Meet Mysa: The only Smart Thermostat that lets you take full control of your electric heat. Mysa is the first ever high-voltage thermostat that is truly smart. It is fully featured for the conscientious consumer: smart learning features which can save up to 26% on energy bills, remote access to control your home’s heating through their smartphone from anywhere in the world, and integration with popular smart home platforms (Amazon Alexa, Google Home, and Apple Homekit).

Your heat is in your hands.
  • Remote Control: Now App-roaching comfort - If you have access to your phone, you have access to your home. Don’t worry about leaving the heat on - control your heat from anywhere in the world with our Android and iOS apps.
  • Set a schedule in minutes: Mysa’s scheduling system gives you the flexibility to change on the go. Leave the 9 to 5 behind and decide your own program. You and your thermostat will have the same schedule - or no schedule at all.
  • Energy Charting: Daily tracking of your energy use will help you see how Mysa's saving you real dollars.
  • Vacation Mode: Jet-setting doesn’t mean resetting. It just means simply pressing a button. So whether it’s for a day, a week, or until you’ve got the perfect tan, you don’t have to worry about your heat kicking in back at home.
  • Zone in on comfort: Team up your Mysas to add precision to your home heating. Do bedtime right by keeping the kids’ rooms on the same schedule, or keep the whole basement nice and cozy for movie night.
  • Snazzy, Stylish, Smart: Simple never goes out of style: Mysa follows a straightforward design philosophy - less is more. No complicated menus, no ugly screens. No excess. Just Mysa smiling brightly back at you.
  • Installation: Your electric heaters just enrolled in school. Baseboard heaters got a new best friend, and fan-forced heaters got their new biggest fan. Mysa’s the smartest choice for all your high-voltage needs - from 120V all the way up to 240V.
