I have a Harmony 890 and a Intermatic HomeSettings

HA02C
http://www.amazon.com/Intermatic-HA0...ref=pd_cp_hi_2

controlling the florescent light via the Harmony


I'd like to get a motion detector so that when I walk into the HT room the lights turn on, and turn off when I walk out.


I don't have any other z-wave controllers - just the Harmony remote and HA02C module. What do you recommend buying (price is an issue)?

thx

I am under the impression you don't have a whole lot of options. The Z-Wave alliance site shows only 3 companies providing motion sensors: ACT, Intermatic and Hawking. ( http://www.z-wavealliance.org/module...5051b86177a757 )


I don't know this list is comprehensive, but I don't recall seeing Z-Wave motion sensors from other providers (except HomeSeer, which I believe is OEMed from ACT.)


I'd think any of these would be compatible with your existing setup since Z-Wave is a well defined spec at all layers of the stack (unlike ZigBee - at least pre ZigBee Pro.) Intermatic's device is around $50, I believe, and since you already have their lighting controller that sounds like a safe bet.

thanks, what would I use to program it to turn on the light when it senses motion?

Or is there a better option (had bad experience with X10) that I can use with my Harmony 890?

Basically those are the 2 functions that I want

(a) turn lights on when senses motion

(b) switch lights on/off according to scenes set in Harmony Activities.
(edit - oh yeah forgot to mention my light is a florescent "shop light" - not every module works with that without flickering)

thx

I believe that once you register the Z-Wave motion sensor with the Harmony (which acts as the primary controller), the motion sensor will subsequently be able to send ON commands directly to the light switch (assuming it is in range.) Configuring the motion sensor to do this is, I believe, straightforward, but I don't know the exact steps (and it probably varies by manufacturer.)


Z-Wave seems like a reasonable approach to integrated control of A/V, lighting, etc., and I can't think of a better one using your existing Harmony.


A few caveats:


1. Z-Wave may fade away. Even Intermatic seems to be pulling out. http://www.cocoontech.com/forums/ind...=motion+sensor . Something to keep in mind before building out a Z-Wave platform, if that's where you're headed.


2. The Harmony remote is a bit funky as a Z-Wave controller: http://forums.logitech.com/logitech/...hread.id=33420

Great info.

regarding Z-Wave - basically the 890 dictated my choice. And since I'm just using these 2 devices the investment is not that major.

I see in the Harmony s/w how to set Z-wave devices together with scenes on the remote. Does it also allow you to tell one z-wave device (appliance module) what to do when commanded by another z-wave device (e.g. Motion Sensor) - i.e. without pressing the remote to turn the light on. I just want to double check before buying as I just don't see the option for that.

I am not certain on this point, but I believe you can associate the motion sensor with the light switch without involving the Harmony software (though the Harmony would still be involved in getting the motion sensor on your Z-Wave network, since it is the primary Z-Wave controller.) Instructions for configuring this association would (hopefully) be provided by the motion sensor device manufacture.


Sorry I can't help you take this home. Perhaps someone on cocoontech.com might?
