I would like to present my solution for the control of my fridge / freezer.
Is not perfect, but it works.

Use at your own risk.
Change suggestions are welcome.

The PHP script is vulnable to SQL injection, but if you protect it with a key or something that dont really matter.
About SQL injection I have not though about.
Thanks for the tip.
Norbert,
Can you please post the circuit you used for the one wire as I have a application. I have been using a arduino and have them monitoring but would love to scrap the arduino completely.
Thanks in advance
