MagicHome with Tasmota and OpenHab2

[imhofa (Andreas Imhof)]

Hi @lxfrdl,

you have to install MQTT binding to get the publish command…

So just install MQTT binding via PaperUI and configure it in service/mqtt.cfg

Hey @imhofa,

what a fast support :).

I already installed it an configured it under services/mqtt.cfg.
I found trough research that I need

import java.awt.Color

before the rule to Support Color.
Maybe it it something similar?
Anyways thanks for your reply!

I have the following imports at the beginning of the rule file:

import org.openhab.core.library.types.HSBType
import java.awt.Color

Do you get some information in the logs about mqtt at startup?
If the binding is installed you should have the publish command…
So just restart openhab and see what the logs are saying about mqtt binding…

Andreas

edit: AND you need the MQTT Action Binding as well…

@imhofa

edit: AND you need the MQTT Action Binding as well…

This was the missing piece :). After I installed the Action it works like a charm.

import org.openhab.core.library.types.HSBType

resultet for me in the error Configuration model 'alex_rgb_beleuchtung.rules' is either empty or cannot be parsed correctly!

To sum up after installing MQTT Action and MQTT Binding the following rule

import java.awt.Color

rule "Set RGB value Alex RGB"
  when
    Item Alex_RgbStrip_Color changed
  then
    var HSBType hsb = Alex_RgbStrip_Color.state as HSBType
    var Color color = Color::getHSBColor(hsb.hue.floatValue / 360, hsb.saturation.floatValue / 100, hsb.brightness.floatValue / 100)
    var String rgb = String::format("%1$02x%2$02x%3$02x", color.red, color.blue, color.green)
    publish("broker", "cmnd/alexrgb1/color", rgb)
    Alex_RgbStrip_RGB.postUpdate(rgb)
  end

works perfectly.

@imhofa Thank you so much!

[imhofa (Andreas Imhof)]

Sorry about the late information about MQTT Action. Most times you install a setup but can’t remember every single step…

Glad that it’s working now…

@lxfrdl

ar HSBType hsb = Alex_RgbStrip_Color.state as HSBType
var Color color = Color::getHSBColor(hsb.hue.floatValue / 360, hsb.saturation.floatValue / 100, hsb.brightness.floatValue / 100)
var String rgb = String::format(“%1$02x%2$02x%3$02x”, color.red, color.blue, color.green)
publish(“broker”, “cmnd/alexrgb1/color”, rgb)
Alex_RgbStrip_RGB.postUpdate(rgb)

Thanks it works for me also. But one issue encounters. I’ve connected a WS2812 to a Wemos Mini. It’s running well, also color changing works with the rule above. But if I select a scheme (Webconsole command e.g. “scheme 8” ) Than i get the following error in openhab.log:
018-03-21 14:29:51.434 [ERROR] [.mqtt.internal.MqttMessageSubscriber] - Error processing MQTT message.

Blockquote

I think the problem is, that the return value of the mqtt broker is different, depending on what action is started:
stat/sonoffWemosMini/RESULT {“POWER”:“ON”,“Dimmer”:100,“Color”:“00FF00”}
stat/sonoffWemosMini/RESULT {“Scheme”:2}

I think a workaround would be to grab complete Result String and split it up into separate mqtt items manually…

Anybody an idea to proceed?

[imhofa (Andreas Imhof)]

The problem is that Tasmota answers with different payload within RESULT as you showed.
If you change the dimmer value then the JSON returns just the value for “Dimmer”, if you change the color the answer is just the “Color”-value.

I can live with the error messages in this case…

The only solution I see is getting a Proxy item with the JSON return and split this within a rule. With this solution it is possible to check the payload and update the corresponding item…

For me: too much work…

Hi,

wrote a mail that “greps” out the JSON Result, so no Logging occurs any longer:

rule “Wemos Mini 1 LED Result Topic”
when
Item i_mqtt_sonoffWemosMini_1_Result changed
then

        if (i_mqtt_sonoffWemosMini_1_Result.state.toString.contains("Speed") ) {
            val speed = transform("JSONPATH", "$.Speed", i_mqtt_sonoffWemosMini_1_Result.state.toString)
            i_mqtt_sonoffWemosMini_1_Speed.postUpdate(speed)
        }

        if (i_mqtt_sonoffWemosMini_1_Result.state.toString.contains("POWER") ) {
            val power = transform("JSONPATH", "$.POWER", i_mqtt_sonoffWemosMini_1_Result.state.toString)
            i_mqtt_sonoffWemosMini_1_Power.postUpdate(power)
        }
        
        if (i_mqtt_sonoffWemosMini_1_Result.state.toString.contains("Color") ) {

            i_mqtt_sonoffWemosMini_1_Power.postUpdate(power)

            val dimmer = transform("JSONPATH", "$.Dimmer", i_mqtt_sonoffWemosMini_1_Result.state.toString)
            i_mqtt_sonoffWemosMini_1_Dimmer.postUpdate(dimmer)
        }

        if (i_mqtt_sonoffWemosMini_1_Result.state.toString.contains("Fade") ) {
            val fade = transform("JSONPATH", "$.Fade", i_mqtt_sonoffWemosMini_1_Result.state.toString)
            i_mqtt_sonoffWemosMini_1_Fade.postUpdate(fade)
        }

        if (i_mqtt_sonoffWemosMini_1_Result.state.toString.contains("Pixels") ) {
            val pixels = transform("JSONPATH", "$.Pixels", i_mqtt_sonoffWemosMini_1_Result.state.toString)
            i_mqtt_sonoffWemosMini_1_Pixels.postUpdate(pixels)
        }    

         if (i_mqtt_sonoffWemosMini_1_Result.state.toString.contains("Scheme") ) {
            val scheme = transform("JSONPATH", "$.Scheme", i_mqtt_sonoffWemosMini_1_Result.state.toString)
            i_mqtt_sonoffWemosMini_1_Schema.postUpdate(scheme)
        }         

end

Here are the items:

Of course MQTT Topics must fit for you environment…

Are there anyone here who use this kind of MagicHome (copy maybe?) with Tasmota and OpenHab:
link

If yes, does it requires flashing Tasmota? Or it can be used without modifying the firmware? Is this thing reliable?

Thanks

[wars (Ward)]

I just started using this controller with OpenHAB this week. You can use the wifi LED binding, is working fijne.
https://docs.openhab.org/addons/bindings/wifiled/readme.html

[rkrisi (Kristof Rado)]

Thanks!
Yeah I saw this binding before, but I was not sure that Tasmota is needed for this or not.
Do you use some modified firmware or you use the original firmware on this controller?

[wars (Ward)]

Nope, no other firmware. So it’s realy simple. Discovery is also working if needed.

[rkrisi (Kristof Rado)]

Thanks for your help!

[Nico111 (Nico F.)]

Is there another way to send HSB Values to the Arilux (AL-C01) Controller without reflashing them?

[ut1545 (Antonio C)]

Hello Nico111,
I guess that you are talking about AL-SL 01. If so, I’m using it with WIFI Led bind and original firmware and works perfectly. As I know, you can send HSB values. I have configured " LD382A" as protocol.

[Nico111 (Nico F.)]

@ut1545

guess that you are talking about AL-SL 01

Nope I’m talking about this one.

[ut1545 (Antonio C)]

Seams to be the same that I’m using. I have found several model name for the same device.

[Nico111 (Nico F.)]

Yeah it’s the same, They produce them and label different names on it.
Basically just a ESP8266

[jacobkuriakose]

Follows this you can do it with magichome without Tasmota.

[SOLVED] WiFI LED Binding - LD741

Hi Guys, today i got my new MAGIC HOME LED Controller ( 9 USD ) and i want to use it in OpenHAB. i think this is an LD741 Device i already installed the WIFI LED Binding in Paper UI but now i am a little bit confused how to set up the device (item/sitemap) - The Manual says: Usually, there is no need to define your WiFi LED controllers via configuration files. So how do i set up my led strip to work in openhab ? ( items/sitemap ) Thank you! PS: This device should work…

[Atomius (Meik)]

Hi Andreas,

thanks for sharing. Could you also add your sitemap configuration so I can get it to work?
