The product with the item number 20757353 is the successor, has an improved battery and better technology.

I have both versions in the house. The P1 is more advanced, as Chantal says. With the P1, I would like to mention separately that it can reduce the movement interval down to 1 second. This is especially useful in a room where you stay for a longer time, for example, we have an Aqara P1 in the laundry room and it turns on the light quickly and leaves it on as long as you are in the room.
