Need advice? More information?

Everspring In-wall On/Off Module is a Z-Wave module that allows you to toggle electrical appliances wirelessly. The device installs behind a wall switch and allows you to remotely control the appliances connected with the power outlet through a Z-Wave home automation gateway or remote control.

Control Lighting

The smart In-wall module has been designed to work perfectly with incandescent, fluorescent or LED lighting. Since it installs inside the wall, it's a convenient way to add smart wireless control to any lighting source in your home. At 230V voltage, this module can support up to 11A resistive, 1200W incandescent, 700W motor, or 320W (40W*8) fluorescent load.

Overload Protection

For security, the unit can detect overheating and will automatically turn off the relay to avoid damage. It's also smart enough to automatically remember the status of the relay when it's powered again.

Easy Installation

The In-Wall On/Off Module supports 2 sets of dry contacts that can be wired conveniently inside the wall to wirelessly control the connected device. The module does not disrupt the normal functioning of the device, and still allows you to control the connected electrical devices normally from the wall switches .

Note: This unit requires a 3-wire system (including neutral) - Please check your installation before purchasing. Further information about 2-wire and 3-wire installations is available in Application Note 23 - Understanding 2-wire and 3-wire Lighting Systems.

Z-Wave Plus

Z-Wave Everspring In-wall On/Off Module is Z-Wave Plus Certified. Z-Wave Plus (5th Generation Z-Wave) offers a lot of new features including increased range, extended battery life and Over The Air upgrading (OTA).
Take a look at our "What is Z-Wave Plus" guide for more information.

Excellent little device.
This in wall on/off relay is a great little device and is working very well so far. I am using them to control a number of appliances in the house, works well with samrtthings too (you do need to install a device handler as this appears to be one of the devices not yet approved by ST). I like this device because it is silent and the on-board LED is not permanently lit. The device is also advertised on this site with energy monitoring capabilities but I am not able to verify or prove that functionality.

So far so good
A great little unit at a fantastic price. Range seems really good, even on my pre-gen5 network and device responds well to all commands. Was very easy to include into Homeseer and works perfectly. Good sized unit that fitted in my 40mm patterns with no issue. Might fit in a smaller gap but I had a 3 switch face plate, so lots of cables. Please with it so far, and even just bought another!

Easy to wire and works well.

Does exactly what it says on the tin, no messing
Very small form factor, deep terminals for secure connection, great documentation and 10 min install and setup. Works perfectly with Vera. Instant switch on/off and very minimal delay reporting back when manually switched. Very happy.

Has anyone used this with smartthings?
Glenn S. 5 Mar 2017
Can this be wired with mains voltage to the S1 or can that only be the 3v? I was hoping to use it in a 2 way lighting circuit without altering the incoming mains switch voltage. I know you can do it with the Fibaro relay, as I have this on another 2 way circuit, but these Everspring units are cheaper. Thanks, Richie

Could I use this to switch a bathroom electric radiator rated at 1000W ?
David G. 30 Aug 2016
BEST ANSWER: It's rated at 11A for a resistive load like a heater, so that is more than enough. A current of 11A is roughly a load of 2500W, so plenty of capacity.
What size back box would you need for this module? Is it smaller than the Qubino / Fibaro dimmers that require a 45mm back box?
Neil R. 27 Jun 2016
BEST ANSWER: These are much bigger than the Fibaro / Qubino modules so a 45mm back box is still recommended.
