Our sensors clip straight onto every circuit breaker and measure its current AND its temperature. No shutdown, no rewiring, half a day to install. The PanelWatch platform does the rest.
Designed and made in France · Var, Provence
An electrical panel often has dozens of circuits… and just one meter. Here is how we make every breaker readable, without stopping the site.
PanelWatch combines clip-on sensors, a controller inside the panel and a platform that turns measurements into decisions.
It clips onto the existing breaker and measures the circuit's current and temperature. No shutdown, no rewiring, no extra space needed in the panel.
Refrigeration, cooking, ventilation, air conditioning: PanelWatch groups every circuit by end-use and shows where the energy goes, hour by hour, day by day.
Equipment left on out of hours, overconsumption, a breaker running hot: you get an e-mail alert. Automatic weekly reports, in HTML and PDF.
| DIN-rail meters | Stick'n Sense | |
|---|---|---|
| Power cut needed to install | Yes | No |
| Panel rewiring | Yes | No |
| Space needed in the panel | One module per circuit | None |
| Temperature of every breaker | No | Yes |
| Circuits monitored | A few main feeders | All of them, up to 280 per controller |
We work with energy-efficiency consultancies and integrators, who deploy PanelWatch at their clients' sites. Three levels of detail, for three roles.
| L1 | L2 | L3 | |

| A | 46.8 | 36.6 | 42.8 |
| kW | 11.0 | 8.6 | 10.1 |

No need to force yet another dashboard on your teams. PanelWatch connects to our partners' information systems: every circuit's measurements feed straight into the tools they already use.
10-minute data, per circuit and per end-use.

In institutional catering, commercial restaurants and service stations: wherever operations can't be stopped.
Caisse des Écoles, Paris 17th arrondissement: 108 sensors. GIP RCCM, Saint-Lô: 84 sensors, installed by the site's own staff. Deployed with our partner Lite.
Alerts as soon as the fryer and grill operating schedule isn't followed: equipment no longer runs idle.
Also in operation: over 15 service stations · 6 GWh measured over 12 months.
Stick'n Sense grew out of a simple observation: to save energy, you first have to measure it, circuit by circuit. And to measure it everywhere, you need sensors that install without stopping the site.
We design and manufacture our sensors in France, and develop the PanelWatch platform in-house.
No. The sensors clip onto the existing breakers without touching the wiring. The site keeps running throughout the installation, which takes about half a day for a central kitchen.
In quick-service restaurants, the equipped Burger King outlets paid back the installation in under 8 months: about 30 MWh saved over the first 8 months, or €9–10k (excl. VAT) of savings per restaurant per year. For a central kitchen, the hardware costs around €7,000 (excl. VAT), for savings of 10 to 37% on the optimised end-uses.
A breaker or connection running hot is often the first sign of a loose terminal or an overloaded circuit. Monitoring temperature continuously lets you act before a failure, instead of finding out once a year during the thermal imaging survey.
Conventional submetering requires a power cut, rewiring and space in the panel, so it is limited to a few feeders. PanelWatch monitors every breaker, current and temperature, with no shutdown and no extra space.
Up to 280 breakers per controller, far more than a typical panel contains.
Our partners, or the site's own staff: the tablet installation tool guides the work and shows connected sensors in real time. In Saint-Lô, all 84 sensors were installed by the kitchen team.
In the PanelWatch platform, through automatic reports sent by e-mail (HTML and PDF), or straight into your own information system through our API.
In Europe, on servers run by our own team. Measurements never go through US clouds, so they are not subject to the US CLOUD Act. Access to the PanelWatch portal is restricted to authorised users, and data is exchanged over secure connections.
