This feature is not supported on the KE100. But you can consider getting a new Kasa KE110, a room thermostat that can control multiple KE100s simultaneously, and it can also monitor room temperature and humidity.

The smart control rules configured on the KE110 will apply to all connected KE100 units. Additionally, with the Hold Duration feature, you can decide how smart control resumes after a manual temperature adjustment: it can continue until the next scheduled time block begins, until a preset duration ends, or only resume when you manually re-enable it.
