Thermostat humidity reading is inaccurate or stuck at a fixed value.

Safety first: Turn off HVAC power at the breaker before removing the thermostat display.

• Clean sensor vents: Remove the display and gently clean any dust from the small vents with a dry, soft brush or compressed air. Do not use liquids.
• Compare with hygrometer: Use a separate hygrometer to compare humidity readings. If the Wyze reading is off by a consistent amount, note the offset.
• Reboot and update firmware: Reattach the display, restore power, and check for firmware updates in the Wyze app.
• Replace thermostat if sensor failed: If the humidity reading remains stuck or wildly inaccurate, the internal sensor is likely failed and the thermostat display should be replaced.
