I've started long time ago to create surely but slowly and no wire attached temperatures sensor and I wanted a place to post my progress.

This was just extremely perfect!
But mine need to be more robust so a little more deeper reserch make me feel on an nice firmware of MQTT protocole handler for esp called Homie.
Homie is awesome and at this moment, some great-opensource-developers are currently working hard on next version (2.0.0) so for the moment I played with V1.5 witch is really not so bad.
Till then I was waiting for my components to arrive (from china...) I have read alot on configurating it on esp8266.
