Generac Holdings, a company best known for its home and commercial backup generators, quietly acquired Ecobee in 2021. The smart thermostat maker, valued at around $100 million at the time of the deal, joined a portfolio that extends well beyond power generation.

What You Need to Know

Ecobee is a privately held Canadian company founded in 2007 that makes smart thermostats and sensors. Generac bought Ecobee to strengthen its position in home energy management, not just standby power. The acquisition gave Generac access to Ecobee's connected thermostat user base and software platform.

Generac's Energy Management Bet

Generac has been working to transform itself from a generator manufacturer into a broader energy technology company. Buying Ecobee fit that strategy. Smart thermostats can communicate with a home's electrical system and, when paired with a battery or generator, help manage energy loads during peak demand or outages.

The acquisition also gave Generac a direct relationship with homeowners through Ecobee's software. That connection allows the company to offer services like demand response programs, where utilities pay customers to reduce power usage at peak times. Ecobee's thermostat acts as the control point for those programs.

  • Ecobee's product line: Includes smart thermostats, temperature and occupancy sensors, and the SmartCamera.
  • Generac's home ecosystem: Now spans generators, battery storage, transfer switches, and energy monitoring.

What Happens to Ecobee Users

For existing Ecobee owners, the day-to-day experience has not changed significantly under Generac's ownership. The Ecobee brand continues to operate largely independently. Smart thermostat updates, app features and customer support remain intact.

Generac, however, has begun deeper integration. The company now markets its generators and batteries alongside Ecobee thermostats. The goal is a unified home energy system where a power outage triggers the generator and the thermostat automatically adjusts to conserve fuel. Users see few restrictions on what equipment they can pair with their existing Ecobee devices.

Why This Matters

The Ecobee acquisition shows how the smart home market is shifting from individual gadgets to integrated energy systems. A thermostat is no longer just a thermostat. It becomes a sensor and controller for a home's entire power profile. For homeowners, this means smart devices will increasingly coordinate with major appliances and backup power sources. The practical effect could be lower electric bills through off-peak scheduling or longer backup power during storms.

For the broader industry, the deal signals that companies with hardware roots are building software platforms to retain customers. Generac is using Ecobee's technology to compete against other energy management systems from Tesla, Schneider Electric and smaller startups. The winner in this space will be the company that makes energy management feel invisible to the homeowner.
