Ewattch

What Ewattch does

Ewattch is a privately held French société par actions simplifiée (S.A.S.) founded in 2012, headquartered in Saint-Dié-des-Vosges, that designs and manufactures an end-to-end IoT and software stack for smart-building energy and technical management. Its offering combines proprietary LoRaWAN/4G field sensors—the Squid sub-energy meters, Tyness industrial sensors and Ambiance indoor air-quality sensors—with the SynapseCore Hybrid Building Controller (HBC), an ARM Cortex Quad-Core device running secured Embedded Linux that fuses a wired industrial BMS (Modbus, BACnet, KNX, DALI, MQTT) with an embedded private LoRaWAN hub. These devices feed EwattchCloud, a 360° SaaS platform for multi-site hypervision, energy management, BMS fleet management and automated regulatory reporting (Décret BACS, Décret Tertiaire, ARS legionella). All hardware and software are designed and manufactured in France.

The company targets primarily hotels and hospitality groups (Accor, Best Western, Maison Albar Le Vendôme), with secondary segments in real-estate asset management (Groupe Centaurus), multi-technical maintenance and facility management (Steamo by Armonia), and industrial/tertiary buildings (KFC, Mobalpa, FSEF Santé Études). It goes to market through direct sales (free audit, quote within 48 hours), a certified partner programme with EwattchBuilder customisation tooling and Ewattch Academy training, three named French distributors (DataPrint in Paris, IP Systems in Lyon/Bron, SARL MAE on Réunion Island), and a self-serve free trial of EwattchCloud. Revenue is generated from hardware sales (quote-based, ex-works, 5-year commercial warranty), professional services (training, pre-configuration, integration support) and recurring SaaS subscriptions, with a focus on French regulatory compliance as the principal competitive differentiator.

Ewattch has launched or expanded multiple product lines in 2024–2025 (SynapseCore HBC, Squid Pro Rogowski LoRa, Tyness Performance, Ambiance sensor range, EwattchCloud 360°), broadened its partner ecosystem, and extended distribution to the overseas territory of Réunion Island, but discloses no external funding rounds, no revenue figures and no headcount trend. The legal entity (SIREN 750 606 246) carries share capital of €151,666 and the company operates with 11–50 employees under the direction of Nicolas Babel.

Revenue model

1. Hardware product sales (IoT sensors, controllers): Direct sale of Ewattch-designed Products (Squid, Tyness with add-on cards, Tynode, Toolbox, Ambiance range, SynapseCore HBC) and third-party Products/accessories. Pricing is differentiated by customer activity, buyer category and purchase volume, ex-works (EXW), packaging and transport not included, plus VAT. Customers retain title until full payment; transfer of risk occurs at contract formation. First order is paid cash; subsequent orders on 30-day terms by bank transfer or credit card, with mandatory deposit above €10,000.
2. Professional services (training, configuration, integration): Complementary services sold alongside hardware: training on product use, training on installation, pre-configuration of Products, and an Integration Support Service to assist partners/customers with deployment. Billed as a Financial Compensation per the signed Order, with rates on the Ewattch price lists.
3. EwattchCloud platform subscription and partner enablement: EwattchCloud 360° platform is offered as a SaaS-style cloud service providing multi-site hypervision, energy management, BMS fleet management, real-time maintenance and regulatory reporting. A free trial is available; partner certifications and access to EwattchBuilder for advanced customization are part of the partner program, supporting recurring revenue and partner-led sales.
4. Channel/distributor resale and partner enablement revenue: Indirect revenue via certified partners and distributors (e.g., DataPrint, IP Systems, SARL MAE in Réunion), who resell Ewattch products, deliver services locally, and receive training, certifications and access to EwattchBuilder in exchange for channel volume.

Core offering

Ewattch designs, manufactures and sells an end-to-end IoT stack for smart-building energy and technical management, anchored by the EwattchCloud 360° multi-site hypervision SaaS platform and the SynapseCore hybrid building controller (wired BMS + embedded LoRaWAN hub). Its portfolio is complemented by proprietary LoRaWAN/4G field devices — Squid sub-energy meters, Tyness Performance industrial sensors and Ambiance air-quality/comfort sensors — plus professional services (training, pre-configuration, integration support) delivered directly and through a certified partner and distributor network.

Product overview

Ewattch delivers a platform-plus-hardware IoT portfolio for smart-building energy and technical management. The architecture is anchored by EwattchCloud, a 360° multi-site hypervision and energy-management SaaS platform, paired with SynapseCore, a hybrid building controller that fuses wired BMS (Modbus, BACnet, KNX, DALI, MQTT) with a private embedded LoRaWAN hub. This core is complemented by a family of LoRaWAN field devices: the Squid range of non-intrusive sub-energy meters (Squid LoRa, Squid Pro LoRa, Squid Pro Rogowski LoRa), the Ambiance range of indoor air-quality and comfort sensors (Ambiance CO2, Ambiance, Ambiance Feedback, Ambiance Lite, Ambiance Lite CO2) and the Tyness Performance industrial multi-function sensor for predictive maintenance. Together, these products allow Ewattch to address hotels, tertiary buildings and multi-site portfolios with end-to-end energy monitoring, HVAC control, regulatory compliance (BACS, Tertiary Decree, ARS) and predictive maintenance.

Broad incumbents

• Schneider Electric: Global leader in building automation and energy management via EcoStruxure. Directly comparable as a BMS / energy management platform provider for hotels and tertiary buildings, but operates as a broad incumbent across the full building lifecycle rather than Ewattch's specialised hotel/tertiary IoT niche.
• Siemens Smart Infrastructure: Offers Desigo CC and a full BMS portfolio covering hospitality, real estate and industrial buildings. Competes with Ewattch on multi-site building management and energy optimisation, but at a vastly larger scale and with global installed bases.
• Honeywell Building Technologies: Major BMS and energy management player (Niagara, Forge, BMS platforms) serving hotels, offices and industrial customers worldwide. Comparable to Ewattch on hotel energy sub-metering and HVAC control, but as a broad incumbent with enterprise-grade offerings.
• Legrand: Global specialist in electrical and digital building infrastructure, with a growing BMS / IoT portfolio. Overlaps with Ewattch on hotel and tertiary building energy and comfort management but addresses a much broader electrical infrastructure footprint.
• ABB Building Solutions: Provides building automation, KNX-based control and energy management solutions to commercial real estate and hospitality customers. Comparable on multi-protocol building control and energy monitoring, but as a broad incumbent with a global footprint.

Direct peers

• Deepki: French SaaS platform for real estate energy and ESG data management. Direct peer on multi-site energy hypervision and Décret Tertiaire/BACS compliance reporting for real estate and hospitality portfolios, with a software-only (no proprietary sensors/controllers) model that contrasts with Ewattch's vertical stack.
• Smart Impulse: French provider of non-intrusive electrical sub-metering and energy analytics for buildings. Directly comparable to Ewattch's Squid sub-meters and EwattchCloud reporting, focused on the same French tertiary-building regulatory environment.
• Watteco: French designer and manufacturer of LoRaWAN IoT sensors and actuators for smart building and energy management. Directly comparable as a LoRaWAN-native building IoT hardware vendor and one of Ewattch's closest technical peers in the French market.
• NodOn: French smart-building IoT company offering wireless sensors, controllers and actuators (EnOcean, Zigbee, LoRaWAN). Comparable to Ewattch on the wireless retrofit and multi-protocol building automation angle, with overlapping end-markets in hospitality and tertiary buildings.

Emerging players

• Qucit: French software company applying AI to urban and building energy optimisation and predictive maintenance. Partially comparable to EwattchCloud on the analytics and optimisation layer, with a stronger software/AI focus and no proprietary field hardware.
