High Energy Bills After Installing Mysa

Last updated: August 25, 2026

If the bill rose after installing Mysa for Baseboards, start with schedule and holds before assuming the thermostat is using extra power.

Schedule and Holds

  • Confirm each thermostat has a schedule and is not sitting on a high manual setpoint all day

  • Clear holds and tap Resume Schedule if a hold is keeping heat up

  • Lower setpoints when asleep or away. ENERGY STAR recommends about 7°C (12°F) cooler while away and 4°C (7°F) cooler while sleeping

Shortcuts, Geofencing, and Early On

  • Confirm the Away shortcut actually lowers temperature

  • If several people share the Home, geofencing can stay in Home mode until everyone has left

  • Early On (V2 and V1) can start heating earlier so the room is ready on time — that adds runtime

Device Settings

  • Heater Type should match the system (baseboard, fan-forced, or radiant)

  • Timezone should be correct so the schedule runs at the right hour

  • Min/Max setpoint limits in Device Settings stop accidental high setpoints

Other Causes

  • Mysa is often more accurate than an old dial, so the room may now actually reach the number on the display

  • More rooms with thermostats means more space being heated

  • Drafts, open windows, and a colder month will raise use even with the same schedule

On V2 and V1, open Energy to compare days after you change the schedule. Lite has no energy chart.
