UONO™
YOU ONLY NEED ONE
Universal Industrial IoT Gateway
One panel-mount device that reads the meters, sensors and machines your plant already has, shows the values on the panel, and sends them to the cloud over WiFi or 4G.
Every common industrial input, in one box
UONO replaces a rack of converters and a separate gateway. It fits the same cut-out as any panel instrument, so it goes into existing panels without new enclosures.
1 × RS-485 Modbus RTU
Master for energy meters, PLCs, drives and controllers: several devices on one line, with ready-made meter presets.
2 × 4–20 mA
Current inputs for pressure, level, flow and other process transmitters, scaled to engineering units.
2 × 0–5 / 0–10 V
Voltage inputs for transmitters and analog outputs from existing equipment.
1 × RTD (PT100 / PT1000)
Direct temperature measurement, no separate transmitter needed.
4 × digital inputs
Machine run status, trips, door switches and alarm contacts.
1.8″ colour display
Live values, connection status and faults, right on the panel door.
WiFi first. 4G when it matters.
UONO uses the plant’s WiFi and switches to 4G LTE on its own when WiFi or the internet is down, then returns to WiFi when it recovers. Your data keeps flowing either way.
- No programming. UONO hosts its own setup page: add meters, pick presets and connect to the cloud from a phone.
- Over-the-air updates. New firmware reaches devices in the field without a site visit.
- Built to stay online. Watchdogs and automatic recovery after network or power problems.
- Fits your systems. Cloud platforms, SCADA and enterprise software over open protocols.

Where UONO is used
Energy monitoring
kW, kWh, power factor and voltage from panel meters for audits and cost control.
Water & pumping
Tank level, flow and pump status for pumping stations and treatment plants.
Process monitoring
Pressure, temperature and level from existing transmitters, with alarms on limits.
Machine health
Run-hours, trips and temperature for early fault alerts and maintenance planning.
