What We Do
Two Things. Both Built
for Elevators.
Smart Elevator combines a custom hardware development service with a ready operations platform, both engineered specifically for elevator control systems. One engagement. Two capabilities your product line gets.
We Design and Build the IoT Hardware for Your Elevators
Every elevator controller is different. VVVF drives, relay panels, proprietary OEM boards. We map your controller systems, design custom IoT hardware that interfaces with them, and write embedded firmware that decodes their protocols into structured operational data.
This is ground-up product engineering: schematic design, PCB layout, firmware architecture, prototype validation, manufacturing, and deployment support.
- Custom PCB design per controller type
- Embedded firmware written per protocol
- Fault code decoding, floor position, door state, motor load
- Edge processing and local buffering
- OTA firmware update architecture
- Hardware built for lift shaft conditions
- Production manufacturing and QC
A Cloud Platform Purpose-Built for Elevator Fleet Operations
The data the hardware captures needs a home. Our operations suite is a cloud platform designed for how elevator companies actually work: multi-site fleets, technician routing, SLA tiers, fault classification, compliance reporting, and client hierarchy.
This is an elevator operations platform that speaks the language of lift maintenance, service contracts, and fleet management.
- Real-time fleet dashboard: floor position, status, health
- Fault alerting with controller-decoded fault codes
- SLA tracking and compliance audit trail
- Maintenance scheduling and service history
- Multi-site, multi-city fleet management
- Technician assignment and dispatch workflow
- Analytics: trip frequency, door cycles, motor trends
- Exportable compliance reports
- Cloud-hosted or self-hosted deployment
What We Deliver
Custom Hardware. Custom Firmware.
Your Cloud Platform.
This is not a SaaS subscription. We engineer, manufacture, and deploy a connected elevator product that you own. Here is exactly what your team gets.
We survey your fleet and document controller types, protocols, power constraints, and site conditions. Then we design a custom PCB that interfaces with the lift controller.
Data captured per elevator:
- Floor position and direction (up/down/idle)
- Door open/close state and timing
- Fault codes with timestamps
- Motor current and load
- Call registrations and trip count
- Emergency brake state
- Last service date
- Live sensor readings
Hardware manufactured, tested, and certified by RnD Square. Batch testing, quality audits, and environmental validation included.
Custom firmware written for each hardware variant. Real-time data acquisition at the edge. Protocol translation: firmware speaks the lift controller's language and sends structured JSON to cloud.
- Written per controller type and protocol
- Local buffering: data syncs when connection returns
- OTA updates: fix bugs, add controller support remotely
- Edge logic: door open > 5 min triggers immediate alert
- Motor load > 150% flags potential binding
- Structured JSON output to cloud pipeline
We handle everything from survey to handover. Your team focuses on running the business.
- Control system survey: every lift documented
- On-site hardware installation (2-4 hours per lift)
- Firmware commissioning: paired to cloud, validated live
- Dashboard confirms floor position, fault codes, door state
- Technician training on platform and alerts
- Admin credentials, training docs, support contact
- Monthly firmware updates and new controller support
- Performance optimizations and monthly changelog
Cloud Platform
The Operations Platform
Your Team Actually Uses
Web-based monitoring and operations system built for how elevator companies work. Self-hosted or cloud-hosted. Your data, your infrastructure, your choice.
View Live DemoNo login requiredDashboard
8 KPI cards: Total Lifts, Working, Maintenance, Open Tickets, Critical Alerts, SLA at Risk, Completed Today, Active Technicians. City-wise health scores with lift counts.
Coverage Map
Multi-city lift registry. Real-time position of every lift across all sites. Green (running), yellow (warning), red (fault). Drill into any site for live status.
Elevator Fleet Registry
Full registry: Lift ID, Name, Building, City, Company, Floor/Direction, Status, Assigned Technician. Detail view: live shaft position diagram, ticket history, maintenance calendar.
SLA-Tracked Ticketing
Priority levels: Critical, High, Medium, Low. Status workflow: Open, In-Progress, Resolved, Closed. Categories: Door Fault, Motor Issue, Cable Wear, Emergency Brake, Leveling, Noise, Display Fault. Notes and activity log per ticket.
Maintenance Scheduling
Scheduled maintenance calendar with due date tracking. Blocker tracking (e.g., Part awaited). Status: Pending, In-Progress, Completed, Overdue. Assigned technicians per task.
Analytics and Reporting
Lifts by City (bar chart). Status Distribution (pie). 6-month Ticket Trends (line chart). Priority Distribution. Company SLA Performance showing compliance per OEM manufacturer.
Users and Access Control
Role-based access: Admin, Operator, Technician. Region and city assignments. Permission levels per role. Full audit trail of every action.
Company Directory

Real-Time Notifications
Emergency alerts (brake triggered), Ticket created, SLA breach, Maintenance overdue, Sensor fault, Technician updates. Unread badge. Configurable routing per alert type.
Self-hosted or cloud-hosted. Self-hosted means the entire platform runs on your infrastructure and operational data never leaves your network. Both options include encrypted data transmission, device authentication, and full audit trails.
The Problem We Solve
Elevators Generate Data.
Nobody Is Capturing It.
Every elevator controller already produces diagnostic data: fault registers, motor current, trip counts, door cycles. That data sits inside a closed panel. No one reads it until something breaks. We build the layer that captures it, interprets it, and makes it operational.
Controllers Are Proprietary
Every manufacturer's controller encodes data differently. VVVF drives, relay-based panels, and proprietary boards all use different signal structures, fault code schemas, and communication protocols. A connected elevator product needs hardware and firmware engineered for each controller variant.
Generic IoT Does Not Decode Lift Data
Off-the-shelf IoT gateways read voltage and temperature. They do not know what floor the lift is on, what fault code the controller threw, or that the door timing has drifted by 400ms over three months. Elevator data requires elevator-specific firmware.
Building IoT In-House Is Expensive and Slow
Hiring hardware engineers, firmware developers, cloud architects, and deployment specialists to build a connected elevator product takes 12 to 24 months and significant capital. Most elevator companies need a product development partner, not a permanent IoT team.
No Elevator-Specific Platform Exists
Existing CMMS and building management platforms were not designed for elevator-level data. They do not model floor position, lift trips, door cycles, or controller fault codes. The operations layer needs to be built for how elevator companies manage fleets.

What We Actually Build
Inside the Lift Panel
This is what separates a proper IoT retrofit from sticking a sensor on a machine. We engineer every layer of the stack to work with your specific elevator controllers.
Controller Signal Mapping
Before any hardware is designed, we document how your controller communicates: pin configurations, signal types, protocol format, fault code register structure, and electrical characteristics. Every hardware design starts from this map.
Custom Interface Hardware
We design the PCB that sits inside the lift panel and connects to the controller's signal outputs. Passive interface: we read data, we do not modify controller logic. Designed for electrical interference, vibration, and confined panel space.
Controller-Specific Firmware
The firmware translates controller signals into structured elevator data. Floor position, direction, door state, fault codes with context, motor current draw. Written in-house, per controller type, per protocol variant.
Edge Processing and Buffering
Signal filtering, anomaly flagging, local time-series buffering for network outages, and data compression. The cloud receives interpreted events, not raw voltage streams.
Connectivity and OTA Updates
4G/LTE cellular or Ethernet connectivity, MQTT or HTTPS transport, and a full OTA firmware update architecture. Push firmware revisions to the entire installed fleet without site visits.
Cloud Data Pipeline
Time-series ingestion, device management, data validation, alert engine, and API layer. Designed for elevator data patterns: high-frequency door cycles, intermittent fault events, periodic motor health baselines.
