Intelligent Eye API?

[FezVrasta]

Hi,

thanks for the great document!

I'd like to know if there is a way to get informations from the Intelligent Eye, so I know if there is someone in the room of my Emura.

Thanks!

As far as I know there isn't any api to monitor/manage Intelligent Eye
feature.
If you'll find something about that please share :)

I'll do! I'm still waiting that someone install my AC. After that I'm going to write a Node.js module to manage my AC.

I'll try to sniff the packets with wireshark to see if I find something useful and I'll even decompile the Android apk to see if I can find something :)

Nice!

This is what I did. Official android app do not support special functions like Intelligent Eye. This is why I think there are any api that provides these capabilities. The only way I found to control special functions is through official remote control.

Anyway I would like to keep track of your future progress.

I'll keep you informed here.

I've also been trying to figure out if there is any support in the API for special functions like POWERFUL mode. I did a script to search for API responses on random strings burt with only one unit it would take years to go through the complete search... and the API isn't responsive while searching ... :-(

I think this is another special function not exposed by http api.

The documentation on this repo is not well organized, I hope we can improve it together.
Anyway during my research I found out that on http://daikinsmartdbt.jp/ there was some kind of dakin api documentation. Now the site require restricted access but you can find the source in this repo.

Few days ago I was in your city :)

Do you think it would be possible to read the content of the hardware inside the AC to get maybe some xml or something where are listed the API?

I think that it's possible, but maybe it's a very hard procedure.
