Running residential demand response programs at scale is hard

Thousands of homes and devices, dozens of device makers, marketplaces and DERMS platforms, plus incentives, messages, data and load shed. Mysa Harmoni puts it in order.

  • One maker for every home

    Mysa thermostats for baseboard, in-floor, mini-split and central HVAC, with water heaters next.

  • One place to run events

    Dispatch from Mysa Harmoni or the DERMS you already use, and see load shed live.

A Mysa for baseboard,
in-floor, mini-split
and central HVAC

Whatever heats or cools a home, there’s a Mysa for it. More of your customers can join, and your program has load to call on in winter and summer.

Utility-grade security:
SOC 2 Type II and
in-country data,
as standard

Included in every Mysa Harmoni program, with nothing to add on or pay extra for.

    Independently audited security controls. Device data comes straight to Mysa, with no third-party cloud.

  • Data residency by country

    Your program's data stays in your country, set for each utility.

  • High-availability cloud

    Redundant hosting with failover, and devices that reconnect on their own over Wi-Fi.

  • Privacy law

Keep your DERMS, your implementer and your process. Mysa brings the thermostats, the enrollment and the homeowner app, so your customers get more from every program.

  • Utility program managers

    DSM, DR and EE teams judged on cost-effectiveness, enrolled kW and EM&V results.

    Your customers get a thermostat they choose to keep. You get enrolled kW and device-level results for EM&V.

    Plan your customer offer

    A ready-enrolled Mysa fleet in every thermal load type, delivered into your platform.

    More dispatchable load for your utility clients, without building device support or running enrollment yourself.

  • Program implementers

    Meet enrollment targets with less outreach, and add multi-residential buildings as a new segment.
