Magnetic Reed Switch Esp8266

I wanted to detect when my freezer door opens or closes to get more data on when the tempurature drops. This also is an attempt at trying to create an alarm if the door is not closed all the way.

Tracking my refrigerators tempurature was a fun way to get started. Now, I cant stop thinking or more importantly, buying, different small sensors to measure the world around me. I should start back in the beginning of how this all started.
