Does anyone know of a mechanically quiet "appliance" module?   I wish to turn off the power to an appliance that is powered by a plug-in power supply.

The problem is the module will be in the bedroom and the appliance module I have (Leviton) makes a "click" on each actuation.  While it is not terribly loud, it will likely wake one of us up if actuated during the night.

Thanks

Use the ON/Off function in a Z-wave dimmer.

Living in the Land of Oz, give me a vegemite sandwich. Home Seer, Vera Lite & Edge, Popp, Black Cat Smart Hub & Vera G, Black Cat Lite 1 & 2's a Black Cat Dimmer or 2, Fantem Tec and then some  Black Cat Cat's Eye PIR's & Door-Window Sensors, RFXComm, Broadlink RMPro & Mini plus a Z-UNO or 2.

Thanks zedrally, however all the dimmers I have ramp on and ramp off.  Usually not good for a switching regulator (the wall wart).

Then look for a Z-Wave switch that uses a SSR (solid state relay).


Just out of interest what sort of equipment are you trying to control?

Must not be a light or anything that makes noise as that you also wake you up.

All the switches I know have a standard relay in them and make a relay click when turned on in a very quiet house. Atleast mine do.

At the risk of getting hammered, if the use of a dimmer is not possible then I would build my own using a Z-UNO and a SSR.


Straightforward enough.

google: yourvoltage Solid State Relay


Fairly straightforward to adapt the 4 channel example to just 1 channel substituting the Relay for a SSR.

Cooper makes a plug in dimmer that lets you configure the ramp time to zero, as well as always set the turn on default to 100% via programmable parameters

Model is RFLDM

The reason that you hear that click is because appliance modules are rated to carry the higher current draw of the typical appliance, think  toaster or coffee pot.  If all you're looking to control is a wall wart than an appliance module is overkill.  There are light control modules out there that are just simple on/off and do not dim at all.  That's what you want....!

Depending on the application, you could also try one of the Aeon Labs DSC26103 Aeotec Z-Wave Micro Switch modules. Don't know how quiet it is though.
VeraPlus, Ecobee, Legrand Adorne and too many Z-Wave devices to name

I know this is an old thread but doesn't appear to have been answered without building a custom SSR module

I am looking for some quiet plugin z-wave modules to switch some LED lamps - my main concern is, I want it to be quiet as possible and not a loud click of a relay. Using a lamp module doesn't seem to be an option as the required minimum load just isn't there with LED bulbs.

My last/current experience with plug in modules is X10 appliance modules - these make a loud clonk and not very graceful. 

I am guessing some are quieter than others?

What about a z-wave outlet?  Might be a little quieter since it is recessed in the j-box.
