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?

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.

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…

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.
