Sowee

What Sowee does

Sowee by EDF is a France-based, wholly-owned subsidiary of EDF (Électricité de France) that sells connected home energy-management products and services to French residential customers. Founded in 2017 and headquartered in Courbevoie, the company employs 51–100 people and operates as EDF's consumer-facing digital brand for energy efficiency and demand-side management.

Its flagship offering is the Station Sowee, a connected thermostat hub in two variants: Station Élec' (for electric radiators, from €6.90/month) and Station Gaz (for gas boilers, from €9.90/month). The hub communicates with installed Récepteurs (radiator receivers), a boiler Actionneur, and optional connected thermostatic heads (from €1.50/month add-on), using dynamic thermal models to schedule heating room-by-room, detect absence, monitor CO2/humidity, and track consumption. Sowee's stated savings claim is up to 15% on energy bills for electric heating and up to 20% for gas heating, against a 20°C constant-setpoint baseline. The platform also supports an Effacement (load-shifting) option that lowers heating during French grid peaks in exchange for a €3/month rental discount.

Sowee monetizes through monthly hardware-as-a-service subscriptions with professional installation included (or €85–€90 standalone), accessories and connected-device sales (DiO, Philips Hue, smoke detectors), bundled Sowee-branded EDF electricity and gas supply contracts, and the Smart Charge EV charging service co-developed with Volkswagen (savings wallet at 1.9 c€/kWh, ~€170/year user benefit). Distribution is fully DTC — website, iOS/Android apps, and a phone-based inside-sales team — with no third-party resellers; physical installation is handled by a nationwide partner-installer network. Marketing emphasizes content (48+ blog articles), SEO, Instagram, and EDF brand association. Integrations with Delta Dore, Philips Hue, Muller Intuitiv, Saunier Duval, Daikin, and major connected radiator brands extend the Station into a broader Logement Connecté smart-home ecosystem.

Broad incumbents

• Honeywell Home (Resideo): Incumbent heating-controls manufacturer (T6, T10 smart thermostats) with global distribution and deep installer relationships. Competes broadly with Sowee on connected heating hardware and professional-install models in the European market.
• Schneider Electric (Wiser): Global energy-management giant whose Wiser connected-thermostat and home-energy suite competes in residential HVAC control. Comparable as a broad incumbent applying industrial energy-controls R&D to the residential smart-thermostat layer.
• Google Nest: Consumer smart-home platform whose Nest Learning Thermostat is a category-defining competitor to Sowee's Station. Overlaps on energy-savings claims, remote control, and home-assistant integrations.
• Somfy: French specialist in motorized shutters, blinds, and smart-home control (TaHoma hub). Overlaps with Sowee's Logement Connecté ecosystem ambitions (lighting, shutters, scenes) on home-automation use cases, though Somfy is not primarily a heating-control vendor.

Direct peers

• Tado°: Munich-based smart-thermostat vendor offering HVAC, boiler, and AC control subscriptions across Europe including France. Directly comparable subscription model (€monthly tier) and Effacement-like smart-scheduling features, competing for the same home-owner customer.
• Delta Dore: French smart-home manufacturer and Sowee's integration partner; also sells its own Tydom thermostat/connected-heating ecosystem. Comparable because Delta Dore addresses the same residential HVAC-control category with proprietary hardware and comparable smart-home integrations.
• ecobee: Toronto-based smart-thermostat vendor (now owned by Generac). Comparable subscription-free hardware + cloud-services model with smart-scheduling and integration with HVAC OEMs — direct competitor on product features and target buyer.
• Qivivo (Engie): French smart-thermostat brand wholly-owned by Engie (EDF's principal utility competitor). Offers competing connected heating control integrated with Engie energy supply contracts — the closest analog to Sowee-by-EDF's utility-bundled positioning.
• Netatmo (Legrand): Paris-based smart-thermostat and connected-home manufacturer, owned by Legrand. Competes head-to-head with Sowee in the French residential heating-control market with similar connected-thermostat hardware and Apple HomeKit / Matter integrations.

Regional players

• Atlantic: French HVAC and heating-equipment manufacturer (radiators, heat pumps, boilers). Comparable as a French residential heating player whose connected-heating OEM partnerships (Cozytouch) intersect with Sowee's heating-controls category, although Atlantic focuses on equipment rather than controls software.
