Easy install, setup is not as easy, Requires several steps, and is best accomplished by purchasing a powerline modem and free software. Has uses, but did not fit my application.

Haven't installed and tried yet

Can not program the device at all. None of the software can see it.

Instructions are a little convoluted but Setup SW works as advertised and unit performs very well. If you need multiple outputs and inputs in one unit..it's a great choice. Big plus is command set is fully documented.

The instructions are a bit convoluted and its not easy to know which relay you are assigning even if you follow the instructions. e.g. to trigger relay one from Insteon you have to set it into program mode then press once then press and hold for 4-6secs, relay two is press twice and then press and hold 4-6, and trigger both you just press and hold. When you're doing this there is no way to know if it has taken the presses and is assigning it to your specific relay. A dip switch for program assignment or more LEDs would solve this.

The second one sent to me works fine. But the set up and manual is really bad. Not smarthomes fault but worth mentioning.

Outstanding product! Easy to setup (when you read the directions and message boards). Highly recommended!!

I purchased an EZIO for the purpose of integrating my alarm system to my home’s Insteon lighting. Upon receiving the EZIO I was disappointed with the documentation available. Let me preface this statement with the fact that I sell/engineer/program/support commercial building automation systems for a living. I don’t need much information to figure out how to wire something, but connecting the EZIO with the information provided was really a “best guess” for me. The documentation leaves a lot to be desired. After convincing myself that the wiring was correct, I attempted to link the EZIO to my multitude of Switchlinc dimmers and relays. I quickly realized something wasn’t quite right. The first device I linked to an EZIO input would work. However, when I tried the same thing on another input the second input wouldn’t work, and the first stopped working too. It got to the point that once a device was linked to the EZIO, the EZIO would immediately start sending out a flood of Insteon messages (as evidenced by Houselinc Desktop software) crippling all of my Insteon devices. I called Smarthome Technical Support. The individual I spoke with had no idea what I was talking about. He put me on hold to talk to a supervisor, came back and again asked what my issue was. I made the mistake of mentioning that I also used the EZIO software (available from the manufacturer’s website) in an attempt to troubleshoot what was going wrong. Even though my issue had nothing to do with the software, he seized on the opportunity to blow me off and directed me to contact the manufacturer’s support. He provided the phone number and ended the call. I immediately called the phone number provided. The person who answered the phone had absolutely no clue what I was talking about because it was not the right number. That is because I was given the phone number of a contractor in Boston who installs Insteon products instead of the manufacturer! I located a phone number for the Simplehomenet (the EZIO manufacturer) and gave them a call. I need to point out here that their support was stellar. After explaining my situation and the troubleshooting steps that I had performed, they determined that my device did not have the most current firmware version. Even though I did not purchase it from them directly, they asked that I mail it in and they would send out a replacement with the current firmware. The replacement arrived in a few days. Once I received the replacement I was able to quickly hook it up and link it to my lighting. In summary: - Do not purchase the EZIO unless you are confident of your electrical skills. A familiarity with the Insteon command set doesn’t hurt either. - If you need support on this product, don’t bother calling Smarthome. - Once you get it connected and programmed it does work very well.

The EZIO2x4 has excellent features and flexibility, however it also appears to have some serious compatibility flaws. If you are manually linking, you should be fine. Otherwise, BEWARE! After struggling to get it working with my ISY-99i ultimately did not work, I learned that this product has a spotty history working with several INSTEON controllers and software packages. According to Smarthome and UDI, this EZIO does not currently work with ISY. IMO, Smarthome should disclose this fact on the product page. Also, if SHN ever gets around to addressing the problems with this device I will have to send the unit in for reprogramming; the device & software utility provided does not have the capability to re-flash the firmware.

The unit works perfectly, however, the documentation was somewhat difficult to follow and would have benefited from more application examples.
