Can two Z-Wave networks co-exist? For example, if I have one network in a theater room controlled by a Logitech Harmony 890 (which apparently doesn’t like being a secondary controller from what I’ve read on forums) to do lighting in that room only and a second controller (i.e. Vera) set up as a primary controller to control functions in the rest of the house (but not the theater room) would the communication between Z-Wave devices get confused?

The answer to question is a definitive yes. A primary controller creates a unique network ID. What you have read is correct: the 890 doesn’t play well with others. If you have the 890 Standard then it can only act as a primary controller. If you have the 890Pro then it acts as a primary or secondary to another 890Pro.

With what you explained, the 890 (primary controller) will control the theater room and the devices in that room. And the Vera box with the Z-Wave dongle (primary controller) will control the rest of the devices included with the dongle/Z-stick.


I am interested in a Z-Wave solution for my home. I was just wondering how a Z-Wave controller actually changes the channel on my TV or changes the sound field on my Denon AVR3808. I know Z-Wave uses radio frequencies but how does that change to IR? My TV is only IR and my Denon amp does have a remote input and RS232 control but how does a Z-Wave controller control that? Does it have a database of thousands of device that I program in each piece of equipment?

The Z-Wave Controller doesn’t actually change or control your TVs or your amplifiers. The remote has a Z-Wave chip in it that controls the Z-Wave devices. It controls audio and video components the same way by learning the IR codes of the device the Nevo S70 and Q50 remotes do Z-Wave, IR and Wi-Fi Control. These are the Rolls Royce of handheld controllers.

There are other controllers on the market like the GE 45608 Home Theater Remote with Z-Wave Lighting Control. But it probably doesn’t have as extensive an IR Library as the Nevo.

Another solution is a hardware/software controller like HomeSeer, which allows you to tie all the different aspects of your automation through the software including audio/video, temperature control, lighting control, door locks, security, and cameras.


Can I use the Schlage Bridge, connecting to their thermostat with software that doesn’t require a $12.99/month subscription? What software would you recommend?

If I understand what you are saying is you want to be able to control the TZEMT400AB32MA Z-Wave Thermostat without having to use the bridge. There are a couple of options to consider.

Vera  — There is no monthly subscription to access the system. It can communicate with thermostats, locks, motion sensors, temperature sensors, and lighting. The Schlage Bridge is not capable of working with sensors yet. Check out the Device Compatibility Chart for the Bridge.

HomeSeer — There is no monthly subscription to access the system. Vera has been on the market a little more than a year. HomeSeer has been on the market for 11 years and has been working with Z-Wave since 2003.


I have an HA 7 Controller, and can’t seem to get it to control the ZDP100. I can get it on to the network, but I can’t get it paired to a channel. Can this be done?

Yes, the ZDP100 is compatible with the HA07C Controller. How many devices do you have on/in your network? Have you tried pairing the ZDP100 to a different channel? If so, what happened? I have had this happen a couple of times with the HA07C Controller and had to do a system reset on the controller and redo the network. The HA07C Controller is one of the first Z-Wave Controllers that came on the market. Intermatic/HomeSetting discontinued the manufacture of Z-Wave products about a year ago and exited the market except for warranty work.
