Building & Asset Management

Power metering, lighting control and remote asset sensing for smart buildings and infrastructure.

Embedded control and monitoring for buildings and distributed assets — multi-channel power and energy metering, DALI lighting-control interfaces, and low-power wireless sensors for equipment and infrastructure, integrated into BMS, energy dashboards and remote monitoring.

We design embedded control and monitoring for buildings and distributed assets — from multi-channel branch-circuit power and energy metering and lighting-control interfaces to low-power wireless sensors that watch equipment and infrastructure far from mains power or network coverage. Data integrates over standard protocols such as Modbus and Ethernet into building-management systems, energy dashboards and multi-site monitoring, turning buildings and field assets into measurable, manageable systems.

96-Way Branch Circuit Current Monitor

Designed for commercial and industrial switchboards, our Branch Circuit Current Monitor uses standard current transformers for non-invasive monitoring of up to 96 mains circuits at the same time. Data includes power (W and VA), energy consumption (Wh and VAh), power factor, and voltage and current harmonic content up to the 30th harmonic. Due to the modular design and centralisation of processing, the solution is extremely cost effective, less than £10 per monitored channel.

To make accurate power measurements, normally a voltage and current connection is required. Our monitor measures current using Current Transformers which clamp around the circuit to be measured. To simplify wiring, the Current Transformers plug in to remote measurement units which communicate over a network to the base station. The remote measurement units can each host up to 6 Current Transformers.

The innovative design measures the voltages, harmonic content and phases of the (up to) 3 mains phases at a central distribution point in the network. This can be a more convenient and safe location where a galvanic connection can be made, away from sensitive equipment or users. By using a smart network protocol, the exact timing of the current and voltage waveforms can be synchronised, allowing each current waveform to be paired to its phase voltage waveform to allow the calculations. The Current Transformers can be hot-plugged and the network is robust.

The metering quality exceeds the standard for domestic consumption meters so can be used for billing users of data centres or tenants in a building. Anti-tampering protection in each Current Transformer remote unit logs if a current transformer is ever unclipped from its wire or disconnected.

Current Transformers have variable characteristics, therefore the base station has a built-in calibration and characterisation loop, which can characterise each transformer before installation, and then the anti-tamper protection can ensure that the same transformer remains on the same circuit.

The metering can be read by the user interface or by various network protocols over the Ethernet connection. A simple TCP Modbus protocol (port 502) or HTTP (port 80) are available, and drivers are provided for integration with common building management systems (BMS) such as Tridium.

Work Site Theft Prevention

Utility companies have many temporary work-sites active at any time. The hazards to traffic caused by them are mitigated by traffic lights, road signs, lights, cones, and barriers.

However, this equipment is easily stolen, or moved by strong winds or collisions. If this happens, it could cause an accident leading to liability for the utility company.

The normal solution is to use patrols to monitor the work-sites.

The technical challenge was to make inexpensive devices that could be attached to all the equipment, which could detect if the equipment had been moved from its original location, and be able to report online. Since some work-sites are far from towns and may not have mobile telephone signal coverage, using GSM was not an option for reporting.

Additionally, battery life for each device has to be several weeks, even in very low temperatures. And the devices themselves must be completely robust to any environmental conditions, and not be expensive enough that they become targets of theft themselves.

Our solution used a combination of low-power mesh networking, attitude sensors to detect the change in position of equipment, and long-wave radio for over-the-horizon reporting of events.

Mould Detector

Our damp-and-mould monitoring system pairs low-power wireless environmental loggers with a cloud reporting platform, so social landlords, surveyors and letting agents can prove how they responded to a damp-and-mould complaint. Each kit records environmental conditions continuously for 14 days with no Wi-Fi or installation, then an automated Building Moisture Index and dew-point analysis distinguish structural or penetrating damp from condensation.

The output is a timestamped, disclosure-ready report aligned with Awaab's Law and the Housing Ombudsman's Spotlight recommendations, and the loggers are reusable across an unlimited number of properties.

How it works

Survey & requirements

We establish what must be metered, controlled or monitored across the building or asset estate, and the integration targets.

Metering & sensing design

We design the metering front-ends, control interfaces and low-power wireless sensors for the environment and accuracy required.

Integration & dashboards

We expose data over Modbus/Ethernet and integrate with BMS platforms, energy dashboards and remote monitoring.

Rollout & monitoring

We support multi-site deployment and keep the estate visible and maintainable over the long term.
