE, both stream straight into LegitOS.
LegitFix → LegitMov →Billing
Billing Engine
Automated billing per unit, per cycle. Complex billing rules, exceptions, partial readings, proration — all handled without manual intervention.
