Question How do 2 way lights work with smart light switches?

In the non-smart world, I know you can have two mechanical switches that can control the same light. Also in the non-smart world, you can also have one of the switches changed to a dimmer switch that has the ability to click the dimmer on and off. Obviously, you wouldn't be able to control the dimming on the other side.

I'm looking at smart light switches that can allow a single light to be controlled by two switches. My question is, in this new smart world, can dimmer switches be used on both ends? What are good brands to use for smart dimmer switches?

I would highly recommend Shelly 2 Dimmer, which is a module that goes behind a standard light switch. They can be used with 2 way switching and also if you use a standard centre off retractive switch (think blind type switch) you can dim at the switch at both locations as well.
