How to set on-level (brightness & temperature) for Osram Tunable White light?

Hello!

Where in deCONZ can I set the on-level (brightness & temperature) for an Osram Tunable White light? (i.e. the values that the light should use when the current comes on wall-mounted standard switch that turns current on/off)

I see several items in “Cluster Info” with “exec” buttons, and also (at the bottom) “Attributes” with a pop-up window “Attributes Info”, where I can “read config” and “write config”. However, I do not know which value to set and if via the “exec” buttons or via that pop-up window. Is this described somewhere?

Thanks for your help! :+1:

Hello, so first a zigbee device need to be powered all the time, we don’t cut the power with switch.

Some device have a setting to set a defaut value on power on, take a look in the cluster “Level Control” for exemple, you can have (if your device support it) some interesting attribute, but for me not the one you want.


        <attribute id="0x4000" name="StartUp Current Level" type="u8" access="rw" required="o"></attribute>

        <attribute id = "0x0011" name="On Level" type="u8" range="0x01,0xff" access="rw" required="o" default="0xff">
          <description>The OnLevel attribute determines the value that the CurrentLevel attribute is set to when the OnOff attribute of an On/Off cluster on the same endpoint is set to On. If the OnLevel attribute is not implemented, or is set to 0xff, it has no effect.</description>

I know they need power, of course. But in case that someone else from the household (:wink:) switches the light off via its standard power switch, at least I want the light to come back on with a state (brightness and temperature) that I define (once and for all time), i.e. I do not want the light to come back on (after power cut/ failure) in a state that it had last.

I have these values, but the last one is greyed out:
Current Level: 254
Remaining Time: 0
Options: 0x00
OnOff Transition Time: 0
On Level: 255
On Transition Time: 0
Off Transition Time: 0
Default Move Rate: 255
Startup Current Level: 0

The light in question comes back on after power failure in a very dimmed state (5%), but I cannot see such a (low) value among the aforementioned parameters. Therefore, I am unsure how to proceed.

BTW, how did you get the parameter in your post on form of code, and where did you get the description from? Also from the deCONZ GUI, or CLI?

It’s copy paste from the xml used by the GUI deconz-rest-plugin/general.xml at master · dresden-elektronik/deconz-rest-plugin · GitHub

I have these values, but the last one is greyed out:

Grayed mean not supported by the device.
Can try this option “Startup Current Level” but from the description it only have impact on on/off.

It is in the “OSRAM specific” cluster. There is a field named “Store Power-on Defaults”. After clicking the “exec” button, the light remembers its state at time of clicking this button and returns to this state after a power failure - just as I wanted it. :blush:

As you pointed me into the right direction, I flag it as “solved”. :+1:

Ha, nice to know, I didn’t think about the specific cluster, as it’s something generic but it mean it’s possible on Osram but probably not on others brands …
