AC IR code decrypting
-
Gree is the most largest manufacturer of AC devices and Tadiran outdoor unit looks quite a lot like Gree.. at least I'd try that first.
e: Oh. Looks like Carrier also has some relation with Tadiran.

@ToniA can you elaborate?
Yes, on my AC IR decoder sketch I have decoder modules for different heatpumps. Like this:
https://github.com/ToniA/Raw-IR-decoder-for-Arduino/blob/master/MitsubishiElectric.cpp
So, write a new one, and add a call to it into https://github.com/ToniA/Raw-IR-decoder-for-Arduino/blob/master/rawirdecode.ino#L315. First you need to write a condition to recognize the protocol (like, from the first bytes + length etc). Then just start adding functionality, like decoding the temperature, then operating mode etc.

@dpressle could you please also post a picture of the back of your remote control ? I would like to confirm it's the one I quoted above, would be very interesting as it seems this RC/protocol is shared with a loooot of brands and models.
It's a very interesting case for this reason but also because it's using a checksum based on 4 bits words and excluding some of the "data" bits (at least the fan speed), it's the first time I see this. -

@joker_mkd That's a fraction of a VERY interesting document you have posted here
I suppose the other 180 pages are not freely available ? :D -

Thanks, this is great looks like exactly what i need, all the relevant information is there.
I will now write some code to implement this.Thanks.

I suppose the other 180 pages are not freely available ? :D@Nca78 Unfortunately not. This is a part of the document which we use to define IR codes for our product called PebbleAIR . These codes are implemented in the Android and iOS app. It took me a lot of time, money and effort to decode all the different brands and remotes. I often browse the forums and if I see that someone is stuck or in a need, I share remote data from time to time. If you desperately need data for a certain brand od model feel free to PM me, and I might help you.

@joker_mkd I understand, it's very nice from you to share these pages already !
You have a nice product, I love the flashing function I will have to try that just for the fun of it :) -

@joker_mkd product looks great, did you ever thought of making these units smaller (so can be attached on an AC for example) and have some kind of API exposed so any Home Automation can use them? MySensors ZWave Wifi http etc...
@dpressle We are in the process of making an API, because several companies have asked us for this. I was not involved in the process of hardware design, and I agree that the unit could have been made smaller, probably in the next revision.

This is what I have done as a hobby so far: https://www.openhardware.io/view/41/Heatpump-airconditioner-controller
There's no Gree support in the HeatpumpIR library, though.

Hi all,
This post is great. I started writing a similar library myself for Electra AC, I might just add it on top of @ToniA's library.Quick question: can anyone recommend MySensors compatible controller that supports temperature/fan commands ?
The only thing I came across so far is this modification for Vera UI7 thermostat: https://forum.mysensors.org/topic/3606/redesigned-vera-ui7-thermostat-with-heat-cool-setpoint-hvac-state-fan-status-energy-modeThanks!

Hi All,
Library can be found here:
GitHubIt contains a test ino to test the library and a ino to work with mysensors.
If you have any comments and or questions please dont hesitate to ask/comment.Thanks to all of you who helped in this topic and especially to @joker_mkd who donated his gree code document.
