Hello, 

 I am successfully using the MQTT Dash app with Mosquito and Zigbee2MQTT but ran into a problem. I have a xiaomi smart Buton, which publishes "single", "double", "triple", "quadruple", "many", "hold" and "release" states in its toppic in the action section and it's ok ... very nice I intercept this data into the text control and get the appropriate reaction, now I would like to capture what I have on the panel, e.g. double, in ON Receive, and pass the appropriate action to another Topic. for example: 

 if ("xxxx" == "single") 

{

     app.publish ('zigbee / SW2CH / state', '{"state_l2": "ON"}', false, 0); 

}

.....

 and so on ... maybe a Switch and a Case, but I have no idea how to get the information from the text field where I get the script according to $ .action? How to solve this and what variable to read from the text field to get the value of $ .action ... ?? Thank you for your help.

Can you please explain in more details this?:

Hello and thank you for your quick reply. So yes, I have a Zigbee Xiaomi WXKG01LM button that I joined to mosquitto via zigbee2Mqtt and it works,

 I get a message in the

 zigbee / xiaomi topic {"action": "value", "battery": 98, "linkquality": 98, "voltage": 2997} 

 Action value takes the prescription of pressing the value: single, double, triple, quadruple, many, hold and release, 

this data is displayed in the text control using extract from JSON $ .action, 

it causes the string to be changed to action: value. now I want to redirect the appropriate action after receiving a certain value value so that when

 I receive a single post the appropriate message in the zigbee / switch / set topic for example: 

 I press the xiaomi button, I receive action = single and through On Receive I publish the controls in 

/ zigbee / switch / set {"state_l1": "ON"} 

= double publish / zigbee / switch / set {"state_l2": "ON"} 

 = triple I publish / zigbee / switch / set {"state_l1": "ON", "state_l2": "ON"} 

 = quadruple i publish / zigbee / switch / set {"state_l1": "OFF"} 

 and so on ... for mana, release it works fine when the message single, double and td comes in when I have 

ON RECEIVE written in app.publish ('zigbee / switch / set', '{"state_l1": "ON"}', false, 0); 

 but any attempts with if to check the value that came to the text control with action fail if I knew what variable is responsible 

for displaying the value from $ .action in the text field it might be possible to use

 IF (xxxx == single) app. publisch 

 or Switch Case e.g .: Switch"variable" 

case single 

        app.publish ...... 

         break 

case double 

        app.publish ..... 

        break 

.....

 and so on I don't know java script very well I hope I have described it clearly. Thank you for your help

Ahhh. There should be a "Help" button in the script editor window, which leads to a web page.

https://byte1974.github.io/mqttdash/js/text-metric-on-receive.html

So, you can use "event.payload", which contains received raw data, in your case it's JSON string.

You need first convert your data to javascript object and then you can use it.

E.g.:

var obj = JSON.parse(event.payload);

switch(obj.action) {

    // do what you need

}

Of course it's better to wrap json parsing into try ... catch.

Hello

Thanks a lot, now I know how to combine with this case

Greetings.

Hello

Unfortunately, Switch ... case did not work well, as well as Try ... catch,

but the combination If .. else if works very well

Thanks a lot for the guidance, now the Xiaomi Mi button works exactly as I wanted :)
