Dahua intercom - API for VTH1550CH?

[Antori91]

I have slightly modified my code (you have to send the channels of the alarm profiles when you arm/disarm remotely the VTH alarm. If not, the alarm channels profiles configuration is reset).
And now it works at 99%. I've this minor issue: when you disarm remotely the VTH, the alarm window of its main screen is immediately updated. Fine ! But when you ARM REMOTELY, the alarm window of its main screen is never updated unless for example you click on this window and leave it by pressing on another window area and then go back to the main menu with the MENU key on its front panel. And now the the alarm window of its screen shows you that the VTH alarm is ARMED and which Alarm profile is armed.

I guess this should'nt be a big deal: You need kinda display refresh after the changes.

There is an updated script from bashis available, get it.
With this you are able to use dahua's internal debugging functions:

You might have success with the command "o open pageMain.". This forces the VTH to jump to main page if you are in any submenu. Could understand that it entails a screen refresh as well. Just give it a try.
With "alarmset" you might even find another way to enable/disable alarms.

It doesn't work with the "o" command (no answer and nothing updated on the VTH screen) ...but...yes it works with the "rh" command for return home page. I have now to implement the DHIP commands sequence in my program to request the VTH to refresh its screen after the alarm changes.

Hello RioGrande75,

Could you please tell me what is the purpose of the two args: SID and magic

query_args = {
"SID":self.SID, # SID will be returned after we called <service>.attach with 'Object ID'
"magic":"0x1234",

 

[riogrande75]

As far as I understood this:
"SID" (explained already after hashtag), it's a kind of a session id you get from the device after attaching a service.
"magic" is part of the the protocol, obviously not important what value it has - it just has to be included.

 

[Antori91]

I've updated the code (available on GitHub) which now includes some security management items:
MQTT: Messages to/from other servers signed using MD5 hash.
VTH: No SSL available, but VTH serial number verified at login and Alarm Disarm requests coming from VTH only accepted:
- if the login time is more than an hour old
- and if the notifyConfigChange SID and request number (self.id) are the same as the configManager.attach SID and request number saved values.

Yesterday, it was the Go Live! Below a picture to try to explain how it works.

Hello partners.
I am looking for a command that allows me to change the brightness of the VTO2000A (day and night they look different).
I was trying this but it is not correct:

http://192.168.1.110/cgi-bin/magicBox.cgi?brightness=40

http://192.168.1.110/cgi-bin/magicBox.cgi?action=brightness40

I think I'm not doing it right
