Proper way to send a http-command to another LAN device?

[Lambik 194]

What is the proper way to send a http-command from the HC2 to another LAN device, like an IP-camera?

The goal is to make a virtual device which can send a http-command to a Panasonic IP-camera. This command will enable or disable the camera's 'privacy mode' mode.

The commands to send is:

Enable privacy modus:

Return: 1 (Enabled)

Return: 0 (Disabled)

Return: -1 (No Func parameter)

Return: -2 (No Kind parameter)

Return: -3 (No Data parameter)

Return: -4 (Invalid Func value or Invalid Kind value, Unsupported feature)

Return: -6 (Error while writing to flash memory)

Return: -7 (Privacy button setting (enable/disable), changed while Privacy Mode was turned on)

Return: -8 (Upper data setting error)

Return: -9 (Administrator ID and password not set)

Return: -11 (Not accessed by administrator)

Thanx in advance!

Hi Lambik,

Not ignoring but there are a few samples on the forum. Proper is a tough question. If your question is which one is Fibaro way, I guess start from a.socha's posts.

Question...

Now I get data in variable CamResponse:

Data:1

How can I filter just the zero, or an other number which is send back, so I can make a if-then construction?

As I mentioned before, I just taking little steps ahead in this programming thing...

(like if CamResponse = "Data:1" then ....)

In LUA you can do this with : string.byte (myString [, position])

string.byte ("Data:1" [, 6])

string.byte ("Data:7" [, 6])

BTW, how can I compare a whole string?

Like:

if CamResponse == "Data:0"

then

........

EDIT: I used another function. The function returns a value with corresponds with ascii-table. Used 'string.sub' instead incombination with 'tonumber'

This what I did:

Global variable:

PrivacyModus_AU with values -1, 0, 1, 2

Main loop:
