The following is in regards to the Eria, the button, battery powered , Zigbee device, from Amazon:
These cost a bit less than the Hue Dimmer and can be used for a similar purpose if you're willing to TouchLink them. I prefer to use them with my Zigbee hub, Hubitat, for a variety of more powerful purposes. (Hubitat supports these devices natively; if you're using a different Zigbee HA hub like SmartThings, don't expect it to work unless they have a driver/device handler for it or if it's on their whitelist; it should work with Zigbee LL as described above).
Unlike the Hue Dimmer, these fit in a standard decorator plate, which besides the price is their main advantage (if you only want to use them on Hue, the app doesn't "see" them so you won't be able to, for example, cycle between scenes with multiple presses, unless there's a way to set that up that I don't know about, so the Hue Dimmer may be more functional if you value that). They are arguably a bit better-looking, too. Both only come in white, and both also come with their own mounting plate (for on-the-wall or anywhere installation), but again, the Eria can be mounted in any decorator plate (they even include wire nuts if you want to replace an existing switch with it).
My only issue is that it takes a second or two after holding the "up" or "down" buttons for it to send a "held" event (release any quicker and you'll just get a "pushed" event). Some of this could be specific to my hub, Hubitat, but I imagine it's only interpreting what the device itself sends. In any case this means that if you want to configure it to start dimming when the button is held and stop dimming when it's released (emulating what you'd expect), you'll have to hold it down for a while before it will even start. This can mostly be worked around by using "pushed" to just step the brightness up/down by a specific level, but I still wish the "held" delay was a bit less.
4.0 out of 5 stars Integrates well with the Hubitat system

I now have a total of three of these remotes controlling two dimmers. One is stand-alone. The other has one directly controlling and the second configured to do a virtual button push on the one directly controlling the dimmer. These work very well I am very happy to have discovered these.
Why only four stars? First off, the cover is hard to remove and even harder to put back on after putting the holder on the wall. I was sure something was going to break as hard as I had to hit it to get it to snap back in place. It did survive. It shouldn't be that hard to work with. Second is that it appears to only come in a stark white color. The switch plates in our house are all almond color so the cover stands out. An option to have different colors would be nice.
If you don't mind the white color only, then this is a good remote to get to operate a dimmer. The cost is reasonable and it functions properly.
