ESPEasy to control air conditioners / heat pumps

[ToniA]

The minimal_IRext_ESP8266_1M and minimal_IRext_ESP8266_4M1M images already include these plugins. I have a PR open to include basic sensor and switch plugins to those images: https://github.com/letscontrolit/ESPEasy/pull/2620

[hryst]

"makes the image more useful, as it has support for temperature/humidity sensors"
Great,

[ToniA]

The PR just got merged, so the latest binary release includes those changes. The images are minimal_IRext_ESP8266_1M and minimal_IRext_ESP8266_4M1M.

Hey all,

I have this a/c unit mounted in my room. I'm not in good relations with the coding, so can someone explain to me if it possible to integrate with it?

Thanks

Can the decoding be done on an ESP8266 via ESPEasy?

Which library does this plugin use?

Greetings,

Assuming the AC unit you are considering has IR control then I understand the library can be used, or you can 'capture' the IR commands from the IR remote that comes with the AC unit. I was lucky and the library contained some codes that work with my Daikin AC unit. My AC controller has been working really well, with ESPEasy as the foundation for that control. My next project is a 'free cooling' controller, which will pump cool air in from the outside on those days when it doesn't make sense to run the AC unit.

Hope this helps.

I am having problems understanding what needs to be done to further decode the "Powerful/Quiet" button on a Panasonic CS-E7PKR. This model uses the same protocol as the Panasonic DKE for the other buttons/functions that have been decoded.

When I press the "Powerful/Quiet" button this is the output I receive with the IR Decoder script:

From generally using the remote control the "Powerful/Quiet" seems to be a special protocol. When the button is pressed it does not change any other setting at the same time. I suspect this means it isn't sending the standard information (Power, Mode, Fan, Temperature, Vertical Vane and Horizontal Vane).

I noticed in the https://github.com/crankyoldgit/IRremot ... anasonic.h

Code: Select all

const uint8_t kPanasonicAcQuietOffset = 0;
const uint8_t kPanasonicAcPowerfulOffset = 5;   // 0b100000
// CKP & RKR models have Powerful and Quiet bits swapped.

Unfortunately I don't fully understand how to use this information.

[ToniA]

Yes, there's a totally separate message for Powerful / Quiet modes. I think it was also a toggle, so you can only switch the state, instead of going into a specific state. I think it defaults to OFF for both if you turn the device first off and then on.

[whatsupskip]

You are correct.

What command(s) would I use to send the "Powerful/Quiet" message?

[swapper]

The library now has 'qlima_1' and 'qlima_2', as different model years of this heatpump have different control messages for the 'frost guard' mode, or 'maintenance' as I call it (heating at ~10 degrees C). If you just use the 'normal' functions, you can also use it as 'carrier_mca'.

Hi!
Found this thread regarding "Qlima" heat pump and its great!
But i cant for the life of me get the special mode "Qlima" work in ESPEasy.

i have understood it as this should work ?
http://IP/control?cmd=heatpumpir,qlima_2,1,6,0,0,0,0

6 for "maintainancemode" or frost protection mode.

ESPeasy gives: Unknown or restricted command!

how do i select the model to "qlima 2" ?


This works fine and turns the heatpump on
http://IP/control?cmd=heatpumpir,carrie ... 2,3,17,1,0

Have been looking in the code
https://github.com/letscontrolit/ESPEas ... pumpIR.ino

im no programmer so this is a longshot and probably totaly wrong, there are no ref to "qlima":

Code: Select all

Bonjour,

je possède une clim Hitachi avec une télécommande RAR-2P2 et le protocole hitachi defini dans heatpumpIR ne correspond pas.
la trame de celle ci comporte 33bytes.

J'ai réussit a décoder les octets qui change et a modifier le fichier hitachi du projet heatpumpIR pour faire des essais.
lorsque que vérifier la trame envoyer via mon esp8266 ou la télécommande cela correspond, mais avec l'unité interne ca ne fonctionne pas

merci pour votre aide si vous avez une idée du problème.

Bonjour,

The general language in this forum is English, can you please translate your message to English?

[step3528]

Hello,

I have a Hitachi air conditioning with a RAR-2P2 remote control and the hitachi protocol defined in heatpumpIR does not match.
the frame of this comprises 33bytes.

I managed to decode the changing bytes and modify the hitachi file of the heatpumpIR project for testing.
when that check the frame send via my esp8266 or the remote control it corresponds, but with the internal unit it does not work

thanks for your help if you have any idea of ​​the problem.

[TD-er]

I'm not really sure if this is the correct place to ask, as it gets very specific very quickly.
We do use this library for the IR handling: https://github.com/crankyoldgit/IRremoteESP8266
If someting is missing or should be extended in the IR decoder, then it must be done there (too) as we frequently update that library in newer builds of ESPEasy.

Maybe there is some protocol disabled in our build, which could/should be enabled to make this work.
But I don't know the inner working of that library very well.

So like I said, not sure if this is the best place to ask. But maybe someone already dealt with this, so it never hurts

Either way, if you find out how to make it work, please let us know so we can either update it in the code, or in the docs.
