I have an E21-N1 that I am not sure if it is working as expected or not. I have some Basic Rules that set the level and color temp when modes change. That is the only place where I am setting the color temp.
The current state looks good. Color Mode is CT the temp and level are all as currently set by my Basic Rule. If I turn the bulb on from the devices page or the motion rule
80% of the time the bulb will start as blue and then quickly change to the set color. I have tried the Segled Element color plus, basic RGBW and advanced RGBW drivers with the same results.
The logs only show on/off for the device
As this is a new bulb and my first from Sengled, is this normal or do I have something configured wrong or is the bulb bad?
I have tried the Sengled Element color plus, basic RGBW and advanced RGBW drivers with the same results. I am currently running the Sengled Element Color Plus drive which is what it defaulted to when discovered.
If I turn off pre-staging color and level, save, configure. The bulb still does the same thing of turning on blue and then going to the set color. My mode rule that sets the color and level also turns it on rather than just setting the CT and level when pre-staging is disabled.
I am testing this with one of my Sengleds in my office and am not seeing this behavior. I am using Node-RED so it's different than using RM - the commands come in via Maker API. Hopefully it will give you some ideas.
I am setting the color using setColor command and providing all the HSL values. I do not need to turn the bulb on when doing so. Also changing between color and CT works as expected. For CT I just set the temperature and the bulb turns on or changes from color to CT.
I did notice that if the level is different then there seems to be a weird behavior where it uses the previous level and seems to change after the color changes so you get a slight brightness change after the color change itself.
Thanks for testing. I tried several more drivers and sometimes the color will come on as expected but the majority of the time it comes on blue first. I also tried resetting the bulb and re-paring it with no change. I am going to see about getting a replacement.
I'm kinda stumped... unless it's a firmware issue (bulb or HE - I'm on 2.3.0.124) or I maybe have a different device and not realize it? Also I do have transition time set to ASAP not that that should make any difference..
Curious, if you turn the power to the bulb off. Wait a sec, then turn the power to the bulb back on does it behave the same?
Trying with the bulb set to ON
and try with the bulb set to OFF
...before you de-power it.
Just curious if it goes through that same flash of blue.
--------Addendum---------
Looking at mine, always kept in RGB mode, same driver, never get any "pre-flash" color.
Wonder if it is indeed something to indicate the CT mode & temp, as your test showed different for each.
I have this very same blue color issue with one of my bulb. I found out using color temperature bulb and set level (CT) in automation was causing this weird behavior. I changed all my automations to set color (RGB) to avoid this issue.
But interestingly I am not getting this behavior on any of the three sengleds in my office - at least doing it via Maker either Node-RED or by direct browser links.
From the links I posted - I am doing setColor with hsl values and setColorTemperature calls NOT setLevel though...
edit1: I'd really like to figure out what the difference is..
edit2: Just tested with Alexa and my den lights (8 Color+ BR30s + 2 A19s) - no odd color behavior before changes.
edit3: Not that this should make any difference but my Zigbee devices are on a C-5 not a C-7..
I was not cutting power to the bulb before only ZigBee control. If I cut power while on or off, when powering the bulb back on it comes on RGB and then goes to the set CT by visible action. Logs do not show any color-changing event.
So is this a bulb issue, driver issue, hub issue, or just the way it works?
Currently, this defeats the purpose of an RGBW bulb if the W cannot be accessed without hitting the RGB first.
@erktrek that looks like a different bulb
I am on a C7 2.3.0.124
@Navat604 Do you have a map of CT to close to RGB settings?
Okay cool but... both my table lamps in my den are also sengled.. here's the model..
The trick with these are I have them grouped and ZB messaging turned on. Also using Alexa to change the bulb color and everything works as expected. I might try and do the direct maker call and see what happens.
