Building energy monitoring hardware, from meter input to cloud.
Energy metering hardware for existing buildings, designed and built end to end: current clamps and pulse inputs on a custom board, firmware, a radio link and the cloud side that turns readings into history. For the radio, firmware and cloud, we start from our battery-powered LoRaWAN node, in field trial as one unit.

The problem
Landlords and energy assessors meet MEES and EPCs in the UK and the EPBD in the EU, and an EPC is a snapshot of a building at one moment. Continuous metering shows how a building behaves between those moments. The difficulty is fitting it to buildings that already exist: switchgear that cannot be shut down, cables that cannot be moved and meters that were never meant to report. Metering also has to be accurate enough to trust, and we would state accuracy from measurements on the finished board rather than assume it. Any work on a live electrical supply would be scoped with you at the start, including who is qualified to carry it out. Retrofit also means the board has to fit the space inside existing cabinets.
What we'd build
Clamp-on and pulse metering with firmware, radio and cloud
Metering hardware designed to be fitted to existing installations, with the wireless link and a history store behind it. It is design work for your project, not a meter you can buy from us today. Measurement accuracy, electrical isolation and safe fitting would be the first design questions, and we would answer them before any layout begins. Each channel would be labelled by circuit so that readings can be traced back to the cabinet.
| Layer | What we'd do | Detail |
|---|---|---|
| Metering board | A custom board for current clamps and pulse inputs, so that circuits can be measured without rewiring them. Mains or battery power would be chosen to suit the site. | Clamp ratings, the number of channels per board, mains or battery supply and how the board is isolated from the circuit it measures |
| Firmware | Sample, aggregate and report on a schedule you set, so that the radio is not sending every raw sample. | Sampling rate, what is summarised on the device and how a meter that has been reset or unplugged shows up |
| Radio | LoRaWAN, NB-IoT or BLE, picked to suit the building, with gateway placement planned alongside. | |
| Cloud | A network server and telemetry database keeping circuit-level history, with reports for your own clients. | On our node: network server and telemetry database on one self-hosted server |
| Mechanical | Enclosures and clamp fitting for existing switchgear, scoped with you at the start. | Fitting clamps around existing cables, enclosure size inside switchgear, and labelling |
How working with us goes
- 01 Scope We agree what has to be built, where it lives and where the data goes.
- 02 Prototype Working hardware and firmware on your bench, tested against real conditions.
- 03 Pilot A small batch on real sites, with fixes folded back into the design.
- 04 Production Design for manufacture, a production run, and support once it is in the field.
