Making a door-knock alert?
I am interested in having Twine send an alert whenever someone knocks on my front door when I am not home. However, this would also be set off by me entering/exiting. I was thinking about a way that my phone could 'check-in' to a database whenever it enters/leaves my home network. Then, if the twine registers a vibration alert to the same database, there could be a rule to either send a text or not depending on whether I am home.
Does anyone have an idea how to best go about doing this?
