ESP8266 Magnetic Switch Deep Freezer Monitor

Setup an ESP8266 as a Deep Freezer Monitor using a magnetic switch. The ESP8266 will start sending me emails and text messages if the Deep Freezer has been open for more than 1 minute. I also wanted to log when the Deep Freezer was open. So a web service is called to log the data to a database.

If the Deep Freezer has been opened for over a minute I get a text and an email. Then the counter resets. If if is still open after another minute I get another text and email. In version 2 I am planning to add a temperature probe I can place in the deep freeze. Then I will take some random temp samples to monitor the temperature.
