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.

They have huge FW problems and they know it. For some reason they don't want to fix it unless you create a ticket. Even than it has problems. The stock FW has a memory leak and it locks up. The switch will fail in either positions and the manual switch will stop working. This is a huge fire hazard and breaks local code.
Do not buy their switches. Their switches has several issues and not worth any price. So sad, since it started so strong 6 years ago.

I find it using the old firmware is more stable! Dont update the firmware
The dimmer are great for changing brightness depending on time of time. You don't want the rooms too bright at night so i set them for 50% at 8pm every night and go back to 100% in the morning.
For the bathrooms, the motion sensor turns on the fan also as the kids would always forget to turn on the fan during bath. I actually set it to turn on everyday during their bath time.
There are so many uses for this stuff. The one bad thing about this is Kasa switches are not that reliable. I have swapped out 5 in 3 years. I was looking into swapping them all out for Leviton but they are 2.5x the price of Kasas.

So if you want to keep the light on you have to turn off the motion sensor setting in the app. There is not even a way to use the app or any of the smart integrations to make it stay on.

You might be able to program it to reset the motion sensor after 30 minutes of no activity and leave it at previous light setting. You can do alot more in TAPO app (you can use the Tapo app for Kasa switches also).

I actually got rid of all my multi-pole and only have 1 left. I found after putting in all the motion switches, there is no need for multi-pole.
For bathroom, i have the regular recess light and the mirror light. I also have the fan control. I use the motion sensor and dim for the lights so they come on whe you go in to the bathroom. The fan acts the same way as the light and also motion activated but is probably overkill as you can just program it to follow the light.
