Xiaomi Gateway Change light color

Setup, Configuration and Use Scripts & Rules

Hi All,

Im attempting to send a command through a rule to change the Xiaomi Gateway LED Color.

I have everything setup and working as it should with the Basic UI setup, I have also created a fake item and setup a rule on status change of this item to turn on the Gateway so I know my rule so far is working.

What is the command to send to change the Gateway Color ?

Any help is appreciated :slight_smile:

Link the color channel to a color item type:

Color Gateway_Color <rgb> { channel="mihome:gateway:34ce008d5a25:color" }

Hi thanks for the reply,
Yes in my items file I have the color setup and this is working I can create a color picker in my sitemap and change the color of the gateway LED.
The thing I cannot do is change the color via a rule …

Why didn’t you say so? :rofl:

YourItem.sendCommand("30,100,100")

Perfect ! Thank you, I was on the right track but had the syntax slightly incorrect.

Hi all,

I’m new in OH world. I have a problem with controling Gateway light in rules so I decided to use this thread.
Here is my issue: I try to change Gateway color to red (Item.sendCommand(“255,0,0”)) in the rule but it always changes to white. Log extract below:

2018-04-02 23:37:56.653 [vent.ItemStateChangedEvent] - MiAirPurifier2_Aqi changed from 30 to 35
2018-04-02 23:37:56.674 [ome.event.ItemCommandEvent] - Item 'XiaomiGateway_Color' received command 255,0,0
2018-04-02 23:37:56.694 [ome.event.ItemCommandEvent] - Item 'XiaomiGateway_Brightness' received command 50
2018-04-02 23:37:56.789 [vent.ItemStateChangedEvent] - XiaomiGateway_Color changed from 0,0,0 to 255,0,0
2018-04-02 23:37:56.795 [vent.ItemStateChangedEvent] - XiaomiGateway_Color changed from 255,0,0 to 0,0,0

and here is my test rule:

rule "test2"
when
    Item MiAirPurifier2_Aqi changed
then
    XiaomiGateway_Color.sendCommand("255,0,0")
    XiaomiGateway_Brightness.sendCommand(50)
end

Please advice something.

Hey,
try

.sendCommand(“0,100,100”)

Im currently using this in a rule to change the LED color to RED when my Garage door is open.

Note: it does not use RGB it uses HSB values for color. A good reference is http://colorizer.org/ and look at the HSV/HSB section to get your color values.

Hi,

Thanks for advice. Good to know this. But this does not change the fact something keeps changing the color to 0,0,0 just after I set my own (see log extract in my previous post).

Do you have any other rules setup that could be changing it back?

No. I just started using OH2. I’m playing around with this. I have few test rules but they are uncommented. I’ve never changed color to 0,0,0.

I’m wondering if Mi Home/Gateway android app can override my values somehow.

EDIT:
crockernr, I get your point now. HSB 0,100,100 is RGB 255,0,0. Will try this leater at home.
Thanks!

EDIT2:
0,100,100 works fine. Thanks a lot!

weird Question, but I took all channel information from my PaperUI and can’t controll my gateway.
Mi Home app works fine. Do I miss something?

The same for me, have you found a solution ?
