Do you found any solution on this Daikin VRV integration?

I am looking for this too.

Thanks.

You need to figure out the protocol and then I can try to help you build an integration.

Check the whirlpool forum and see if someone managed to figure out the protocol.

Hi fredrike,

From what I could find from Google, this Daikin system use ModBus protocol with DIII-NET connection.

Reference Documents:

There is a modbus component in home-assistant but I do not have any experience with it. Do you have an app or web page you can control your devices via?

Hi fredrike!
I appreciate your support for giving your helping hand.
Modbus dta116a51 connected via pi (from daikin ~ webserver). I control my devices via local webserver (for my case I control via daikin PI’s ip address).
I have demo site: http://svmdemo.ddns.net/
Thank a lot

I need to see the source code for your webpage to be able to help…

Ok. How do I get source code from my webpage??? Or do you have tools to download all source from my daikin local webpage? Sorry!!! I’m noob

It is web page to control.

The demo website is the same as per provided by @braverynew.

Thanks.

Now demo webpage is running. You can see source code.

Any updates on this?

Thanks.
