Call doorbell on local network instead going through the hikconnect cloud

[bydga]

Hi,

thanks for the great module, I recently bought a Hikvision doorbell and integrating the buzzer into HK is a great possibility for me (i can remove the shelly that has been proxying the relay signal from doorbell to the outside-gate 🙂 )

However i just discovered you are calling the remote hikvision api to control the doorbell relay. And I found a command that can be used to do the same action - but via local network 🙂 (btw my outdoor station is DS-KV6113-WPE1)

 curl -i --digest -u admin:pass -X PUT -d '<RemoteControlDoor><cmd>open</cmd></RemoteControlDoor>' http://192.168.0.117/ISAPI/AccessControl/RemoteControl/door/1

My idea of a smarthome is not to be dependent on an internet connection - without internet, remote control is obviously lost, but when you are at home, everything should work as usual.

So this is more like a feature idea/proposal, how to make your module better. PLus i've read in another issue that you are calling some undocumented reverse-engineered api - so they can change it anytime and this module will break :/

I haven't developed anything for HB yet, but if i find some time, i will try to help and send you a PR 🙂

Hi @bydga !

Thanks for the idea. The thing is that I cannot access the admin panel of my intercom so I cannot enable the ISAPI interface what you mentioned (I'm not the owner of the intercom, I live in a block with many flats). So using the ISAPI interface is not possible for me (and many others same situation as me) that's why I implemented this through hik-connect with an unofficial API.

If I would have access I would create a new plugin without the relying the cloud and using the official API, but this plugin is intended for folks like me who cannot access ISAPI for some reason.

Ah, ok. got it 🙂 Funny how eveyone has completely different needs/use cases for just a doorbell :D So i will probably end up writing my own module. But till then, i will surely be using yours, thanks!
