Zigbee2Mqtt + Nous P3Z (TS0505B) RGB between Color and Temp/Brightness modes

,
1

I own a few RGB lights including some NOUS P3Z.
Those work fine in Z2M and almost fine in OH so I think I have an issue with my transforms.

In my rules, I will sometimes use RGB changes such as:

Kitchen_Table_RGB__Color.send(new HSBType("25,64,41"))

and sometimes use temp+brightness such as:

Kitchen_Table_RGB__Temp.send(new PercentType(80))
Kitchen_Table_RGB__Brightness.send(new PercentType(80))

From what I see, using __Color always work fine but if I change the color and then use temp+brightness, the temp goes crazy. Ie, I am setting the temp to 100% and it will jump back “on its own” down to 4%.

Could someone share what they are using if that works ?

Here is how I defined it:

Thing mqtt:topic:_MosquittoBroker:p3z_zb030 "Z2M - ZB030 - E27 RGB Kitchen table" (mqtt:broker:_MosquittoBroker) @ "Kitchen" {
    Channels:
        Type switch : state "State" [
            stateTopic="zigbee2mqtt/ZB030/state",
            commandTopic="zigbee2mqtt/ZB030/set/state"]

        Type color : color "Color" [
            stateTopic="zigbee2mqtt/ZB030/color",
            commandTopic="zigbee2mqtt/ZB030/set",
            colorMode="XYY",
            transformationPattern="JS:z2m_hal550_color_in.js",
            transformationPatternOut="JS:z2m_hal550_color_out.js"]

        Type dimmer : brightness "Brightness" [
            stateTopic="zigbee2mqtt/ZB030/brightness",
            commandTopic="zigbee2mqtt/ZB030/set/brightness",
            min=0, max=255 ]

        Type dimmer : temp "Temp" [
            stateTopic="zigbee2mqtt/ZB030/color_temp",
            commandTopic="zigbee2mqtt/ZB030/set/color_temp",
            min=153, max=500 ]

        Type number : linkquality "Link Quality" [
            stateTopic="zigbee2mqtt/ZB030/linkquality"]
}

Don’t mind my file naming that is no longer matching.

with z2m_hal550_color_in.js:

(function (x) {
    var o = JSON.parse(x);

    // The brightness value is received as integer 1-254 but needed as percentage 0.100
    var brightness = Math.round(o.brightness / 254 * 100);
    return o.color.x + ',' + o.color.y + ',' + brightness
})(input)

z2m_hal550_color_out.js:

(
    function (x) {
        var [x, y, brightness] = x.split(',');
        x = parseFloat(x);
        y = parseFloat(y);

        // The brightness value is received as percentage but needed as integer 1-254
        brightness = brightness * 2.54;

        var payload = {
            color: {
                x,
                y
            },
            brightness
        };

        return JSON.stringify(payload);
    }
)(input)
