SOTL – the System of Things Learning
Intelligent IoT Data Sensor Management & Analytics
SOTL helps turn sensor data into analytics
Datahoist’s System of Things Learning (SOTL) is a full-stack predictive maintenance platform for elevators that transforms hardware motion data into clear, actionable reporting. By pairing compact on-car sensors with localized edge processing and continuous machine learning, SOTL tracks individual unit performance against its own operational baseline. Whether managing a single building or a multi-site fleet, SOTL delivers tailored diagnostic depth for service technicians and clear health metrics for building owners to streamline dispatching and protect equipment investments.
How SOTL Works
From the physical sensor on the elevator car to the clear report on your desk, SOTL connects machine motion to operational decisions. Endpoint hardware like the SOTL5mini, SOTL5, and SOTL6 captures real-time run and door performance to establish a unique baseline for every unit in your fleet. By analyzing trends locally and routing encrypted updates back to cloud management, SOTL ensures dispatchers and building owners get early, reliable warnings before minor mechanical drift turns into tenant downtime.
01 - Sense
On The Car (device)
Door cycles, car runs, vibration, and motion class — captured where the equipment moves.
02 · Gateway
SOTL Gateway
Analysis on the unit. Store-and-forward if power or network drops. Then it catches up.
03 · Link
Secured Identity
Each unit has its own cryptographic identity. It only calls out — nothing to open on the building network.
04 · Fleet

This unit’s own baseline. Building overview, six-month trends, twelve-month judgment.

Inside SOTL
SOTL bridges the gap between raw machine motion and clear, actionable business metrics. By combining continuous on-unit monitoring with cryptographic device security and automated trend analysis, the system delivers deep diagnostic visibility for service technicians while giving building owners simple, reliable equipment health reports.
SOTL DM
Device Management
The cloud record for every unit: online or offline, in service or out of service, config with an audit trail.
- Factory-enrolled units appear in the fleet on first power-up at the site
- Sensors attach themselves to that car’s record
- Production, training, and diagnostic modes — lab experiments expire so they cannot leak into the fleet
- Updates, reboots, and diagnostics on units that have no inbound ports
- One reports UI for SOTL5mini and earlier SOTL devices
SOTL Gateway
Resiliant Edge Runtime
The SOTL software on the car, escalator or other ‘in-motion’ device is built for resiliance. Power loss is becoming more of a normal event and the SOTL system helps ensure your truck rolls are for hardware, not for software.
- Keeps motion data through network and power loss, then catches up
- Reduces motion and vibration on the unit — the cloud gets events and summaries
- Updates itself and attached sensor firmware without a site visit
- Serial on the box matches the fleet record
SOTL Analytics
Learning Your Devices
The SOTL system ensures that analytics are device specific and don’t rely on generic, pre-determined thresholds. So, a slow door warning is specific to a particular door and is measured against that door’s history – A slow door is slow this door!
- Door open vs close, run vs relevel, incomplete cycles
- Expected use vs actual duty
- Weekly trend engine for fleet reporting
- Owner view and servicer view: same verdict, more diagnostic depth for the mechanic
Built for Your Building’s Network
Security is how the unit gets on a car without an IT project.
Issued Identity
Every unit has a unique cryptographic identity. The cloud only talks to devices Datahoist issued.
Outbound Only
Field units call out. No inbound ports to open. Works behind firewalls and carrier networks.
Signed Software
Units run releases Datahoist signed. No default passwords on production hardware.
Cellular or Wi-Fi
A unit comes online where there is a cellular signal or a building wireless network.
Reports You Can Act On
Same motion data, three depths of understanding and context. Owners subscribe to a layer of analysis specific to their high level business needs, while service companies see the diagnostic detail view that sits under it and provides them the detail they need.
Building Overview
What needs attention this week?
In service vs out of service vs sensor offline. Door cycles, incomplete closes, and a health badge per unit — this unit against its own baseline.
6-Month Trends
Which units are getting worse, how fast, which side?
Open vs close, up vs down. Lead time before a tenant-visible fault. Rank the fleet by evidence instead of by rotation.
12-Month Judgment
Is it seasonal? Did the last visit work? Where is the duty going?
Seasonality, maintenance verification, and usage ranking — the numbers that survive into budgeting and modernization talks.
