Help to turn on/off At Home using webhook
**Describe the bug**
Not a bug, looking for help.
Trying to use webhook to turn on/off _At Home_ mode

Idea is to add a http or webhook button in homebridge to control this after knowing what I’m missing

**Expected behavior**
I'd like this section shows you exactly the link to use (including IP or whatever’s missing if so) so dumb users like me can just copy/paste
