MagicHome RGB Led with Tasmota, Colorpicker in Sitemap doesnt work

Setup, Configuration and Use Items & Sitemaps

Hey all,

I have a problem with my RGB LED from MagicHome. I flashed it with tasmota and I got it running and it worked well. I can control it from the Paper UI without any problems. But I get sometimes Problems on my sitemap. Sometimes it works and if I change something, rules for example, it doesn’t work correctly anymore.

The Colorpicker doesn’t send the correct values for the hsb color. The slider for the brightness jumps always to the middle after I changed it, but it sends the correct values. If I close the colorpicker window and open it again the colorpicker are always at color white and brightness 50%.

If I save my sitemaps file with a different name then I have in the file it works again, but of course all the other switches not. Do you know maybe more?

It’d probably be helpful to know what those are then. UI use of color picker will sends commands to your Item, those will be visible in your events.log
So will incoming state changes from your device.

I think your problem is probably about transformations needed though; isn’t Tasmota wanting RGB encoded color but openHAB works in HSB encoded color?

Hey Rossko, thanks for the fast reply.

Tasmota works now with HSB color. It also works sometimes and always if I change the name of the sitemap, but then just the colorpicker. For example: The file calls hamburg.sitemap head of the file “sitemap hamburg label=“WG” {” this is correct but the colorpicker doesn’t work, but if I change to “sitemap ham label=“WG” {” the colorpicker works but the rest of course not.

Also, at the beginning the colorpicker works, but if I close the window of the colorpicker and then change just the brightness I get NaN values… If I refresh the tab of my browser the colorpicker shows again the correct values and I can also change the color correct. If I change the brightness the correct values will be send but the slider jumps always to 50% position.

Well, yes, if you break the format the results are unpredictable. This doesn’t help.

Okay, which UI are using with your sitemap and what OH version? That feels like UI is sending brightness only, dimmer style, which corresponds to what you describe you’re doing. Sounds like a UI widget mess up - each UI is different.

I use basic ui and openHAB 2.4.0 Release Build

6

Looks like a UI issue, at least in part - I have no color things but played with a dummy in OH2.4

Starting from Item state NULL, colorpicker works as expected in ClassicUI. Both the color wheel and dimmer slider work. The “up/down” buttons actually function as on-off buttons - I think that is intended but wrong graphics.

Just as a curiousity, Classic UI sends decimal HSB e.g.
Item 'testColor' received command 60,1.0101010101010102,38.8235294117647,100
while Basic UI sends integers.

Moving to BasicUI, the dimmer slider sends the correct info
Item 'testColor' received command 311,70,70
But the graphic slider pings back to the middle, as you saw.

Colorwheel sort of works
Item 'testColor' received command 111,81,50
but always sends brightness 50, part of the slider stuck at 50% bug I guess.

And as you say, the pointer loses its position after widget close/open.
I could reproduce your NaN incidents by close/reopen widget, then click.

I pronounce BasicUI Colorpicker widget 2.4 broken :wink:

It seems odd more folk don’t complain - perhaps it is just some browsers/environments. Mine is Chrome on Win7.
I can’t find any Github issues on this, but it would be interesting if anyone can try this out on a recent 2.5 milestone.

@Lolodomo for comment, known problem?

Hey, thanks for the test. So it is probably no configuration problem. I’m new to OpenHab but not new to programming, so I was a bit worried if it is my wrong config and / or understanding of OpenHab.

So hopefully there will be a fix. I can live with it but would be nice if it works as expected.

8

As a stopgap, I repeat it seems to work fine in ClassicUI

9

Hey, I just tested it and classic ui works here as well but is ofcourse not so nice like the basic ui. Is the a git or something, where I can report the problem?

10

Yes, github. Openhab2 addons would be appropriate I think.

11

Hey,

i didn’t find anything on github regarding this problem… I’m facing the same issue with my colorpicker in BasicUI its sending the correct data and the light changes the color properly, but the slider jumps to 50%. Reloading the site sets the slider to the correct position. Changing the color after reloading lets the slider jump to 50% again.

Im using Openhab 2.5 with basic-ui 2.5

Hey,

go to your tasmota ui -> ip of controller -> settings -> device config -> and choose "Arilux LC01 (37) as your device

now everything should work fine. :slight_smile:
