Uploading Arduino Sketch to ANAVI Thermometer

Step by step instruction for compiling and uploading firmware to ANAVI Thermometer using Arduino IDE. ANAVI Thermometer combines open source hardware with free and open source software. It is powered by ESP8266.

Great stuff! I managed to compile and update the firmware by following your tutorial.
I would like to play with and customize the sketch to my needs, like adding a timestamp to the payload, adjust timezone, etc...
However, Arduino is new to me and I am a bit afraid of messing things up. A few questions about it:

1 - If something goes wrong, can it brick the thermometer?
2 - Is there a recovery procedure in that case?
3 - Would it be possible to test it on a virtual machine instead of flashing it directly to Arduino?

If you have any recommended material for beginners I will be very grateful!
I love this thermometer and hopefully will be able to create my own server and mobile app. :)

Just received the Miracle Controller and you mention to flash with the latest, so I followed the steps provided. Tried to compile on both Mac and PC, but I always get errors. Here's the error I receive on the PC:

Error compiling for board Generic ESP8266 Module.

This report would have more information with

option enabled in File -> Preferences.

The board is fried after a flash attempt. Suggestions?
