Thermostat randomly switches between heating and cooling modes without user input.

Safety first: No electrical work is required.

• Disable Auto mode: In the Wyze app, switch from Auto to manual Heat or Cool mode to prevent automatic changeover.
• Increase deadband: If Auto mode is needed, increase the temperature difference between heating and cooling setpoints to reduce frequent switching.
• Review integrations: Check any connected services (Alexa, Google, IFTTT) for routines that may be changing modes and adjust or disable them.
• Update firmware: Ensure the thermostat firmware is up to date to avoid known control logic issues.
