REST Control of COLOR_SWITCH

[Niick_W]

I have a HSM200 that I just set up. This is a Zwave RGB light with various sensors (Motion, lux, temp). Lux and Temp report OK, but I'm looking for some guidance on how to control the light.

In Admin Console, I have a device ZW005_186 which is the COLOR_SWITCH control. It shows three values, R, G and B. For some reason there are three buttons, "fade up", "fade down" and "fade stop", for each of which I can pick a channel (red, green, blue). Clicking on these increases the red/green/blue channel up or down 1 value (and the light responds). So it works, but you can't really set a colour this way.

There are three properties reported, GV2, GV3, and GV4 which correspond like this:

ZW 005 Color Switch/GV4 0   #blue
ZW 005 Color Switch/GV3 0   #green
ZW 005 Color Switch/GV2 0   #red

This is the output of `/rest/zwave/node/ZW005_186/def/get`

I would like to set the RGB value using the REST interface, but so far I can't find any combination of commands that changes anything for this node.

Can anyone shed some light on how to set GV2,3,4 via REST?

Thanks.

 

UPDATE:

Had a brainwave after posting this, and finally figured it out.

The REST command is `/rest/nodes/ZW005_186/cmd/DON?GV2=0&GV3=255&GV4=0` which sets r=0, g=255, b=0 (ie green) or any other rgb combinations. And it works!

Hope this helps someone else out.

This is really cool. I'm thinking about picking up a couple of these. Did it work out of the box or did you have to set any config parameters to get the sensors working / reporting correctly?

I don't believe I had to do anything. This is a bit of an oddball device though. You can only set 7 colours (ie you can't set any RGB combination, only 7 are allowed). The device has a light sensor, but also emits light - so the sensor picks up it's own light output - weird!
