As you can see in the video the buttons randomly stop working and don’t send the infrared commands.
This can’t be relied on when used remotely or for automations, if you are not in the same room you don’t know if it worked or not.
Recent purchase, less than 2 weeks old, updated to the latest firmware, there video is taken after a fresh restart.
Hi!
Works like a charm with my AC.
Yes you have to be patient between two button pushes, but I guess it is a safety not to “blur” the IR signal.
Also it has a status return, so you know if it worked.
Because of using HomeKit I don’t have an AC controller in Apple Home. I don’t mind it so much now 
You are not missing much, the integration with Apple Home via Matter also has other issues, it sometimes sends 3 commands instead of one.
For example I have an apple home automation to turn it off when leaving but instead of turning the ac off, it first turns it off, then back on but set to heat, then sets the temp. Other times it just works fine.
Not even sure if that’s the fault of Apple or the M3, but in general I find the whole experience kind of disappointing.
can you resend the video? it seems is pause.
The infrared emitting surface of the M3 is located on the four sides of its body. You can try facing the air conditioner directly, reducing the obstacles between M3 and the air conditioner, and see if it can optimize the control effect.
It’s very obvious in the video when the IR lights are triggered, the problem is that sometimes they are not even when the blue light is blinking.
Is not about the ac unit not receiving the signal, it’s just not being sent.
The vid plays fine btw, maybe it’s your connection, let it to load a bit.
That’s an interesting idea, I’ll try to test it.
Does it do the same thing if you wait a bit more between commands?
On mine I can do it as fast as you actually, but I’m wondering whether there’s some sort of sync between the AC Unit and the M3, as to ack that it received the command.
I have noticed that if I change the AC using the remote, the M3 is catching the order: don’t know if it’s from the remote or from the unit though
Thats shame. I have AC controller from other brand and it works flawless! Hope M3 will get some updates to adress this.
My M-3 hub controls our older Mitsubishi wall mounted split heat pump better than the original manufacture’s thermostat. I suspect much depends on hub placement- distance and line of sight, and the proper selection of the M-3 control app. Perhaps the apps for the different manufacturers differ in the control ability of the various units?
I went thru the IR selection wizard, all buttons work fine. Line of sight is not a problem, it’s just not using the IR blaster sometimes.
I doubt there’s any sync between AC and the M3 unit, it’s just an IR led.
Anyway I can’t seem to reproduce the issue today, buttons work even when pressed very fast.
As I said initially, it appears that it stops working randomly.
