Daikin integration

[course66]

hi robhuls,
of course I tried to run the full script ' python daikin.py' but it never ends. The IP address in dom_ip is 192.168.1.113 which is the IP address of raspberry pi running domoticz (in fact to run domoticz on web browser I go to 192.168.1.113:8080). In my opinion there is a trouble with command urllib2 on domoticz, as I posed here: http://www.domoticz.com/forum/viewtopic.php?f=6&t=8080

Any idea is welcome.

thanks and ciao,
gabriele

Hi,
Another way to pilot HVAC systems (all brands) is to emulate the supplied HVAC remote with IrTrans modules (Wifi or wired ethernet) (Just googelize "IrTrans" to find it)

The first step is to have the IrTans module learn the IR codes. Use the supplied windows SW to do this by putting the module in "learning" mode.
You end up with a list of learned commands in the Irtrans module, such as:

Code: Select all

Now install the IrTrans module in sight of the HVAC you want to pilot, and send an HTTP request to the IrTrans module: It will emit the corresponding Ir code:
F. ex:

Code: Select all

http://192.168.0.18/send.htm?remote=pac_hitachi&command=poweron_21_medium

This can be done from any browser,a linux wget command, or from a Domoticz virtual switch.

I'm doing this for my HVAC systems. Cold or Warm, it's just a matter of "teaching" the corresponding Ir codes to the IrTans modules.

IrTans modules aren't cheap.... but they are cheaper than the WIFI modules sold by the HVAC vendors, and by using IR led repeaters, one module might be enough to control several HVACs. And you can also use the same module to pilot other Ir controlled devices such as an entertainment system or home cinema. It's just a matter of teaching it the right Ir codes.

Enjoy,
Oliviers

Olivers,
it would be better you open another post, cause this especially refers to additional wi-fi module for Daikin splits.

thanks and ciao,

Hello Course66,

The original post says:
"I have this Daikin unit and would like to see this working in Domoticz. Anyone has an idea how to make this work?"
So, I'm just answering to that question by suggesting a solution.... The forum topic doesn't say it is related to "Daikin WIFI" ....

Cheers,
Oliviers

Hi,

I have followed both the instruction for the .sh and Python script < https://www.domoticz.com/wiki/Daikin_wifi > , but I am not sure what is missing. i have used the Python script but nothing is changing (nor controls nor temp). It seems my temperature under 'Utilities' is a fixed at 20,5 degrees C. Also directly on the Pi nothing changes (terminal). I can not control the Daikin either (used the right IDX references to heat/quiet/cool/temp and IPs to Daikin and Domoticz).

What should I be seeing? Or is there any way I can check the LUA scripts?

Thanks in advance! Pi3 latest version Domoticz.

[remb0]

my first daikin airco comes mondaymorning but the scripts from the wiki are already in place.

[jvilly]

I just follow exactly the instructions, but this step goes wrong on my Pi3:

tar xfvz jq-1.4.tar.gz

pi@raspberrypi:~$ tar xfvz jq-1.4.tar.gz

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

Even the command parameter without -z did not work.

So I unzipped the 1.5 version of file on my Mac and placed it in PI folder and continued

make

gives this error

pi@raspberrypi:~/jq-1.5$ make
CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash /home/pi/jq-1.5/config/missing aclocal-1.14 -I config/m4
/home/pi/jq-1.5/config/missing: line 81: aclocal-1.14: command not found
WARNING: 'aclocal-1.14' is missing on your system.

What did I do wrong?

Thanks in advance.

monday I got my controller, but I'm preparing my scripts already.

- is it not possible to got everything in a lua script? so all scripts are editable in the editor?
python or bash are used to give domoticz status updates but all logic in lua?
- I also want to control the airco fully in domoticz with a lua based on humidity, delta's etc. (I have some scripts already)
It would me more flexible then separate the script in bash and lua or python and lua?
I'm I right?

some ideas to improce this great work:
- Same Icons as the app/remote controller.
- usage
- switch selectors (1 button in domoticz for multiple options.

what are you plans with this script?

[remb0]

Here I found more info:

https://github.com/ael-code/daikin-control

[videodrome]

is there any script to import into domoticz the values of the internal temperature of daikin airco?

[remb0]

No, the only way is to extend the current scripts.

But I have done some testing with gizmocuz and is is looking for a permanent method whitout script. native hardware support.
that would be very cool. the only problem is: he must do it in his spare time... so it can take a while.

but it would the best option i think.

[remb0]

first theps are made by gizmocuz. (last beta)

you can now add in hardware. and you see outside, inside en target temperature.

[rjnl]

Very cool that native support is added! So far the temperature readings are working great, however setpoint doesnt work. Looking forward to further development and added fanspeed/mode options so I can replace my existing scripts with this. Any plans to also add humidity control/sensor support for Ururu Sarara models and/or ionizer control for FTXM models? Would love to provide some command input and/or test this, I have both the Urura Sarara and new FTXM models so let me know if I can do anything to help

Where i can find the port of the daikin? In the daikin app there's the mac address, ip add but not the port.

port = 80 (standard http)

Nice indeed. I crashed my SD card so I am rebuilding a new domoticz server (yes, I have a backup, but this is a good time to make a new up-to-date configuration). I had made a lua replacement for my old python implementation that is on the wiki, but never got to updating the wiki. I did inside/outside temp, target temp, on/off and power consumption. The first two now work out-of-the-box and the target temperature is read, but not set when you try to change it. Power consumption is inaccurate (estimated based on cmpfreq, so should not be supported). Thus, the only thing I still have to do in lua is on/off and changing the temperature. This means I can get rid of the script_daikin_time.lua and only need a script_device_daikin.lua!

[robhuls]

I have updated the wiki explaining how to use the daikin integration in the beta version and a few lines of lua scripting so you can switch the daikin on/off and control the temperature.

thanks robhuis!

Thanx, stupid me....

Good job at the moment.
