Dahua IPC to MQTT App

i found this on the pycurl github:

The line of code that throws Could not run curl-config: [Errno 2] No such file or directory” when installing pycurl on Linux, should inform the user as to remedy - a pre-requisite, rather than leaving them to test their google skills. A page online is the remedy, and it could have sections like the following for Raspbian GNU/Linux 8 (jessie):

sudo apt-get install libssl-dev libcurl4-openssl-dev python-dev

i guess they didnt succeed in preventing the google hunt.
so the search goes on to the right packages.

libssl-dev
libcurl4-openssl-dev

could do the trick as system packages.

and i did some searching on egg-info errors, and it seems thats a part from the python package setuptools

so its probably to much installing, but could do the trick (remove what throws an error)

libcurl4-gnutls-dev: /usr/bin/curl-config
libcurl4-nss-dev: /usr/bin/curl-config
**libcurl4-openssl-dev: /usr/bin/curl-config**

I guess the last one is missing.

Yep, didn’t like that.

oke, try again without libssl-dev

Had to remove that and libcurl4-openssl-dev. Sadly, same errors. I’m sure there will be some combo that works? :roll_eyes:

Do you have access to shell via SSH or directly?

I use this python script to monitor Dahua IVS events and it works great for me:

i think the only thing that is missing is a package that includes curl-config and can be installed on hassio.
the problem is to find that package.

these packages seem to contain that:

* libcurl4-gnutls-dev
* libcurl4-nss-dev
* libcurl4-openssl-dev

libflickcurl-dev
curl-dev

its very well possible that curl-dev now works, now that we found out the right pip and the need for python-dev

@algirdasc there is no use trying trough SSH.
the package needs to be installed inside the docker

I had to enter my appdaemon docker container and install packages manually.
apk add curl-dev python3-dev libressl-dev
After that I just created requirements.txt with pycurl in it. But I’m not 100% sure if thats the correct way on HassOS.

if i have understand apk correct then you dont install with apk add, but you make it available.
the install is done by the requirements file.
but i doubt that they have even apk available in hassio/hassOS/addons.

the problem is that not everything is available for such a slimmed down OS.

just an idea (dont know if its possible and if its worth it)
but you use pycurl for the connection, dont you?
isnt the same thing possible with something like requests?

Shall I try adding those?

curl-dev was already tried as python package, but maybe its a system package
i would try on or the other and remove what doesnt work.

Making some progress. Came up with a ‘gcc’ error so I added that and we move forward but not quite there yet.

Getting real close!!

Seems there is something in the code that might require customisation??

class DahuaMQTT(hass.Hass):

	proc = None
	cameras = []
	curl_multiobj = pycurl.CurlMulti()
	num_curlobj = 0
	kill_thread = False

	def initialize(self):

		for camera in self.args["cameras"]:
			dahuacam = DahuaCamera(self, camera)
			self.cameras.append(dahuacam)
			url = URL_TEMPLATE.format(**camera)

			curlobj = pycurl.Curl()
			dahuacam.curlobj = curlobj

			curlobj.setopt(pycurl.URL, url)
			curlobj.setopt(pycurl.CONNECTTIMEOUT, 30)
			curlobj.setopt(pycurl.TCP_KEEPALIVE, 1)

			curlobj.setopt(pycurl.USERPWD, "{0}:{1}".format(camera["user"], camera["pass"]))
			curlobj.setopt(pycurl.WRITEFUNCTION, dahuacam.on_receive)

you forgot to configure in app.yaml

Example configuration:
DahuaMQTT:
  class: DahuaMQTT
  module: dahua_mqtt
  cameras:
    - host: 192.168.0.1
      port: 80
      user: user
      pass: pass
      topic: cameras/1
      events: VideoMotion,VideoBlind,VideoLoss,AlarmLocal,....
    - host: 192.168.0.2
      port: 80
      user: user
      pass: pass
      topic: cameras/2
      events: VideoMotion,VideoBlind,VideoLoss,AlarmLocal,....

glad you got pycurl finally installed

I’m a dumb arse!! I totally see the example config in the .py file now I’m looking! Thanks for that.

Seems to be working now but despite wire cross detection configured, no MQTT events. Hmmm…

Tryed too: following log
in MQTT FX topic “cameras/dahua/VideoMotion” (I changed “1” to “dahua” in apps.yaml) gives nothing.
Mqtt discovery is enabled.
Maybe I should change topic for Hassio as “homeassistant/cameras/dahua” ??

  • 1 question: is that normal that on every HASSIO reboot or AppDaemon restart action , AppDaemon do installation of all mentioned packages again? It takes so much time… Is that normal behaviour?
    And some strange happens in logs - on every few restarts it installs pip 10, and pip 19, then uninstall pip 10 etc etc etc.
