Help needed on dimmers

[pdekuewit]

Is it possible to read the value of a dimmer and set it as an variable into another dimmer ? So in fact copy the value of one dimmer into another ? The second dimmer follows the first.
If so is there an app I can use ?

The reason for this question is as follows, I have currently 4 Fibaro dimmers who work fine however they have problems with the high frequency put on the mains to switch devices. The dimmers (all of them) slowly increase the intensity of the lights without updating the controller. F.i when a dimmer is set on 40 and the frequency starts on the mains the light will increase to about 50 or 60, but it seems to report back still 40. The high frequency disturbances appear on regular hours. If I can start a time action short after these disturbances reading the value of the dimmer and putting it back into the dimmer, it should be reset to its original value. I tried it with a scene and putting back the old value and this works but the value was fixed an I want it variable.
I have mentioned the problem already a Fibaro, but I have the feeling that they will not respond quickly.
This could be a temporary work around.

Thanks in advance

You can use BindDevices for that. Or LogicalRules.

Thanks, but how do I get the current value of a dimmer as variable ? ( I am not familiar yet with the way these things work).
