ubisys: Zigbee switching, metering and heating controls

Overview

ubisys combines building-control hardware with its own Zigbee software and gateway products. The company overview describes a range extending from individual room controls to commercial building applications. For energy projects, the useful distinction is between devices that measure electrical consumption and devices that influence a heating or lighting load. Both can contribute to an energy-management system, but they supply different evidence.

A metered S1 switch can provide consumption information for its connected circuit. A heating regulator instead changes how heat is delivered. Comparing these products should therefore start with the required measurement and control point, rather than grouping every connected actuator under an energy-meter label.

Offering

The S1 installation leaflet describes a flush-mounted radio switch with integrated power-consumption measurement. It can retain ordinary wall-switch operation, and the documented factory configuration connects its switching input to its output before a radio network is configured. The leaflet also identifies a Zigbee 3.0 radio and the installation dimensions and electrical limits for that variant.

The climate range serves a different task. H1 is a battery-powered radiator thermostat with an integrated temperature sensor. H10 is intended for underfloor heating, with optional thermostat, sensor, demand-detection and pump-control interfaces. The physical heating system therefore determines which family is relevant before software features are compared.

Technology

The S1 technical reference is aimed at integrators and documents the device interface rather than only the consumer app. It is the appropriate starting point for checking endpoints, attributes and the commands a third-party implementation needs. A catalogue radio label alone cannot establish that a controller reads or writes all those features correctly.

The Matter explanation identifies Conflux bridging in the G1 gateway. That provides a route between Zigbee devices and Matter ecosystems; it does not turn every field device into a native Matter endpoint. ubisys also explains that controller feature support varies. Confirm which measurements and controls survive the bridge before choosing it as the project's data path.

Markets

The ubisys case-study collection names VIVAWEST, Hong Kong Telecom and Økern Portal among its building references. At Økern Portal, ubisys describes working with lighting specialist Glamox on a system with more than 7,500 lighting nodes and 250 G1 gateways. Sensors measure daylight, occupancy, temperature and humidity, supporting automated lighting and daylight simulation.

The automation software organises a building into zones and offers occupancy, hold-time and standby-lighting settings. Its Human Centric Lighting template adjusts lighting through the day. These examples show how the company's software and gateways extend beyond individual home switches into coordinated commercial lighting projects. Project quantities are manufacturer-reported.

Company

The official company page dates ubisys to 2005 and gives its address in Düsseldorf, Germany. It describes both own-brand products and customised or white-label work. This profile uses that stated business origin rather than substituting a later company-registration date found in third-party records.

For procurement, distinguish a standard ubisys product from a customised device based on the company's technology. The published technical reference binds its specifications to the named model, while the gateway discussion describes a separate integration layer. Keeping those responsibilities separate makes it easier to identify who supplies firmware, who maintains the controller integration and which documentation applies to the installed system.
