Essential Info

The ISY994i is one of the most advanced INSTEON controllers on the market and has numerous features to satisfy the most advanced DIY'er or seasoned home control enthusiast. If you need unbridled control, the ISY994i is your controller.

The ISY994i supports up to 256 devices and scenes and a maximum of 300 programs. The ISY994i controller is able to configure and program INSTEON devices using INSTEON native protocols and specifications. This allows it to directly write to INSTEON devices internally instead of just in the controller, creating a more robust network. You can set up timer events and custom event triggers, as well as monitor and control all the INSTEON-compatible devices in your home from any web-browser anywhere in the world. Now you can check if the lights in your house were left on and remotely control them from your computer at the office.

This kit includes an INSTEON Dual-Band PLM Serial Interface, allowing for direct communication with your existing INSTEON network from the ISY-99i controller. The PLM features built-in dual-band technology that sends and receives INSTEON signals via powerline and radio frequency (RF), so it doubles as an Access Point. This makes it ideal for new INSTEON installs if you have or plan to use an RF-only INSTEON-compatible devices like a remote, thermostat, motion sensor or contact sensor.

Additional Features:
  • Control other network-enabled devices using an optional Network Module (RS-232 devices can be controlled using an ELK IP232 or Global Cache GC-100 and more)
  • Can be field upgraded to IR platform

  • Extends the capabilities of the ISY99i Series
  • An expansion slot which could be utilized to install and support other protocols such as a Zigbee
  • Increased code memory to support additional communications drivers
  • Native support for Open ADR out of the box

  • Please Note:
  • The ISY994i does not require a power supply when used with a PLM which supplies power via the RJ-45 port (for example, PLM model #2412S). ISY994i does provide a port for an optional AC adapter for instances where the PLM does not supply power, or the user prefers to supply power independent of the PLM (for example, PLM model #2413S).

    Great product, a little trouble getting it going but ISY's support was terrific and even solved the problem on a Sunday!
    JON -- cuyahoga falls, OH   2/20/2014
    This is THE controller to have for Insteon products. Very flexible and reliable. Complex to program, but worth the trouble.
    FRANK -- san antonio, TX   1/10/2014
    Some time ago I bought an ISY994i/PLM combination to replace an older technology controller which had been fried during a serious electrical event. It works so well that when SmartHome offered it for half price I bought it immediately as a gift for one of my daughters.
    et . -- Alaska   1/10/2014
    I DO NOT RECOMMEND PURCHASING THIS PRODUCT. It is not mature enough for mainstream. They advertise access from anywhere in the world, but that is only if you have a DLink model DI-6xx router. Otherwise you are on your own. It will work with MobiLinc to access, but not to configure the controller remotely. And for this you have to pay a fee to download MobiLinc Pro, and a monthly fee for MobiLinc Connect.
    WILLIAM -- ocala, FL   12/16/2013
    Sale went as expected - paced the order - recieved order, no problems
    LES -- washington boro, PA   12/15/2013
    The equipment is fine.
    R STEPHEN -- west linn, OR   11/28/2013
    I had a SmartLinc 2412N powering my home system previously. After it died, I looked around for a replacement and settled on the ISY994i. After a little work getting it set up, it has performed flawlessly. The ISY994i is more of an industrial strength unit than the 2412n. I doubt that I'll ever use all of it's features, but I'm very pleased at how it's performed so far. It came with very minimal instructions in the box. You have to go to the website to download the user's manual. This unit is a bit spendy, but it will be a good investment if it holds up.
    DAVID -- new canaan, CT   11/27/2013
    After having a series of #2413 controllers become unstable after 20 months, I spent 3x to replace with the ISY 994 for my 20 node Insteon control network. It feels like overkill but the programming is much more bespoke and as long as it lasts >3x as long I will be very pleased. Good integration with smartphone via Mobilinc Pro.
    dcrashdummy64 -- central valley, California   11/27/2013
    Don't expect a simple outta the box an it works setup, however, the hour or so it takes to link and start using is lots of fun. Really recommend the Dashboard after the initial setup for controlling from the PC. The wife likes that much better. Support is great, the Universal Device forum has all the answers and is great resource. The product is solid, simple and works. What more could you ask.
    MARTHA J -- columbia, MO   11/9/2013
    The isy994i is an excellent and powerful controller. However, the installation was difficult and very time consuming. Especially setting up my iPhone with the Mobilinc app. In conclusion, it was worth the trouble.
    MICHAEL -- newbury, NH   11/4/2013
    I use the isy994i with the optional x-10 module to control 30 x-10 lighting circuits and other devices when I'm at home and away. It works as advertised and it works well. The programing is easy (and fun), and the tech support is also good. I recommend this product.
    DAVID G. -- stony brook, NY   11/3/2013
    I found this product difficult to program. It was only with the help of a Smarthome technician that I was able to use it. I think it should be made clear in the description that it is not a Smarthome product.
    LOUIS -- alexandria, VA   10/25/2013
    Fantastic system, capabilty exceeds my needs but I'm confident I can expand my security environment with minimum fuss. UDI customer support was exceptional!
    ROBERT -- coto de caza, CA   10/23/2013
    All in all close to a 5 star EXCEPT for the Java requirement and having to launch the administrator from a browser and not close the browser until completely done using the Admin program. Also a second log in is annoying for the admin program and its look is old fashioned [no drag drop, etc.] and it’s really ugly. The new INSTEON Hub has a much nicer interface and does a better job of finding devices but unfortunately lacks some essential features. The INSTEON Hub’s signal must have been stronger as I had to relocate one of my access points to get the ISY994i’s signal to reach devices that the new INSTEON Hub was able to control whereas the ISY994i and its included Dual-Band PLMwas not. It does have the feature set I need just wish it had a more up to date and intuitive interface.
    ROBERT -- atascadero, CA   10/4/2013
    Smarthome, Your patient and helpful support personnel, try as they might, could not get the ISY to link with my devices. However, they did provide me with info to contact Universal Devices people and they quickly diagnosed the problem, got the devices to link, and the system has performed flawlessly since. Thanks
    Ryan S. -- seattle, WA   9/19/2013
    Forget the other controllers, this is the one. I highly recommend it. Have had this up and running for about six months now with no issues. Had the now discontinued PowerlLinc 2412S controller for a year or so and was incredibly frustrated with it limited capabilities, lost clock time, would lock up – had to power cycle it often not ready for prime time at all – no wonder they discontinued it. This one is rock solid. You don’t have to be a programmer but if you like that kind of thing, it supports some basic statements that significantly expand your controlling options if-then-else conditional statements, wait, repeat, etc.. There are some modules available for purchase that further increase functionality utility monitors, weather, etc.. I purchased a module that allows you to easily connect from anywhere using Mobilinc Pro from phone, tab, laptop, whatever – and no worries about your leased home IP address changing. Very slick and very fast response – no noticeable lag from the time I hit the scene on my phone to the time the scene changes in my house. I even tried it from 35,000 feet! Was on a domestic cross country flight using go-go wi-fi and started turning lights on and off in my house from my tablet. I posted on Facebook that I was having the ultimate geek experience – a few minutes later my wife responded with a post: “ok honey, that’s enough…”
    MICHAEL -- middletown, NJ   9/2/2013
    Excellent device. Definitely recommended for any Insteon setup of more than a couple devices.
    ROBERT -- henderson, NV   8/30/2013
    A great place to shop for your home needs. Great customer support.
    HOWARD -- valley village, CA   8/18/2013
    This device is rock solid. I had been using Houselink and suffering through Windows weekly updates making my computer unavailable to function as a dedicated controller. This meant of course that timed or daily events didn't occur as planned. This tiny controller's minimal footprint & online browser access is just so simple to install where needed makes it set & forget. I wish I had simply gotten it dor the original install a year ago!
    CURTIS -- canon city, CO   8/10/2013
    I purchased this after a SmartLinc failed after only a little over a year, and less than stellar reviews of the Insteon hub. It's more expensive than the other products, but if it lasts, the value will be greater. I've now had it installed about a month and so far, so good. Programming in some ways is not as intuitive as the Smartlinc, but not difficult after a few minutes with the user manual.
