IR blaster for TV

Hello,

Anyone is using IR blaster for control (volume, input and power) the TV?

I have a MCE USB IR blaster, I want configure it to send commands to my TV to volume up/down and power on/off.

I have a lircd.conf with my TV remote keys. I want to map my LE remote volume keys for send IR commands to IR blaster.

Someone could help me?

Best regards.

This is an old Sony TV.

I have the key codes in a lircd.conf. Years ago I have a Debian based HTPC and I could send the correct keys.

Now I want to know how to send thoose codes with commands in a Libreelec Kodi device.

And then assign some remote keys to thoose commands.

Kind regards.
