IR extender into cabinet

Steefph

Perhaps it is not possible electrically but, would it be an idea to connect a LED to the audio-out on the Homey and place the LED in a cabinet to control devices out of sight? the question of course would be if the internal components can generate the required  frequency <span></span>

Not sure what you are trying to ask, maybe I'm missing something... but what does a LED have to do with an audio port, and what do both of them have to do with IR?

I use an IR extender from Marmitek. You can place the IR receiver in range of Homey and it has a cable and multi 'out' IR units, which you can place inside your cabinet. 
I am not using it in combination with Homey but that should work as well.

There are several IR-transmitters that use the normal 3.5mm connector as connection mechanism. If it would be possible to generate the required frequency by the audio chip, it would be a simple system. Otherwise you will have to use an external device like the one you're using.

Still, why the LED?

even though some IR extenders use a mono/stereo jack as connector, the female connector does need to be wired up for that, homey in this case is not able to send IR frequency signals through the audio jack port.
it is just an easy and cheap way to be able to use 3 wires in a small connector.

just for the people that apparently don't know, an InfraRed LED is the most used way to send IR signals, practically 99% things that send IR use a (or multiple) LED for this

Wouldn't it be better to use a wifi extender instead of a wired one? This would give much more flexibility.

I have build a MQTT IR receiver/sender based on a ESP8266. pressing a remote ir button results in an incoming MQTT message. I can also send any IR command using an outgoing MQTT message. Homey already understands MQTT.

This gateway also supports RF (433Mhz, BLE and other radios)

Weird that people do not know that IR signals are transmitted via an LED in the IR spectrum. What do you think that plastic bubble at the front end of your remote is? 

Any way, Homey is probably not able to generated the frequency required on its audio output. 
Using a wireless system would make it more complicated Why use WiFi if you could use a piece of wire and an IR-LED (like the NEEO Brain has).
