My Mitsubish AC/Heatpump does not seem to work with my MOES IR UFO-R11

Configuration
1

I have MOES IR Blaster UFO-R11 which I have setup using Z2M.

It seems to be correctly working as I have learned IR codes from my SONY receiver and succesfully been able to control volume/muting on the receiver using the UFO-R11 blaster.

Then I am trying to control my Mitsubishi AC/Heatpump (an older one having the remove control called KM09A). It seems my IR Blaster can learn IR codes from the remote control - but when I then try to send them to the AC nothing happens.

Any idea or support would be great - TIA! :slight_smile:

Here is an example of a learned IR action I have created to turn of the AC.

alias: IR - Heater - Turn off

Hi nikno,

looking at your signal, the analysis shows the following interesting result:

c4d3 6480 + 0000 1000 + 0000 0000 + 0000 0000 + 0000 + c4d3 6480 + 0000 1000 + 0000 0000 + 0000 0000 + 0000 (no short identified)

There are multiple IR / RF protocols, so, I wouldn’t pretend to be able to interpret them all, but at least, I see the same sequence repeated twice in your signal, and the c4d3 6480 hex being sent, followed by long alternate high/low values…

I can’t explain why these high/lows are there, but if c4d3 6480 is the real sequence to be sent, it should be followed by a long silence. Try this - it would make my day if it works :slight_smile: :

Let me know if this works!

Hi Pascal,

Thank you for your efforts! :slight_smile:

“Luckily” I was today at our second home where I have my IR blaster installed so I could try out your suggestions.

Unfortunately I did not have the same luck with the trials. Again I don’t not get any reaction at all from my AC when I send any of the two “Tuya B64” suggestions. They are just ignored. :frowning:

Aw, shame… but looking at the KM09A remote, I realize it looks like a RF (radiofrequency) 433Mhz remote, not an infrared one… while your IR Blaster UFO-R11 seems to be Infrared-only, as the name implies.

I didn’t notice this in the first place, as I am myself using Broadlink, which does both IR and RF, and so does Sensus.

While most IR signals can be easily reproduced, RF devices often rely on a secured Key Exchange (challenge/response), which, to my knowledge, can not be easily reproduced (goal being to prevent your neighbor from remotely playing with your AC or garage door).

How have you acquired the signal for your Mitsubishi AC/Heatpump, was it with your UFO-R11?

Hmm - interesting.

Yes, when I Google on the remote now it seems to be refered to use 433Mhz, which I assume is then RF.

But it seems like the remote also supports IR as I have read the codes by pointing the remote towards the UFO-R11.

So potentially it can be that this remote supports both IR and RF (to be universal) - but then my AC unit (MUZ-GE25VAH-E1) only supports RF.

I checked the user guide and service manual, but could not find any reference to neither RF nor IR…

(I have left the house where I have this one…so cannot at the moment make a hands on test to see if it works without the normal IR pointing…)
