I'm considering to setup a simple wifi controlled door entry system. Currently i have a door which can be opened with a key, or you can be buzzed in via the intercom.
I'd like to include a switch to release the latch that's activated by pressing a button on a mobile app.
It could get more sophisticated, but that would be a start to cover the hardware side.
I'd need to install a wifi-connected unit that can trigger a 12V switch.
Any suggestions / ideas how to start?
Maybe something from here: http://netio.davideickhoff.de/en/
Did some more googling and seems there's a lot out there. Still it's murky waters for me.
I'm wandering for the switch if something as simple at this would do it...
This one seems to be for switching AC devices, but something similar maybe.
