I have both Fibaro dimmer 2 and Aeotec nano dimmer. They seem to work just fine, however, when these are off and e.g. an automation sends a set brightness of 50%, they take several seconds to react. The lower the set brightness, the longer it seems to take.
Both of these have a parameter controlling the transition rate, which is set to the smallest value allowed, (1s, also don’t want 0s since the transition is nice to have). The transition is handled by the device and not the automation. Normally this is not a big issue, but I have two of these installed in a hallway and a bathroom, where you want them to react a lot faster. It basically turns on the light when I have already left the hallway.
Note: Both are installed in a 2wire configuration with the recommended bypasses.
