Smart dimmers under existing wall switches (UK hub, German home)

Hi,

I have a couple of newbie questions. I have a few of wall switches that I want to keep and make smart. In one room I have 3 x 9 W LED bulbs connected to one wall switch (bistable). My understanding is that it is possible to control and dim the lights from my SmartThings and the wall switch itself independently, regardless of the actual state (correct me if I’m wroing). Will I need a bypass since my load is quite small?



Can’t seem to find these in the “works with SmartThings” list, do they work?

In another room I have two wall switches that control the same ceiling lamp. This means that either of the buttons will change the state of the lamp. Is there something similar which will work with that kind of setup?

Greatly appreciate the help.
