Implementing the protocol to read temperature and humidity eats all your memory on the ESP8266 and there is nothing left if you want to support MQTT messaging. However, and I2C sensor works. The I2C implementation using an LM75A can be done and integrated with MQTT.

I am preparing a post with the details on what I did and will publish in http://www.horaciobouzas.com
