Harrison or Add-a-Motor Gordijnrail

[Nielsy]

I have now 1 Add-a-motor 1100-2 elec. rail but it's make a lot of noise and I wonder if there is somebody here with a harrison rial?

Maybe somebody here know more about harrison vs add-a-motor??

Because I want more elec. rail, and harrison is also with a homeseer plug-in and add-a-motor is IR instead of RF.

And want to know what the noise is of harrison?

I think you answered the question yourself. Harrison electrical curtainrail is easy to connect to a home automation (Domotica) system. I have like 5 rails myself and working great. about the noise, yes you hear them, but what is loud?
