Zone Not Following the Same Temperature or Schedule

Thermostats in a zone should share the same setpoint and the same schedule. If one device drifts, check whether the change was made on the zone or on a single thermostat.

Change the zone, not one tile

• Adjust temperature, schedule, or a hold from the zone so every included thermostat updates.

• A change on one thermostat tile can look like the zone “broke” when only that device moved.

Holds, shortcuts, and geofencing

• A hold on one device can temporarily split it from the rest of the zone.

• Home / Away / Vacation shortcuts apply the shortcut settings. If those differ from the zone schedule, the zone looks out of sync until the shortcut or hold ends.

• Geofencing can trigger Away or Home for the Home, which then changes the zone with everyone else.

• Smart Early-On on supported baseboards can start one room earlier than another if the rooms heat at different speeds — the clock time of the schedule event can look “ignored.”

Offline devices

If one thermostat is offline, it will not receive the zone change until it reconnects. Fix Wi-Fi first, then set the zone temperature again.

After recreating a zone

A new zone starts from the devices you selected. Re-apply the schedule if it did not carry over from the deleted zone. If they should no longer match, delete the zone so each thermostat is independent.
