Daikin Hardware

[spiderjn]

hi,

i discover a standard hardware controler Daikin (code by gizmocuz), i try it on my first wifi and it's worked by i can't change value or acces to all command.
I discovered code letting me think that the development was made under windows (and debug).
I try to add a second hardware but nothing seems to be add to my config (Sensor,..)

there are other posts on the subject, but I would like that kind of device can be managed as standard by my installation.

how i can help to complete this interesting feature ?

Best regards

Hi All

i've made some modification to existing module, Start/Stop, Set Thermostat, Led On/Off.

Now i want add a multivalue switch, but i can't find information or sample to do that in source.

Any information for help me ?

Best regards

Have fun

[remb0]

great! will test it soon.

[spiderjn]

Hi
do you have test it from beta ?
Best regards

[remb0]

Yes and it works great! I will test it better tomorrow. and report it when i found something. but for now: great work!!

[spiderjn]

Hi Remb0,

i search how automatize temerature set point, i can change it on web interface, but how do that with "Scénario" ?

i lost something in module ?

Best regards

This plugin/module for domoticz works very well, the only thing Im missing is, when I add the 'Mode', how am i then able to have this say "Heat", "Cool", "auto" and so on? What do I need to change for that to work?

Update:
For those wanting to know, i changed the Airco Mode to Selector and then manually added these to each button:

Code: Select all

- Off : http://192.168.1.19/aircon/set_control_info?pow=0&mode=3&stemp=19&shum=0&f_rate=A&f_dir=0
- Cool : http://192.168.1.19/aircon/set_control_info?pow=1&mode=3&stemp=18&shum=0&f_rate=A&f_dir=0
- Heat : http://192.168.1.19/aircon/set_control_info?pow=1&mode=4&stemp=21&shum=0&f_rate=A&f_dir=0
- Auto : http://192.168.1.19/aircon/set_control_info?pow=1&mode=0&stemp=19&shum=0&f_rate=A&f_dir=0

The 192.168.1.19 is the IP of my Daikin Wifi module.

Bit of an old post, so hope it is still read.

Has anyone tried to control the additional features such as powerful via http post? This feature is available via the app so it should be possible I guess.

I'm able to control the standard options using

Code: Select all

http://192.168.1.76/aircon/set_control_info?pow=1&mode=4&stemp=22&shum=0&f_rate=B&f_dir=0

When I put the airco in power mode and ask get_control_info it shows adv=2, which it doesn't with the powermode off.

Code: Select all

http://192.168.1.76/aircon/set_control_info?pow=1&mode=4&stemp=22&shum=0&f_rate=B&f_dir=0&adv=2

This command doesnt put it in the correct mode unfortunately

[ubfssF]

I am using a blocky "program" to control my new Daikin airco (see my other post in a thread the Heating and cooling list), but in my experience switching mode (from Cool to Heat etc) does not work reliable. It sometimes works, but often it does not.
I see in the log: 2020-05-13 11:56:48.670 Error: Daikin: Error connecting to: 192.168.1.76
Strangely changing the setpoint and putting it on and off seems to work every time.

Is it never working for you?

[Jumper3126]

Hi,

Switching to cool isn't an issue. I want to use the powermode, in which it blows very cold air for 15 minutes. This feature isn't standard with the daikin hardware in domoticz, but you can select it in the app. I think it should also be possible when giving the http command, but havent found out how.

I use powermode in my Domoticz; created a selector switch for it, in my setup with the name "Daikin Special Mode". In this switch I have three buttons: off, Power Mode and Economic Mode.

In my setup I have a LUA script controlling the Daikin, I have added some stuff for the Powerfunctions. The snippet of the code is:

Code: Select all

if (devicechanged['Daikin Special Mode']) then
    print ("Daikin Special Mode Script started")
     if (otherdevices['Daikin Special Mode'] == 'Off') then
            spmode = '0'
            sPowermodegezet = tonumber(uservariables['Daikin_Power_Mode'])
		    if (sPowermodegezet~=0) then
		        spmodekind = tonumber(uservariables['Daikin_Power_Mode'])
			    print ("Powermode was " ..spmodekind)
			end

        elseif (otherdevices['Daikin Special Mode'] == 'Economic Mode') then
            spmode = '1'
            spmodekind = '2'
			commandArray['Variable:Daikin_Power_Mode'] = tostring(2)
        elseif (otherdevices['Daikin Special Mode'] == 'Power Mode') then
            spmode = '1'
            spmodekind = '1'
            commandArray['Variable:Daikin_Power_Mode'] = tostring(1)
    end
    cmd = 'curl "http://' .. daikin_ip .. '/aircon/set_special_mode?set_spmode='..spmode..'&spmode_kind='..spmodekind..'"'
    print ("command: "..cmd)
    os.execute(cmd)
end

Keep in mind that this is not the whole script only the part with the Modes. Basically you don't need to have the code; you can use the variables SPmode and SPModekind to setup these buttons! Try it using a http command

[Jumper3126]

Great, that is exactly what I needed! Thanks

How did you find this out? I didn't come across this somewhere

Is it possible for you to share the whole Lua Daikin script? That would a great asset for me and other users

[CronoS]

Ofcourse; here is the lua I am using. I have setup the following buttons:
Daikin Power: on/off
Daikin Mode (selector switch): auto, drogen, koelen, verwarmen, ventilator
Daikin Special mode (selector switch): Off, Powermode and Economic mode
Daikin ventilator snelheid (selector switch): Auto, silent, L1, L2, L3, L4, L5
Daikin Wind (selector switch): off, Roteren
Daikin Zet temperatuur: set temp value
Daikin Led Indicator: on - off

Basically these buttons also comes with the hardware setup in Domoticz, so keep in mind to use the rigth button accordingly. The Daikin Special mode button is not something that comes with the plugin .. Also I have more buttons for my airco with blockys, but that is more to automate the airco, so maybe you need more in you're automation needs besides these.. but these are the basics for me.
My Daikin is also only able to rotate in one direction, so I only use off and rotate. Normally in a standard domoticz setup, this switch has more values but these do not apply on my Airco.

The script: change the IP adress of the Daikin Wifi

Code: Select all

commandArray = {}
daikin_ip = 'IPADRESS'

        elseif (otherdevices['Daikin Ventilatorsnelheid'] == 'l5') then
            f_rate = '7'
        end
        f_dir = '0'
        if (otherdevices['Daikin Wind'] == 'Uit') then
            f_dir = '0'
        end
        if (otherdevices['Daikin Wind'] == 'Roteren') then

        print ("command: "..cmd)
        os.execute(cmd)
    end
end

if (devicechanged['Daikin Special Mode']) then

			    print ("Powermode was " ..spmodekind)

        elseif (otherdevices['Daikin Special Mode'] == 'Economic Mode') then
            spmode = '1'
            spmodekind = '2'
			commandArray['Variable:Daikin_Power_Mode'] = tostring(2)
        elseif (otherdevices['Daikin Special Mode'] == 'Power Mode') then
            spmode = '1'
            spmodekind = '1'

    print ("command: "..cmd)
    os.execute(cmd)
end
return commandArray

In the Powermode part of the Script I also use a Variable "Daikin_Power_mode" where I change that to 1. 1 means On, 0 means off. When the airco is switched off I also have a blocky to reset the Powermode switch to off and change that variable to 0, otherwise that Special Mode selecter will stay at a enabled value when the airco is off. Maybe you want to set up this differently, but for me that worked OK. In the normal way the daikin works, the powermode is switched off after 20 minutes I thought.
Also my airco doesn't have a humidity sensor, so I cannot set that value... maybe you have one, then you can expand you're script maybe.

I use it for quite some time now, it works OK...

[ubfssF]

Thanks!!! As I am Dutch as well, there is not a lot that needs to be changed in the script

Edit: after adding the LUA script (device-triggered), switching the special mode works fine!

However, the log file shows this error for this line of code when I tried to change the mode:

Code: Select all

2020-05-20 13:01:29.079 Status: User: Admin initiated a switch command (474/Daikin Mode/Set Level)
2020-05-20 13:01:29.101 Status: LUA: Daikin script started
2020-05-20 13:01:29.102 Error: EventSystem: in Daikin airco 2: [string "commandArray = {}..."]:44: attempt to concatenate a nil value (global 'stemp')

Row 44 is:

Code: Select all

cmd = 'curl "http://' .. daikin_ip .. '/aircon/set_control_info?pow='..pow..'&mode='..mode..'&stemp='..stemp..'&shum=0&f_rate='..f_rate..'&f_dir='..f_dir..'"'

The airco isn't reacting also to the command to switch mode.
The same error occurs when I try to change the modes for Daikin Wind and Daikin Ventilatorsnelheid.
The Daikin Power switch isn't working as well, but it doesn't initiate an error.

@CronoS: can you give me a hint on what the cause of these errors are?

What I have done so far:
- I have added dummy devices als switch with a choice (Keuzeschakelaar) or just switches. For Daikin Zet temperatuur I have used the setpoint variables
- for each of dummy devices I have set the different states that are possible, as used in the script. For example: for Daikin Mode these are Verwarmen, Koelen, Auto, Drogen, Ventilator. For Daikin Wind I had used Uit and Roteren, which didn't work. I've used Stopped, Vert, Hor and both, and changed the code, but that doesn't solve it as well. Changed code:

Code: Select all

        if (otherdevices['Daikin Wind'] == 'Stopped') then
            f_dir = '0'
        end
        if (otherdevices['Daikin Wind'] == 'Vert') then
            f_dir = '1'
        end
        if (otherdevices['Daikin Wind'] == 'Hor') then
            f_dir = '2'
        end
        if (otherdevices['Daikin Wind'] == 'Both') then
            f_dir = '3'
        end

- I have added an integer user variable called Daikin_Power_Mode

[ubfssF]

Fixed it. It was a typo: I had named "Daikin Zet Temperatuur" wrongly to "Daikin Zet temperatuur"

[CronoS]

Awesome! Glad it worked, but indeed everything is case sensitive
A mistype by me But great it works out OK

[Jumper3126]

I got my daikin airco script running quite nicely now, allowing me to turn on/off and switch mode based on time and conditions. But I also want to be able to control the airco via the app.

To do so, I read out the current settings according domoticz (via the daikin hardware), change only settings if there is a reason to (like time) and then send those settings back to the airco via:

Code: Select all

domoticz.openURL('http://ip adress/aircon/set_control_info?pow='..pow..'&mode='..mode..'&stemp='..stemp..'&shum=0&f_rate='..f_rate..'&f_dir='..f_dir)

This works if I turn off the airco with the domoticz airco power switch, but not via the app. Further inspection showed that not all daikin domoticz devices are frequently updated. The temperatures, wind setting, ventilation and LED are updated every 5 minutes, but the mode, power and setpoint are not. This explains why my script doesnt run as intended.

Do others have this as well?
What is the reason that not all devices are frequently updated?
Is there a solution (apart from asking for an update of those parameters via a command)?

[Jumper3126]

FYI this is the complete script. Note that it is still very drafty. The airco is installed in a serre with a lot of plants for which I need to control temp and humidity

Code: Select all

	active = true,

	},

            ForcedOff= {initial = 0 }, -- 1 if airco was forced off because of door
