Hi,

I request help from Portugal.

I made a protection with an ESP w / Tasmota + IR Sensor.

to do some functions with the TV control in the room, like turning off the light in the room ... But I am not able to integrate it into NODE-RED.

MQTT receives the code in NODE-RED, but I'm not able to say code x, it does the function y.  
Can you help?

It would be helpful to see the MQTT message that you are trying to utilise.

... add a debug node after the mqtt in node - set to show full msg - and show us the result of a couple of messages so we can see the different types that arrive.

I apologize for my english, google translator.

I think this is what they asked for:

Set the mqtt output to complete msg output.

Great - so from that debug we can see that the (useful) topic is the `testeIR/tele/RESULT` one - and that the reply is a JSON string... and that the really useful bit is the `Data` property within that.  
So first we can change the MQTT node to Output - a parsed JSON object. That would change it from a string into an object... then you need a change node - set to move `msg.payload.Data` to msg.payload - before then feeding into a switch (as you have ) and a debug jsut so you can check it's getting the right sort of data.

Thank you for your help. I understood the plan, but I don't know how to do it. Can it help explained with print or a Node-RED flow?

Change the mqtt node:

Change the switch node, instead of property `msg.payload`, change it to `msg.payload.Data`

I think @bakman2 wants to see what is comming fron the switch, Put a separate debug node on each output of the switch.

I put Debug in the outputs of the Switch, there is no message in Debug, there is simply no message, Debug is empty.

But your object shows: `payload.IrReceived.Data` so that is what you should use in the switch node.

Put another condition in the switch node and use the 'otherwise' option.  
Also, in the switch node are you using 'checking all rules' or 'stopping after first match'?

Use 'stopping after first match' if you aren't trying to make an AND condition with the rules i.e.  
if A and B and C go do something \<== 'checking all rules'  
vrs  
if A go do something1  
if B go do something2  
if C go do something3
