Frequently asked questions
Do wireless smart thermostats work without a C-wire?

Can I install a smart thermostat myself?
If you’re comfortable with basic wiring, many smart thermostats come with step-by-step guides and video tutorials. For high-voltage models like the Mysa, professional installation is recommended due to safety concerns.
