  • What's Included
  • The ISY994iZw 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 ISY994iZw is your controller.

    This controller now features Z-Wave technology to automate home control products and provide easy remote operation of all your Z-Wave enabled devices. The Z-Wave product family includes a variety of devices ranging from lighting to home security systems to conveniently manage your home. This controller is one component of a Z-Wave control and is designed to work with all other Z-Wave enabled devices in a home automation network. It will also act as a wireless repeater to insure that commands intended for another device in the network are received, thereby extending the range of the wireless controller.

    This module provides ISY support for Z-Wave in a way that integrates with other protocols running on the same ISY.

    The ISY994iZw supports up to 256 devices and scenes and a maximum of 300 programs. The ISY994iZw 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.

    Insteon Control

    For Insteon control this device must be paired with an Insteon Dual-Band PLM Serial Interface (included). The PLM allows for direct communication with your existing Insteon network from the ISY994iZwR 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, Contact Sensor.

    Additional Features

    • IR Control - Control all your Insteon/X10 devices with any infrared universal remote (RC5-compatible)
    • 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

    Extends the capabilities of the ISY994i 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 ISY994iZw does not require a power supply when used with a PLM (included) which supplies power via the RJ-45 port. ISY994iZw 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 ISY994iZw 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.

    Second time I've installed one of these... Review by smacbride
    Second time I've installed one of these...

    This is the second house I've setup with this ISY/PLM combination. I've had nothing but a good experience with these. The interface could use some improvement, but I found it overall pretty easy to figure out and use. I had a few issues but the folks at Universal Devices were on the spot in helping figure some things out.

    Both houses use a mix of Insteon and z-wave. I have the MobiLinc app on my apple devices and I use that pretty exclusively for controlling both homes.

    Finally! A hub that works! Review by Greg
    Finally! A hub that works!

    I bought this hub to replace my problematic Insteon hub. Although this unit requires a small amount of programming to have it do what you wish, it is not hard. The unit is rock-solid and has many more capabilities as compared to the Insteon hub. Tech support is also great.

    Not intuitive software and difficult to program...and is not reliable. Review by Big Bird
    Not intuitive software and difficult to program...and is not reliable.

    I have been an Insteon user from the beginning. I have set up 2 houses, each with over 60 devices of all types. I finally got an ISY since it has more versatility than the Hub. After spending some 10-12 hours with the ISY software I have given up. The UI is simply not intuitive and the manuals are incomplete. There are different help files that you must find in order to set up various things, and unless you are familiar with the software there is a steep learning curve...and this is from a person who definitely knows Insteon, For example, to make a set of medium/dim buttons you have to go into a menu that advises you not to use it, and then discover a pretty much undocumented way to make one button off when you turn the other on. I diligently read the manuals, but this feature simply didn't work reliably. I started out by resetting every device I had and started fresh so there were no previous links, etc. Also, the PLM doesn't seem as robust as the Hub. I have had no noise or difficult communications with the Hub, but the PLM had intermittent difficult writing to a device that it wrote to a few minutes before. Overall, I think that the software is the Achilles heal of the ISY. It has the promise of a versatile and robust system, but it just wouldn't work reliably for me and unless you really need something it will do and the Hub won't, the Hub is much easier and reliable. I used to design software, and when I look at the UI of this it feels like the programmers just didn't do a good job of designing it for ease of use.
    I'm returning the ISY & PLM.

    ISY is very very powerful and reliable, not necessarily easy Review by d4nimal
    ISY is very very powerful and reliable, not necessarily easy

    Other reviewer's comment--that the UI is terrible (uses Java) is right-on. That said, this device is extremely powerful and if you want to get under the hood of your home automation, this is the thing you need. I've been a huge fan for five years of the ISY, and that was after years of resisting a friend's urging to get one to solve a slew of one-off problems I had had. With the ISY, I NEVER find myself saying "I wish I could do that." It does everything. Turn on Sonos music from a keypad? Check. Have the house run a complex and variable set of lights when on vacation? Check. Turn off all automation with a single button to avoid scaring someone new to the house? Check. Take actions in response to doors opening, motion, alarm arm/disarm? Check. None of these things was built-in, but all were doable with the ISY--and with other products, you have no option.

    Good Product Review by PCRover
    Good Product

    Nice reliable controller with easy to use software. Once you get the hang of the programming it is a breeze. It is lacking in the stock web interface, but it does the job. The iPhone app is great but the Android version lacks some features. I couldn't deal with my Vera-3 any longer and decided to try this controller and I am happy I did. Good by Vera you will not be missed.

    Interesting, but needs some work Review by ronk127
    Interesting, but needs some work

    First off I would like to say that this device is NOT intuitive, and I have struggled to get it to work smoothly for over a day now. I am a software engineer, so I do have experience in the field of interfaces, functionality, etc..
    While it does work, getting it to that point is a bit of a chore, and even with a $350 device, I find myself still having to link insteon devices the old fashioned way to get the desired functionality (or you can use Houselinc).
    The software that is used for this is TERRIBLE. Not intuitive, creates unneeded complexity in what should be simple procedures, often crashes (busy loops, can't exit, can't figure out why things won't work, then reboot, and will work for 15 more minutes), and least of all it looks like a high schooler wrote the UI. Seriously guys, for $350, invest in a UI designer and think about some typical Use cases to help design the look, flow, and professional feel of your software.

    Apart from the endless frustrations though, I will say it does work. I am just finding myself dreading having to open the software up every time.
