Im dealing in my head some project to show postman a PIN code to confirm the package delivered.
So for this kind of project I have some guides need to follow:
- Must be the most low powered possible (remote location)
- Must show to post guy 2 Lines (Tracking number + pin) (RD123456789PT + PIN)
- Can have more lines for more codes…
- This codes I have a way to send them remotely from HA or from iPhone
- The best option is remove the codes remotely.
- To save power maybe some switch on door or pressing…
Any idea?
I do not try nothing… maybe need some advice on parts or code…
discuss the crazy ideia…
