Thinking of pairing these two together, because I’d like to use some dumb dimmer switches that look the part (that you cannot get in smart form). Thinking of a zigbee smart dimmer module by Sonoff.
Would the dimming controls interfere with each other?
What is this look?
Remember to tell us what part of the world you are in.
But there are a few dimmer modules in European market that you can integrate.
Combining a dimmer with a dimmer seems very hard in my opinion
There are quite a few zigbee dimmer pucks you can install behind the push button switch of your choice. Or were you talking about a rotary dimmer control?
You may be able to find a dimmer for which you can replace the face plate and knob with those of your choice.
EDIT: and be very wary of “no neutral” dimmers. They may be easier to install but they will also be far more likely to flicker. The Schnider pucks (micro modules) are terrible for this. Even with their load correction device and their own downlights. The Schnider dimmer mechanisms that do use a neutral do not suffer this issue.
I have the Samotech dimmers installed throughout my entire house (20 in total). They are actually quite small and can be used as single, double, triple, or quad gang depending on the faceplate configuration you purchase. You can choose between four different color knobs and two different colors of faceplates. I am very impressed with them and have never had any issues. I run them through zigbee2mqtt and they function flawlessly. I highly recommend them.
