Thermostat does not follow programmed schedule; heating turns on/off at wrong times

Safety first: No electrical work required.

Steps to troubleshoot:

• Check the current time, date, and day of week on the thermostat and in the Tuya app; correct any discrepancies.
• Verify the time zone settings in your phone and Tuya account.
• Review the schedule in the app; ensure the correct days and periods are enabled and that manual override is not locked on.
• Disable and re-enable scheduling, then re-enter your desired times and temperatures.
• If the thermostat still misbehaves, update firmware via the app or perform a factory reset and reprogram the schedule.
