Physical Brightness Level Switch

[Sea]

I have a working Shelly Dimmer 2 inside a traditional toggle switch. I can turn it on/off with the toggle switch on the wall. I can control the brightness with the Shelly web UI, but not the wall switch.

What is a good way to add a physical brightness control switch to this setup? Preferably something cheap and uncomplicated.

I know this question has come up in one way or another earlier in this forum, but there is no clear answer.

Use a single push button and you‘re able to adapt the light intensity by long button presses. A bit more comfortable is a double button: With this gadget, you‘ll have a button for dimming up and another for dimming down.

Thanks @thgoebel ! Exactly what I was looking for.

For anyone else's reference, the wiring diagram with the double-button-no-neutral setup is:
