Daikin Hardware

[fenx2002]

hello
Yes i have exactly that
but how to get a selector switch after?

[reneklomp]

Hi, I have installed your dzVents script couple of days ago. Thanks for it!
However, I do see some strange behavior... I have tested the script once on Thursday around 14:00 by heating this unit for a while. This nicely shows in the diagram. But strange enough, this usage repeats itself each day after exactly 20 hours later although I haven't touched the airco unit!
Any idea why this is???

The output for the API is:
ret=OK,curr_day_heat=0/0/0/0/0/1/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0,prev_1day_heat=0/0/0/0/0/0/0/0/0/1/0/0/0/0/0/0/0/0/0/0/0/0/0/0,curr_day_cool=0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0,prev_1day_cool=0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0

Hmm, I just looked at the Daikin App and it shows the same - so nothing wrong with the script. Apparently the unit is using some energy for whatever reason every day (each 20 hours)??! I also see that I tested your script on Wednesday apparently. Strange that I don't see it in the Domoticz diagram but will try to test again today.

Strange :
When I compare the energy (and power) values provided by the Dzvents script or by the Daikin app with my Linky electricity counter, I found a factor 2 (?)
Maybe Daikin measure intensity ? 100V in Japan, 220V in UE
To be verify ....

[Jumper3126]

The airco report in a resolution of 0.1kwh. It may therefore vary from a more precise electricity meter. Didn’t come across that it differed with a factor of 2

Hi

please can you help me on how i can control my airco?
i sent you a PM maybe you didn't' see it
it will be very helpful
thanks

[MarsaultP]

Sorry, I don't receive MP
I don't control with Domoticz, only with Daikin app (!)
So, I hope to use Domoticz in a near futur (?) with a virtual thermostat ...
Now, I want just to compare comsuption before and after Daikin install ...

i added in domoticz one split and i have 8 modules but only switches

Could you please create a screenshot?

You should have these devices when adding one unit:

Hello can i get some help please?
Thanks

[yomark]

Go to devices, look for the device, and press the green arrow to the right to add the device. It will then shiw up under switches. It's that simple, and it works like this for all domoticz devices.

[fenx2002]

That's what i did but i don't have the same thing as you
I only have

My version of Domoticz is 4.9700 is it possible that this not working?

Hi
Here are some news.
I did try to upgrade domoticz but it was a mistake as I was on jessie so it fucked up everything.
I got a new sd card and reinstalled everything from scratch so now I am on buster and domoticz 2020.2
I got my database reload so I have everything working.
Now I will do a copy not to loose everything again
The thing is I have the same devices and no selector for the winds of my airco. Did you do something to get the value?
Thanks

This script from "yomark" about Daikin consumption energy
I try to improve and comment just a little bit

Code: Select all

return 
{
--[[
Show hourly energy consumption from Daikin web server
Daikin clock is sync via Internet
Daikin web server send values after *:00
For call at 00:05 -> value to be extract from yesterday array
So, we have a 1 hour decay on the graph. To be exact, it will be necessary to update last value in sql base ....

So which version are you on now?
And which version of the plugin are you using?
What is the Daiking type you are using?
Did you try to remove the device/hardware entirely after you did the upgrade of domiticz and restore?

But in short: You should not have to do anything. In my case(perfera's) , I just added the device, and waited a bit. The swithces should eventually show up automatically(but you must add them to "see" them).

Something else: does a tool like this work: https://github.com/ael-code/daikin-control ?
It should use the same HTTP / GET/POST as this domiticz plugin.

If the above tool does work: you could also do something as described here: https://www.domoticz.com/wiki/Daikin_wifi
(Create your own "switch" and script to control the unit)

[yomark]

Tnx Philippe! Nice work.

This script about a PID controller for Daikin and virtual thermostat with independant room temperature sensor.

Daikin PID controller with an independent temperature sensor and a virtual thermostat

   SETPOINT stemp MUST BE ROUNDED by half degree for command, example :

Tested on a FTXM50N Prefera

Dependencies :
Dummy device -> Thermostat set point
Dummy device -> Switch On/Off
Device temperature -> reference room temperature (NOT internal Daikin temerature)

Optional for tests :
Dummy device -> Custom sensor axis "°C"  (PID_prop)
Dummy device -> Custom sensor axis "°C*mn"  (PID_sum)
Dummy device -> Custom sensor axis "°C/mn"  (PID_diff)

Just a little question : dummy device thermostat set point appear red color on Domoticz screen ... I don't understand the meaning and why (?)

That is because it's not "updated"/"Last Seen" recently(I think in the last hour).

[MarsaultP]

It's strange because the script read the value every 5mn ....

Hi,

I have a setup of 2x ftxa25W wall units and 3x FVXM floor units combined with 2x 2MXM50M9 and 1x RXM50N9 outdoor units.

When I connect the indoor unit to Domoticz, only for the ftxa25w units devices are created. For the floor units nothing happens.

The floor units are more recent. Are they compatible to this plugin? If not, when will they be supported or how do I figure out how to make the plugin compatible?

Thanks!

I have FTXM20 and FTXM25 Perfera's and I can't get a connection. When I select the hardware and input de IP address and click on "Add", I see in the log that a connection error is generated.

In the hardware field I see that I also have to input username and password. I don't see that in the wiki. What do I enter there? The SSID and Key for the wifi dongle? Or username and password for the phone app? Or leave it blank? Whichever, but at the moment with any of these options, I still get no connection.
