Ewattch: Wireless submetering, building controls and technical monitoring

Ewattch develops electrical submetering sensors, building-control hardware and EwattchCloud software for energy, comfort and technical monitoring.

Best for: Commercial-building retrofits combining electrical submetering with existing technical systems.
Less suited to: Assuming every LoRa device has the same electrical measurements or payload format.
Deployment: Sensors and actuators, optional SynapseCore control and EwattchCloud services.
Data in: Electrical readings, environmental conditions and technical building-system data.
Pricing: Pricing was not established from the reviewed technical sources; request a quote for the exact configuration.

Overview

Ewattch supplies field devices and software for building energy and technical monitoring. Its current architecture combines sensors and actuators, the SynapseCore controller and EwattchCloud. The company calls this its Hybrid Building System, reflecting the combination of wireless sensing with existing wired building equipment.

The platform description covers both energy analysis and operational information such as maintenance alerts and environmental conditions. This makes the system broader than a meter-reading dashboard. A project can begin with consumption visibility and add more detailed monitoring or control, with the controller and software handling different responsibilities from the individual sensor installed at a circuit or in a room.

Offering

The SQUID range provides 12-channel electrical submetering for single-phase or three-phase installations. The current catalogue distinguishes SQUID, SQUID Pro and SQUID Pro Rogowski. The Rogowski variant addresses higher-current applications; the published range should therefore be read by exact model and sensor option rather than assigning one current limit to every SQUID.

The wider technology portfolio includes SynapseCore for collection, logic and equipment orchestration. EwattchCloud presents the resulting technical and energy information across sites. These are complementary layers: a current-measurement device supplies readings, the controller connects and operates technical equipment, and the platform provides portfolio views, reporting and alerts to the people managing the buildings.

Technology

Ewattch publishes LoRaWAN payload-decoding resources and configuration downloads alongside the hardware range. These resources are important for an integrator using a supported device outside a ready-made dashboard: receiving a radio packet and correctly interpreting its measurement fields are separate steps.

The SynapseCore architecture identifies BACnet, Modbus, MQTT and LoRaWAN connections at the controller layer. EwattchCloud separately describes MQTT and APIs for third-party systems, including business intelligence and hotel-management applications. Those interfaces belong to their documented layers. They do not mean that an individual SQUID sensor directly implements every protocol available to the wider building system.

Markets

Ewattch's current homepage gives particular attention to hotels, property portfolios and technical-maintenance providers. Hotel applications combine energy submetering with room conditions and occupancy-related operation of heating, cooling and ventilation. The underlying objective is to connect operating information that would otherwise remain spread across separate technical systems.

The cloud platform supports multi-site comparisons and views extending from a property portfolio down to an individual measurement point. It also provides reporting and alerts for maintenance teams. This is useful for operators responsible for several buildings, where identifying a site with unusual consumption is only the start: the next task is to locate the responsible equipment or operating pattern.

Company

Ewattch's official company profile, linked from its own website, gives 2012 as the founding year. The legal notice identifies the French company and its headquarters at 13 rue Maurice Jeandon in Saint-Dié-des-Vosges. It names Nicolas Babel as publication director and supplies the company's registration identifiers.

The current technology presentation brings its hardware and software together around building operations, while the documentation site retains configuration and firmware resources for field products. This gives the business two visible aspects: development of connected measurement devices and an integrated building-management offering. Its public material describes French development of both products and platform, alongside work with installation and maintenance partners.
