hello this is my first post, I hope you can understand me and help me. I want to control the leds of a partner through mqtt, this previously I had already achieved but this time I want to do it through an infrared sensor controlled by a control of the same type, I have tried a thousand ways but I c…

First use a Switch node to send the message down three different paths, one for each sensor value. Use debug nodes to check that is working. When it is working then add a function node in each one of those three outputs containing // Set these to the correct values for the led const on_off_values …

Hello and welcome to the forum. You'll need to provide more information/details as I'm having a problem visualising your set-up. For a start you could tell us the hardware you are using. For example, have you got a Raspberry Pi acting as a broker and what hardware is your 'partner'? You also men…

I'm really sorry Kevin but I'm not going to be of any further help as I've not used the serial comms link or infrared in this way. I'm sure someone else from the forum will jump-in and offer some guidance/help.

Thank you very much for your time sir dave and I appreciate your intention, and I hope if anyone can help me.

I can't send the infrared control data to my partner to turn on his leds.

[image] KevinGallardo619: I can't send the infrared control data to my partner Which bit of that isn't working? Getting the infrared sensor into node-red? Getting it from node-red to MQTT? Your partner picking it up from node-red?

I can get the sensor data to node-red, what I can no longer do is to use that data to get the leds to turn on.

I thought you were sending it to MQTT after you get it into node-red.

yes, I put it in mqtt to send it to my partner or better explained I use the sensor data to pass them to a function node which is the part that I don't get to send it through a mqtt and thus interact with my partner's leds. yes, I put it in mqtt to send it to my partner or better explained I use …

So is the problem that you have the sensor data, but you don't know how to reformat it the right message to send via MQTT? If that is the question then show us what the sensor data looks like in a debug node, and tell us what you need to send to MQTT.
