I have 2 recorded IR signal for Power on/Power off as text files . Mosquitto Broker online through binding and Generic Mqtt thing online in OH3. Dont know how to link the signal files to the topic
Any help is very appreciated !

You can link an item to the command channel of the broadlink thing and use a .map file which you link in the profile settings.
Then when, i.e. putting the item to “ON” it will use the map file to convert that to the IR signal and send it with the command channel to the broadlink device.

Example below from my config:

Thing and Channel:

Item config:


Map file:


You could also send those commands direct to the command channel via one item, I prefer to split it though.

  • Where do you put the file ? is it in openhab/conf/maps or /conf/items
  • The Rule picture you have “Edit script” at the top right, which one is it ?

I’m kinda struggling quite a bit. This is what i did, is it correct ? I dont know Javascript so if you can example the script part for my case, it would help a lot ! type files for transformation use belong in /conf/transform, which should already exist with a couple of samples.

Hi @Tu_n_Long

Were you able to make it work?

The tutorials I’m finding are pre-rm4 versions of broadlink and I have a Broadlink RM4 Mini which I’m hoping to integrate with OH3. Did you use this:

If you have a link to the guide please let me know, thanks.

I have an RM4C Mini which I integrate with openHAB via the same broadlink-mqtt as mentioned by the OP:

Perhaps this helps, as it’s a post-RM4 tutorial…
