I had tons of problems with this model the most, ES20M. You check Reddit and you will find others with issues.
All the 100 switches were happier when they are on their own vlan. The vendor even told me to do that. I created a vlan just for one of the ES20M and it still locked up. Make sure your WiFi is only 2.4 for them.
Community Reviews
The Kasa ES20M motion sensor switch is best for hands free lighting and automation, especially in bathrooms, closets, hallways, laundry rooms, garages, and kitchens. It can trigger lights or fans on motion, then dim or shut them off on a timer, with useful schedules like lower brightness at night and full brightness in the morning. The convenience angle comes through clearly, and the price is often compared favorably with other motion or dimmer switches. The main concern is reliability, with repeated reports of lockups, fail closed behavior, and firmware problems that sometimes require a breaker reset or replacement.
The switch supports brightness scheduling so lights can ramp to different levels at set times.
The motion sensor can trigger lights on and then turn them off automatically using timers and schedules.
The minimum brightness behavior can help reduce glare during nighttime bathroom trips.
The automation setup can reduce manual switching by turning lights on and off based on presence.
The device can be configured for longer fan or accessory follow-up after motion detection.
Firmware can cause lockups and non-responsive behavior that may require manual restart or breaker resets.
Some failures can leave the switch stuck in a closed state, preventing manual power-off when lights remain on.
Reliability issues can be worse for early batches and some 3-way setups, with ES20M singled out for problems.
Connectivity and network compatibility can be fragile, including guidance to use 2.4 GHz Wi‑Fi and VLAN isolation.
Firmware update behavior can be confusing because the app may not show build numbers clearly, making it hard to verify patches.

The app auto updates to v1.1.6
One of the problems with the app, they don't show build number. So you don't know if they are patched or not. If I didn't happen to see the firmware push I wouldn't have a build number and would never knew the change. The auto update and push firmware have the same version number and look the same in the app.
