Totem didn't begin as an energy platform. It began with fixing the internet.
How a tool for rebooting routers became an intelligent, room-level energy-management system — now proven across a live 122-room building. And the team that built it.
Where it started
Years ago, we set out to build a smarter way to support internet service providers. At the time, nearly every common connectivity issue had the same fix: restart the router. But in practice it wasn't that simple — customers struggled with the basics of powering devices on and off, and support teams (and family and friends) became the default troubleshooters.
So we built Totem: a tool that could monitor a home's internet connection, detect when something was wrong, and remotely power-cycle the router — solving the problem instantly, without the frustration.
From routers to networks
Once it worked, we didn't stop. We expanded Totem to map entire networks — identifying devices, access points and connections across a home or building — and introduced satellite Totems: in-wall units that could control power to connected devices. Totem had become a distributed network-control system.
The pivot
At a trade show in Amsterdam, one question changed everything:
The answer sent us in a new direction. By integrating industry-grade energy measurement, Totem could become a platform for real-time energy monitoring and control. Totem evolved from managing internet connections to managing energy itself.
Building the platform
From there we rebuilt Totem for a more resilient future — a cellular fallback (NB-IoT) so control survives an internet outage, a cloud platform on Amazon Web Services for real-time monitoring and updates, and a wireless mesh network connecting hubs and in-wall units across an entire building. It wasn't easy: early versions wrestled with range, connectivity and data transmission. Through many hardware and software iterations, we made it robust.
Proving it at scale
Our first major deployment came with Unilife at Bargate House, Southampton — a multi-storey modular building, an environment notoriously difficult for wireless communication. It became the perfect proving ground. We adapted, optimised and learned.
Today 122 rooms are under Totem management there, with around 149 in-wall units across the building — the additional units placed through the corridors to strengthen the mesh.
Live, and publicly verifiable
Bargate House has been live since January 2026, and its savings update every week for anyone to see — not a one-off claim.
Totem today
What began as a way to reboot routers is now a platform for intelligent energy management — giving buildings the ability to see exactly how energy is used, control power at a granular level, and keep running reliably even when networks fail. And we're just getting started.
