  • The ISY994i/IR Pro 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/IR Pro supports up to 1,024 devices and scenes and a maximum of 1,000 programs. The ISY994i/IR Pro 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. The IR model allows you to program your infrared universal remote to control all your Insteon /X10 devices and scenes. The PRO model extends the capabilities of the ISY for extremely large installations.

    Insteon Control

    For Insteon control this device must be paried with an Insteon Dual-Band PLM Serial Interface. The PLM allows for direct communication with your existing Insteon network from the ISY994i/IR Pro 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 Mini Remote, Thermostat, Motion Sensor, Open/Close 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 ISY994i Series

    • An expansion slot which could be utilized to install and support other protocols such as a Zigbee or Z-Wave
    • 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)
    • Non IR models can be field upgraded to IR platform

    Please Note

    ISY994i/IR Pro 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 2413S).

    Using any Java-enabled web browser, the ISY994i/IR Pro gives you the ability to control, monitor and configure all Insteon-compatible devices from any web-browser anywhere in the world. Best of all, no software is needed to gain access to your Insteon network. Simply bring up a browser and type in the URL of your Home Automation Controller.

    Rock-solid, powerful and reliable Review by Randy S.
    Rock-solid, powerful and reliable

    I've had two of these units (main home and vacation home) for the past five years.

    This is the controller you want to get if you're serious about doing real stuff with Insteon and Z-Wave. Yes, the admin console is currently based on Java (if you want a rich, desktop-style app user interface) but there is also a browser-based UI that works fine; it's just not as sophisticated as the Java application. They've improved the launcher in the last few months also; now it automatically queries the ISY you're logging onto and gets the appropriate version of the Java admin console app so there aren't problems anymore with having mismatched versions of the firmware in the ISY and the Java admin console app.

    This unit is capable of real-world tasks that few, if any, other automation controllers can handle. For example, I have some Insteon water leakage detectors near my water heater, well pressure tank, and other places in my basement that might be prone to water leaks. The ISY is capable of the kind of programming necessary to monitor the "heartbeat" signal that the leakage detectors send out once per day to indicate they're alive and well. (They're battery-powered, so you want to be able to monitor them.) If the program running in the ISY hasn't received a "heartbeat" in the last 24 hours, it sends a text to my phone letting me know.

    I also have an Insteon thermostat in my vacation home. Once a day, the ISY unit I have there sends me a status report to my phone with the current house temperature and other vitals. It notifies me if the burglar or fire alarm is sounding, or if the temperature drops below a certain point in the house.

    Finally, one of its best features (in my opinion) is that the ISY keeps its own database of all the links between your Insteon devices (scenes, etc.) and independently verifies them to ensure your Insteon network is "whole" with no missing links. It can then query the link table in any of your Insteon devices and compare that table to the one in its own database, and if there's a mismatch, the ISY can "reach out" to the Insteon device and sync up the device link table with the ISY one. (When programming a whole house of Insteon devices over the network, it is common to have a glitch now and then that results in the link table in a given Insteon device not being set quite correctly.)

    A lot of thought and effort has been put into the design of this device. If you want rock-solid reliability of your Insteon network and the ability to do some serious, real-world applications, this is the best unit out there. And there's an active set of web forums where people share the programs they've developed to do various things. The lead developer of the ISY also participates on these forums.

    Works well Java access software updates are a real PITA. Review by MevetS
    Works well Java access software updates are a real PITA.

    The software works well although if you ever getting into trying to program things, it is severely limited by having to use the most basic of logic. Makes writing a program a much more complex task then it should be.

    But the biggest PITA with this system is the updating of the code for the Administrative Console. It's more of a pain than it's worth, at times. I've had updates work flawlessly and then again, I've had to repeat the update numerous times. You never know. Often it is is supposed to be because of the Firewall being left on. I'm still trying to get the latest update to work and I have several devices to add and integrate. I guess I'll have to write a support ticket. Unfortunate, since otherwise, this is a very reliable and functional system.

    Happy Review by MrBates1313

    The controller gets 5 stars. I had a problem getting the PLM working but read some reviews and followed the procedure to power all down, wait 30s, power PLM up, wait 30s, power controller up. That has been working now for a month. Haven't had any power failures so we will see what happens when I do. Hopefully the tech support is right and it should all work fine. We will see.....

    Not Reliable Review by John
    Not Reliable

    I invested in this controller a couple of years ago when Smarthome discontinued supporting their HouseLinc software. It's not easy to program, and I found it very unreliable. I had to install an Insteon on/off module on the power cord to the ISY so that I could power off the ISY from an Insteon hub and re-power it, whenever the ISY controller would lock up. Telephone support, which Smarthome had promised would be quick and thorough turned out to be a "don't call us, we'll call you... several days later." They could offer no solution for why the ISY was locking up.

    The final straw came a couple of days before we were heading out on vacation, when suddenly the ISY turned everything on (all 60+ Insteon controlled lights and fans). At that point I pulled the plug in the ISY and went back to using HouseLinc. I wish they still supported HouseLinc... it had features the ISY doesn't have, and it actually works.

    Love the unit Review by Donald
    Love the unit

    I've had it for a month now and love it. Had a house full of X-10 modules with Adcon and the Leopard, however this is much more reliable with Insteon. This unit working with X-10's is marginal, not very reliable, most probably cause is probably the fact they are not designed to work with LED's.
    As far as support, Steve is the best, he knows it all and is a great asset to the system.

    Finaly a reliable controller ! Review by Sam Beigi
    Finaly a reliable controller !

    Tried the insteon hub first and had to switch to this controller. Reliable and performs well. Could use a better interface but overall a great product.

    Review of ISY994i Review by Ryan
    Review of ISY994i

    Have had this controller for over two years now and can report that it is absolutely rock solid in its performance. I have just over fifty devices (mostly light/outlet switches and garage doors sensors) and it hasn't missed a beat. I use the programmatic feature significantly. If my garage doors are open for more than ten minutes, my wife and I get a text notifying us (great if we forget to close either bay). If the fireplace has been on for over two hours, same thing there - very nice in case we walk out and forget to turn it off. Also have programs running for the bathroom fans. When the light is turned on, I have the fan turn on - when the light is flipped off, the fan stays on for another five minutes before turning off.

    Really appreciate the fact that it has the NTP (network time protocol) feature so it's time stays accurate (a significant problem with earlier controller models). Also slick that it adjusts sunrise and sunset depending on your location - living in the Pacific Northwest, that change can be several minutes a day.

    All in all a I'm quite pleased with this unit. My only reason for not giving it a five star rating is that it can be somewhat confusing at times when defining devices. Don't get me wrong, it is a quantum leap over doing it manually, but I've seen other posts regarding controller/responder settings and I agree that can take a little getting used to depending on what you're trying to accomplish. I wouldn't let that stop you though - this controller is exactly what you need if you're at all in to home automation.
