KNX: Add RGB and Dimming Control

[goofy79]

PROBLEM DESCRIPTION

I think the KNX Settings for the RGB Module doesn't work ?
I have Arilux LC01 Modul with the Tasmota Version 8.1.0.
In the KNX Settings, i can choose KNX RX 1 - KNX RX 5
But it doesn't matter what data i send to the Inputs - the Color and the brightness
won't change.

TO REPRODUCE

Set KNX Group Addresses with ETS - than set the Groupaddresses the receive Date an send any data to this Groupaddresses.
My Groupaddresses are
3/3/70 -> Output 1 On/Off (work)
3/3/71 -> KNX RX 1 (won't work with any data)
3/3/72 -> KNX RX 2 (won't work with any data)
3/3/73 -> KNX RX 3 (won't work with any data)
3/3/74 -> KNX RX 4 (won't work with any data)
3/3/75 -> KNX RX 5 (won't work with any data)

EXPECTED BEHAVIOUR

I expected that, if i send a value between 0-255 the the KNX RX 1-3 the Color of the RGB Stripe will change. So KNX RX 1 for Red - KNX RX 2 for Green - KNX RX 3 for Blue - KNX RX 4 maybe for brightness and KNX RX 5 for the last control.
So i can change the color with a string linke
0/0/255 for Blue
255/0/255 for Pink
and so on ...

I think the Values are there
16:43:56 RSL: RESULT = {"POWER":"AN","Dimmer":89,"Color":"00E38F","HSBColor":"158,100,89","Channel":[0,89,56]}
the only thing to do is, to set the received values from the KNX objects to the right variables, isn't it ?

SCREENSHOTS

ADDITIONAL CONTEXT

nothing at the moment

(Please, remember to close the issue when the problem has been addressed)

[ascillato]

KnxRx slots are meant to be used with rules. See wiki and docs at KNX chapter on how to use knx rules triggers. If you send the color separated in channels, you should be able to set rules to use them and set the colors in Tasmota.

If the command you are sending is the DPT for color, it is not supported by now.

[goofy79]

Ok - is this planed ?
i tried

rule1 1
rule1 on event#knxrx_val1 do Var1 %value% endon
rule1 + on event#knxrx_val2 do Var2 %value% endon
rule1 + on event#knxrx_val3 do Var3 %value% endon
rule1 + on event#knxrx_val5 do Dimmer %value% endon
rule1 + on Var1#State do Color1 %Var1%,%Var2%,%Var3% endon
rule1 + on Var2#State do Color1 %Var1%,%Var2%,%Var3% endon
rule1 + on Var3#State do Color1 %Var1%,%Var2%,%Var3% endon

18:38:52 KNX: Received from 3.3.71 Command Write: 41943.04 to KNX RX 1
18:38:52 RSL: stat/tasmota/RESULT = {"Event":"Done"}
18:38:53 RUL: EVENT#KNXRX_VAL1 performs "var1 41943.0"
18:38:53 RSL: stat/tasmota/RESULT = {"Var1":"41943.0"}
18:38:53 RUL: VAR1#STATE performs "Color1 41943.0,10.24,41943.0"
18:38:53 RSL: stat/tasmota/RESULT = {"POWER":"ON","Dimmer":84,"Color":"215,71,215","HSBColor":"300,95,84","Channel":[84,4,84]}

But i send for example the Value 100 to the Object and 41943 / 215 arrives ?
If i send 10 - 10,96 (10) arrives / if i send 50 - 327.68 arrives ?

18:40:34 RUL: EVENT#KNXRX_VAL2 performs "var2 327.68"
18:40:34 RSL: stat/tasmota/RESULT = {"Var2":"327.68"}
18:40:34 RUL: VAR2#STATE performs "Color1 41943.0,327.68,41943.0"
18:40:34 RSL: stat/tasmota/RESULT = {"POWER":"ON","Dimmer":84,"Color":"215,71,215","HSBColor":"300,67,84","Channel":[84,28,84]}

Whats wrong with my rule ?
Thank you so much

[ascillato2]

Hi, yes, it is planned to be added. I have to find some time to do it.

About your rule. Your rule is ok. The issue is the DPT your KNX system is using to send that value that is not what Tasmota expects. Try to change the DPT. If you can't you will have to wait until Color DPT support is added to the Tasmota KNX driver.

[goofy79]

can you tell me what kind of DPT the Tasmota driver expected ?
Actual i send 5.005 Decimal (0-255)

[ascillato2]

Yes, sorry, Tasmota expects DPT 9 (2 bytes float) for recepted values. I have to add that information to the docs. Thanks.

[goofy79]

puh, that's heavy - to convert a 0-255 RGB value in KNX to a 2 Byte Float.
my Visu send, for example, a 1-Byte value per Color

perfect will be, if you can set the datatype for receiving ^^

PS: if you need somebody to test - feel free to write 👍

[JohannesRegner]

Hi, i have the same problem! I'm using an Gira X1 KNX Visua Server, and tryed to change the color via GUI, but i can only switch on/off.
I think, the problem is the same as @goofy79 described ...

if you need any support/testing, I can also help!

[ascillato2]

From #8084, also add Dimming control.

From #10333 also DPT Selection

[fluppie]

+1 I was also looking for this func. I can switch the LED strip on and off, but also want to regulate the brightness with the KNX switches.

[JackyKNX]

+1 more ;) Is there any chance to get it soon ?

[jpirnay]

+1, I do have some tasmota driven LED strips that would definitely benefit from this!

[edvandreas]

+1, I would also like to get this implemented

[Jaegerstefan]

+1 It would be really helpful to get this working.

[eldi0s]

Definitely +1

I wonder how DPT9 could make it while DPT5 did not ;-)

[Adminius]

Hey, any news?
I will also use Tasmota (H801 and Sonoff B1 Bulb) with my KNX installation with the dimmer functionality (long press on a button for change the brightness).
I also tried https://github.com/ascillato/Tasmota_KNX/releases/tag/v9.3.1.2
but without success:
If I send 100% DPT 5.001 via ETS (255/FF value) I get this:
21:30:43.576 KNX: Received from 4.3.14 Command Write: null to KNX RX 1
If I send 50%:
21:31:29.520 KNX: Received from 4.3.14 Command Write: -0.00 to KNX RX 1
and with 0%:
21:31:59.322 KNX: Received from 4.3.14 Command Write: 0.00 to KNX RX 1

[ascillato]

Hi, it is not supported at this moment, sorry. I have to find some time to code it.

[tetzlav]

Its not clear and i dont find any official documentation to this:
Does Tasmota supports dimming control via knx?
And if so what datapoint are used? (relative 3-bit DP3.007 or absolute 8-bit unsigned DP5.001)

[Turtle051987]

Hi, it seems like the changes have not been implemented for Version 14. As the absolute dimming is working I want to ask if it's possible to add this festure for the next release.

[arendst]

Try latest dev.

[barbudor]

@Turtle051987
Sorry I was late to push the updated code to Tasmota
I did that only yesterday so it missed the new release. Still available in dev as pointed by Theo

[Laudi111]

@barbudor: At first, thank you for the KNX dimming extension.

I'm current testing KNX dimming with Tasmota Release 14.2 and i had some problems.
I use a Shelly RGBW2 in configuration "white Option (setoption68)" with 4 white LED strips and i want to control the brightness of every LED strip.

When i change the Brightness over KNX, the "Bright" value changes in Tasmota console view, but it doesn't take effect on the brightness slider on any one of the 4 channels. I think its seems to be a problem because of 4 channels and not RGBW configuration. Is it possible to get a knx brightness value for every channel instead of color?

If i change the "Color" over KNX, the 4 channels become updated with the "color" value.
But it looks like a problem with the 4th "W"-channel, it's limited to the value 64 when receiving a value over KNX. In web-interface i can slide it to 255 and the value is also sent back to KNX. But when i'm sending $FF on all 4 channel over KNX, the first 3 channels are set to maximum but the fourth ist set to $3F. Can you check this behavior?

[barbudor]

@Laudi111 the KNX implementation is meant for Light mode of Tasmota, not separated PWM channels
You might be luckier using the TX/RX modes with rules
But I'm not a KNX user myself, just did some coding to help
