RGB LED strip and json Topic is solved

[franzelare]

did you already figure out how to do this?

[gizmocuz]

Something like

[url]http://IPADDRESS:PORT/json.htm?type=command&param=setcolbrightnessvalue&idx=224&hex=FF00FF&brightness=100&iswhite=false[/url]

The hex value didn't work, I get an error back
I checked the topic and tested a bit, only had to convert the values from HUE lights before I could feed them back in to domoticz, but now I can set the led strip using json commands and a bash script.

only on a synology I get a timeout when I try to directly execute the command
so I have a work around now by calling a bash script from the lua script to change the led strip

[franzelare]

you can also add &saturation= to complete the command set

hmmm, when looking into detail, I don't get the same color on the LED strip when I put in the hue/sat/bri as when I use the rgb values in domoticz
but when I send the same values to the hue lamp, the colors stay the same, so there is no color conversion mistake before i put the data in
and the hex command doesn't seem to work
gizmocuz: is the hex command supported in all versions? since my nas is still running an older version..

[gizmocuz]

I think it is supported in the last 300 versions.... for sure from the latest stable version
Maybe i got the command wrong.. do you get an error when you enter the json url in the browser ?
It should work, it converts internally the hex to hue again...

[franzelare]

Ah, that's the trick, from a new release that I run on a Pi I can send hex code
but there is a mistake in the hex string send

when I send FF00FF in the hex string, the string recieved by the device is FF00FBrsion
String hexstring = message.getString();
Serial.println(hexstring);

so Blue is not correct al the time due to the string send
like FF000F will end up as FF0011rsion

now I also see why I get the wrong values when I send hue sat and bri to the RGB strip
(this is now in release 3.4834)

As the last post is around two years old, and it seems the "bug" is not fixed - is something else wrong with "setcolbrightnessvalue"?

No matter if send through browser or Domoticz script, f.e.

Code: Select all

http://192.168.178.200:8080/json.htm?type=command&param=setcolbrightnessvalue&idx=51&hex=000000

results in

Code: Select all

TSF:MSG:READ,0-0-1,s=1,c=1,t=40,pt=0,l=6,sg=0:FFFFFF

only FFFFFF is transmitted fine, every other hex value is somehow converted. Also tried brightness and so on, does not seem to make a difference.

EDIT: as it is all about JSON:

Code: Select all

http://192.168.178.200:8080/json.htm?type=command&param=setcolbrightnessvalue&idx=51&color={"m":3,"t":0,"r":0,"g":0,"b":50,"cw":0,"ww":0}&brightness=100

f.e results in status "ERR" - it is an exact copy of the JSON example on the Domotics wiki

EDIT 2 :

Also, choosing a value from the color table in Domoticz results in false hex value received by the node -.-

One question.
How you send this "http" call from MySensors for example radionode ???
