I have an IRIS home automation system. I want to put my fan on an IRIS switch however the on/off switches require a neutral - the dimmers do not. The neutral in the box is nearly impossible to get to... so my thoughts were to just use a dimmer but only run it at 100%. I understand its not a good idea to change the speed of a fan using a dimmer. Considering I have no desire to change the speed with the dimmer and plan on running it at 100%... is this safe?

This is the dimmer

In the most ghetto since yes. But I wouldn't count on fan lasting as long. –  DMoore Mar 4 at 20:53

Most likely this switch sends a low level voltage through the switched device even when the power is off (which is confirmed by reviews of LED's flickering when the switch is off). I don't have enough knowledge to say that would be bad for a fan, but running a switch with a dedicated neutral for the smart components would be the better option IMO. –  BMitch Mar 4 at 21:43

Speaking from experience with the X10 equivalent, no. Even with the switch at 100%, the switch will overheat. You need a switch with a relay. Do it right or not at all; it's not worth burning your house down over.

OK so lets say I use a switch instead... can I just tie the neutral on the switch to the ground wire? I think its just there to help with the zwave. –  user20257 Mar 5 at 17:41
    
No. While it might work, it is not safe. –  longneck Mar 5 at 17:43
    
longneck is right. My comment was written before you showed what type of dimmer it was. My comment was for the old-standard dumb dimmers. Which I did have hooked up to a fan and said fan's motor went out after 8 months. –  DMoore Mar 5 at 22:44
