I’m thinking about upgrading my relays and previously got recommendations for Qubino Mini but they don’t seem to be available anymore.
What smart relays do you use? Preferably those that can both be used with and without the dimmer function. For the Partner-approval-factor it should of course be usable without the smart functions as well.
There are some Zigbee dimming relays/modules which should work with your Zigbee stack of choice. I haven’t used them myself as I use Zigbee dimmer switches instead, but I’ve seen others recommend them. There’s a few different brands depending on your country.
I can also second the recommendation for the Shelly Dimmer 2. Works out of the box with the HA Shelly integration, and can also be flashed with ESPHome or Tasmota if you really want. It can also be used in detached mode to work with smart lights I believe too. My home is mostly Zigbee but I have a few Shelly devices and they have all been solid.
I believe detached mode refers to having the wired switch act independently from the light, so what you want is attached mode
