Hi and welcome to the forum!
I think that a user of the Spanish forum has tried to install the sketches on ESP8266, and it worked well.
I did not test it personally (because I don’t have an ESP8266 yet, I will have to buy a couple of them).
If you manage to install the sketch in a ESP8266, you can query the esp by invoking the url on a browser (http://ipofyouresp8266), and if you receive a Json object with information regarding the temperature and so on, then it will work with the project 😉
I’m sorry that I don’t can help you any further.
Regards
PS: If it works, please let us know 🙂
