When a 20/40/60 Control Switch is paired with an Air Quality Insert, or with one of the Temperature, Humidity and Motion variants, it turns on by itself under certain conditions:

• Air quality: turns ON when indoor air quality drops to moderate, and OFF once it has been good for 5 minutes
• Humidity: turns ON when relative humidity rises 15% above the daily average, and OFF once it has been back below that level for 5 minutes
• Motion: turns ON when occupancy is sensed, and OFF once the space has been unoccupied for 5 minutes

These rules run on the Insert itself

They work with no Wi-Fi connection and without the Swidget app, so the switch does its job on its own.

They run only while the Insert is not paired to the app. Once you pair it, the built-in rules stop, and the switch follows the Modes of Operation or automations you set up in the app instead.

If the rules are not running

The usual cause is Insert firmware that needs updating. Pair the Insert using the Swidget app on an internet-connected Wi-Fi network, then update its firmware, following Swidget App - Updating my firmware. Pairing stops the built-in rules, so once the update is done, factory reset the Insert following Completing a factory reset on an Insert. The reset removes it from the app, and the built-in rules start again. Do this for each Insert that is not behaving.
