Essential Info

The Smartenit EZIO40 has four independently controlled relay outputs that operate normally opened or normally closed contacts. The four dry-contact relay outputs allow control of low voltage 120 Volt AC (up to .5 Amps) or 24 Volt DC loads. Each relay can be linked individually or with other the other relays on the device as a responder to a group command from an INSTEON controller. The device also has a built-in powerline interface and acts as a repeater of powerline INSTEON signals. Additionally, a programmable timer can be set on each relay to force an off condition providing momentary action from 1 sec to 255 minutes. The simple press of a button from your INSTEON KeypadLinc, RemoteLinc or from your cell phone through a SmartLinc, you can switch loads such as large relays, furnace heaters, blowers, chimes, momentary pushbuttons and more, the possibilities are endless.

While basic functions can be programmed manually, advanced functionality can be programmed with the EZSrve, central automation controller. If you already have a central automation controller or a software package for your INSTEON network that doesn't have the correct parameters to program the advanced functionality of this device, you can download the free Smartenit Utility Suite which works in conjunction with an INSTEON Powerlinc Modem (2412U, 2413U or 2413S). If you need PC-free operation for simple timers, the Smartenit Utility Suite also interfaces with the INSTEON Powerlinc Controller.

    INSTEON Compatible

  • The EZIO40 Controller is fully INSTEON compatible. INSTEON is a powerful home-control networking technology. INSTEON messages are transmitted throughout your home both wirelessly and through the home's existing wiring. All INSTEON messages are confirmed and repeated by INSTEON devices in the network, contributing to the outstanding reliability and performance of INSTEON products.

  • X-10 compatibility

  • The EZIO40 also works with legacy X10 products. If you have an existing X10 network, the Controller works with your X10 products and provides an upgrade path to an INSTEON network.

    As mentioned before... does not work with Insteon Hub!! I actually got it to connect but it would only switch one channel. Too bad, I was hoping to control my pool with this. Instructions were not clear and did not specifically say it would not support Insteon Hub.
    DICK -- richardson, TX   4/27/2014
    Does not work with the Insteon Hub. Only useful as a X10 controller
    STAN & MICHELLE -- rochester, NY   9/8/2013
    Works as specified. But one "hitch" with the X10 setup: One part of the documentation says to send the desired address and "on" command. However, it fails to mention that you need to do this THREE TIMES. I found this vital missing piece of information in another document... and then finally got the unit configured.
    DON -- cypress, CA   8/12/2013
    Nice product a little pricey per point but beats the micro module! Both this and the irrigation module have a heat issue and seem to run hot. Also the screws on the terminal are very small and difficult to use. and Will not tighten down properly. But for a quick 4 relay output it is great and simple to set up. Perfect interface to the elk 120 voice/siren card!
    NEIL -- laurel, MD   5/9/2013
    Excellent solution when you need more than just N/O and N/C.
    KEN -- pembroke pines, FL   12/30/2012
    Works well with the ISY99.
    JEFF -- bettendorf, IA   10/5/2012
    Got it to control my loud siren. Works perfectly.
    MICHAEL -- sedona, AZ   9/22/2012
    This was a replacement for a unit that failed. I am stuck replacing these units and a lot of indigo modules because of consistant failures. I have whole house surge protection on several sites, and monitor the power from several high end ups units. The problem is not power, the problem is poor quality control. How about respond ing to this and we can discuss how you are taking a good idea and making it unusable.
    CLAUDIA PATRICI -- hollywood, FL   7/19/2012
    Good, work fantastic, I wish a feedback for each relay active in insteon id this posible?
    VITALY LYSENKO -- doral, FL   12/8/2011
    Works as expected.
    THOMAS -- browns mills, NJ   7/28/2011
    Works as it should, but it is overpriced in my opinion. Other than the price, the unit works fine.
    MATTHEW R -- savannah, GA   7/8/2010
    I use this for irrigation control. I like the safety features -- turn off after x time (even if no command has been issued to turn off). But for only 4 output relays, I find this pricey.
    JOSEPH -- joliet, IL   3/5/2010
    Great product. I love this. Works perfect for wiring a garage door opener. Now I can open the garage from my iPhone with my Mac and Indigo.
    ERIC -- plymouth, MN   1/6/2010
    Device works as expected (a relief given issues with other SimpleHomeNet items). Great service from SmartHome as always!
    sar -- India   8/18/2009
    Successfully Programmed the regular intervals of the Timer
    ERIC -- seabrook, NH   6/29/2009
    Directions are not clear for programing, but I was eventually successful in programing each channel
    JOHN -- black canyon city, AZ   1/11/2009
    Works without fail. Not using the timer settings. Using Homeseer, and had to use a script change some of the coding in it to get this to work with Homeseer.
