Daikin VRV HVAC HTTP virtual device control

[Spenden 0]

I need to control a Daikin VRV multi-split HVAC system which has their intelligent touch controller with the HTTP interface option installed. To control each individual indoor unit I need to send an HTTP POST.

Below is an example of the information the controller is expecting the HTTP POST to contain...

Here is an example to get A/C "1:1-02" current status.

HTTP Request

POST /cmd/ HTTP/1.1 ¥r¥n

Content-Length: 32¥r¥n
Content-Type: application/octet-stream¥r¥n

¥r¥n
20 000000 {Command Size;32}
74 110100 {Command ID;70004}
00 000000 {Reserved 1}
00 000000 {Reserved 2}
04 {A/C Address to get status; 1:1-00 to 1:1-07 (1:1-02 is enable)} -------
00 {A/C Address to get status; 1:1-08 to 1:1-15}
00 {A/C Address to get status; 1:2-00 to 1:2-07}
00 {A/C Address to get status; 1:2-08 to 1:2-15}
00 {A/C Address to get status; 1:3-00 to 1:3-07}
00 {A/C Address to get status; 1:3-08 to 1:3-15}
00 {A/C Address to get status; 1:4-00 to 1:4-07}
00 {A/C Address to get status; 1:4-08 to 1:4-15} Request Command (hexadecimal)
00 {A/C Address to get status; 2:1-00 to 2:1-07}
00 {A/C Address to get status; 2:1-08 to 2:1-15}
00 {A/C Address to get status; 2:2-00 to 2:2-07}
00 {A/C Address to get status; 2:2-08 to 2:2-15}
00 {A/C Address to get status; 2:3-00 to 2:3-07}
00 {A/C Address to get status; 2:3-08 to 2:3-15}
00 {A/C Address to get status; 2:4-00 to 2:4-07}
00 {A/C Address to get status; 2:4-08 to 2:4-15} ---------

I am trying to create a virtual device for each indoor unit (room) and have looked at a lot of posts and tutorials and can’t find anything similar to point me in the right direction, so any ideas how to get this up and running appreciated...

Did you find out how to get it working?  I'm about to start down the same path. What was the part number of the Daikin HTTP interface?
