Hi all, I have a fibaro 2 dimmer that used to be part of an installation that ran on Indigo domotics. It could be dimmed back then. I had a script that would set the maximim intensity to 15 at night, and 90 during day time. Otherwise standard. After excluding it and including it in Homey, I see that it does **dim during calibration** , but **not during normal operation**. If I set the dimmer slider to anything \>0%, if jumps to 100%. I have removed and re-included the device multiple times, tried a dimmer 1 app, and even tried the qubino app (just in case, because the unit is built in and quite hard to get to). Does anyone have an idea hoe to fix this? Thanks! Mark ---

Did you check the advanced settings? You can enable/disable the dimming functionality there. ---

Hi, yes I did. Dimming has not been turned off 🙂 ---

I found out the hard way that the minimum and maximum dimming range values that Homey displays after inclusion do not match what is actually set in the device. try changing the min and max manually to see if the inclusion process has set them at a weird value. ---

Hi Edwin, I tried that too. It is very strange. Is there a way to factory reset the hardware _through homey_? ---

I have the exact same issue. After a calibration it’s not dimmable. Excluded the dimmer from homey. Did a factory reset. After the factory reset it seems to dim till about 50%. But after including it within Homey it’s not dimmable anymore. It’s flipping only between on and off Update 23-12 It seems that if I calibrate, the dimmer recognize the light as dimmable. After adding the dimmer within the zwave network it recalibrate itself again and then it is set back as a non dimmable light. Even setting the raw value 33 on 0 doesn’t seem to help. It is a led lamp with bypass. But it’s still too less Watt I think. As a workaround I did the following Recalibrate with another lamp. Change the lamp back and adjusted the min and max brightness levels. That will do it
