Platform
End-to-end energy stack.
Product behaviour is controlled at the device instead of disparate firmware and cloud logic. The Edge speaks open standards, so everything above it is genuinely optional.
Talk to us See pricing →Four ways to fit our Edge, from a module integrated in the energy device to a standalone unit.
Edge
WattStack Edge is a low-cost, secure comms module with a tri-processor, hardware-enforced OEM sandbox, Wi-Fi 6, BLE 5.4, and Thread built in. OEM code runs in the sandbox with no route of its own to the network.
See the hardware →App
The WattStack App gives end users a modern control and telemetry experience, with the option of full white-labelling to match the energy device's brand and with smart automations built in.
See the App →Control Room
WattStack's Control Room provides one view of fleet operations and support tooling for manufacturers, housing associations, and installers covering all their WattStack devices across device categories.
See Control Room →API and Edge SDK
The integration layer. A documented, webhook-capable public API for telemetry, control and scheduling, and the Edge SDK for a manufacturer's devices to integrate at hardware level with WattStack.

Hardware foundations for reliable software.
Device aggregation services typically integrate cloud-to-cloud, reaching each device through the manufacturer's own platform. This scales quickly, but how a device behaves is implicitly inherited: features, firmware behaviour and performance vary by model, and the integrator has to design for whichever behaves worst.

Connect, map and firewall
The Edge connects to the energy device locally, using a mapping built with our Edge SDK that translates proprietary protocols in hardware into standard, grid-friendly protocols, firewalling the device in the process.
See the Edge SDK → -
Our cloud, or yours
The Edge links to the WattStack cloud, or to a third-party service, local or cloud, over the public API, giving the owner control and the operator oversight, and making it easy for the device to be optimised or earn from supporting the grid.
See the public API →
The only required element in the WattStack stack is the Edge which enables the hardware integration. Everything above it is optional and open, so a device can use our hardware alone or anything up to the whole stack, in any combination.
The patent pending secure boundary is designed to keep the bulk of the cyber-certification load on WattStack's side of it. The device team can focus on writing core device logic and inherit the boundary, which reduces the assurance work it takes on as UK requirements for energy smart appliances tighten.
You do not have to take system isolation on trust. It can be verified by reading the schematic or examining the PCB, and it behaves the same on every unit that leaves the line.
- Built for the direction UK regulation is taking, including PAS 1878 and the DESNZ / Elexon Smart Secure Electricity Systems programme
- One security model across every device on the platform
Interoperability
Open standards, end to end.
The WattStack Edge has the capability onboard to map energy device communications onto standard, grid-friendly protocols locally, without requiring mandatory proprietary layers.
