Hue Brightness feedback

[NKereshki]

Hello. 

A few months ago, I integrated Philips Hue lighting fixtures that support dimming, color temperature change, and RGB. Everything works perfectly, except I hadn't set up the feedback for the light fixture's state if you change it from the Philips Hue app. Before posting on the forum, I carefully reviewed all topics related to this issue. I am using "user.hue v5.lua" and "resident hue feedback v2.lua". The on/off, dimming, and RGB feedback work perfectly. However, neither the color temperature change itself nor its feedback are working correctly. For example, I set 2000K from W4K, and in the Hue app, it shows a completely different color. The feedback also doesn't work. When I disable the feedback script, the color temperature control works correctly. I am using the following script. Please help me find where I am going wrong. I have spent over 2 days on this problem without a resolution.

Regards, 
Nayden 

Code:

-- Set name (Lookup in HUE app under light configuration) and feedback adresses (don't change statevalue, brivalue and colorvalue as they are used as memoryfield)
addressmapping = {
  -- Name                  -- On/Off FB       -- Bright FB   -- Color FB
  ['Cove lighting-cr'] = {state = '1/0/9', bri = '32/2/9', rgb = '32/3/9', ct = '32/4/9', statevalue = '', brivalue = '', colorvalue = '', ctvalue = ''}
}

-- Set polling interval in seconds
interval = 1

-- Use logging
logging = false

-- loop indefenitly

  reply = getHueLights()

Hello,

I'm noticing that when I change the color temperature, the RGB parameter also changes.

Post your whole script. What is at line 143? Log the current_color_value variable value.

[NKereshki]

Post your whole script. What is at line 143? Log the current_color_value variable value.

Apologies, but those errors were from the previous script I was testing. I uploaded the new one at 4:10 PM, and its last line is number 132.

[admin]

In this case log mylamps variable value after line 20.

[NKereshki]

In this case log mylamps variable value after line 20.

Apologize in advance, but I'm not sure I understood exactly what I need to do.

[Daniel]

add log(mylamps) after line 20 in your script

[NKereshki]

add log(mylamps) after line 20 in your script

Hello,

After I inserted log(mylamps)  after line 20 in my script, the result is:

I don't see the light fixture 'Cove lighting-cr' with ID number 12 in the log file at all.

Best regards,
Nayden

[admin]

To log a particular lamp modify the script around line 18:

Code:

while true do
  reply = getHueLights()
  mylamps = json.decode(reply)
  for _, item in pairs(mylamps) do
    if item.name == 'Cove lighting-cr' then
      log(item)
    end

The reported color temp is 3500K (1000000 / 285). Is it correct?

Have you applied this change? https://forum.logicmachine.net/showthrea...9#pid19499

Hello, again

Yes, the last setting I made was 3500K. I'm using the script you provided for the color temperature.

Do you use the same object for control and status? What is the event script attached to this object? Why do you use string data type instead of 2 byte unsigned?

[NKereshki]

Do you use the same object for control and status? What is the event script attached to this object? Why do you use string data type instead of 2 byte unsigned?

1. I used the same object for control and status. I removed the status part for testing. 
2. I'm applying the script as an event script. 
3. I changed it to 2-byte unsigned. After these changes, the problem remains.

Code:

--Control HUE from TW object (color temperature) (use as event based script)
require('user.hue')
lamp_id = 12
bri = grp.getvalue('32/2/9') -- 0..100%
ct = grp.getvalue('32/4/9') -- 2000K..6500K
setBrightnessCT(lamp_id, bri, ct)

[admin]

You should use separate objects for control and status. Otherwise you might get a loop because color temperature value is not exact due to recalculation.

setBrightnessCT(lamp_id, bri, ct)

Change your Code to 

Code:

--Control HUE from TW object (color temperature) (use as event based script)
require('user.hue')
lamp_id = 12
--bri = grp.getvalue('32/2/9') -- 0..100%
ct = grp.getvalue('32/4/9') -- 2000K..6500K
setBrightnessCT(lamp_id, bri, ct)

Now you controll only the Colortemperature, for brightness use a seperate Event

Hello,

First, I want to thank you for your help. Unfortunately, when I remove the brightness line from the script, the color temperature also stops being controlled. I'm using the script you showed me.

Best regards,
Nayden

Hi Admin,

Sincere thanks for your help. After separating the group address for color temperature control and feedback, everything is working perfectly.

Should I do this separation for the other group objects too: on/off, dimming, and RGB change? I just want to clarify that I also have a physical KNX button through which I turn the lights on/off and dim them. If I separate all controls from feedback, I can't synchronize the KNX button and sometimes I have to press it twice. What occurred to me is if it also "listens" to the feedback group address.

What would you advise, and what do you think is the best practice?

Best regards,
 N. Kereshki

[Daniel]

In general any KNX system is done in a way that there is one object for control and another for status.
