Auto arm will only do awayArm atm until Hikvision adds new option for it
But if you have RaspberryPi4 or something similar where you can run some service app 0-24, it can be done using ISAPI endpoints and payload to control Alarm central.
After managing to trigger StayArm and Disarm, then you can code logic when.
Yes it does require authentication, but unlike other hikvision devices, simple digest auth wont work. You have to do it manually. If i were to copy paste here, i would probably end up with 300 lines of code.
There is github repo that made this work with home assistant in python, i just remade in c# to suit my integration.
