Hi all, I’m a long time lurker, first time sharer.
A little while ago I introduced some Xiaofang wifi IP cameras into my ecosystem. I am currently using the very average but sufficiently functional Synology Surveillance Station as an NVR for the CCTV cameras on the outside and the XiaoFang cameras on the inside of my house.
As neither my wife nor I are overly please with the idea of candid CCTV footage of us walking around the house in varying states of dress I was keen to implement a reliable home/away setup with the NVR. Synology provide this functionality using geofencing and the Synology app, however our experience with this was patchy at best.
We already have a fully functioning and almost perfectly reliable occupancy state using home-assistant so I wanted to lean on this. As best as I could gather the Synology Surveillance Station component does not yet provide that functionality, however there is an API available, so a layman like myself might be able to bash a couple of the correctly shaped and coloured rocks together, and produce a workable solution.
So onto the kludge!
I’ve created a rather inelegant flow in node-red that authenticates with the API and then calls the required state. I am sure there are much more optimised and cleaner ways to implement this, and I an eager to hear them so please share!

I just use a standard MQTT switch on the HA side of things.
- platform: mqtt
name: Synology Home Mode
command_topic: "device/synodevice/homemode/cmd"
state_topic: "device/synodevice/homemode/stat"
payload_on: "on"
payload_off: "off"
retain: true
And a basic automation to turn Synology Home-Mode ‘off’ (thus enabling recording on the internal cameras)
- alias: House Away Mode
trigger:
- platform: state
entity_id: sensor.anyone_home
to: 'Away'
for: 00:02:00
action:
- service: switch.turn_off
data:
entity_id:
- switch.synology_home_mode
- alias: House Home Mode
trigger:
- platform: state
entity_id: sensor.anyone_home
to: 'Home'
action:
- service: switch.turn_on
entity_id:
- switch.synology_home_mode
I hope this is useful to someone, and I am keen to receive recommendations or criticism 
Cheers.
