Amazon had these little Dash buttons about 10 years ago. The goal was you would click one, and it would re-order that product from Amazon. Many were branded.

Basically just a wifi button. I hacked one so I could, in my brain fog, record the moment i started and finished feeding my infant by sending a ping to a server via a simple click.

There's a bunch up on eBay. Could probably 3M tape one beside your door. Easy solution, esp if it's shielded from rain.
