IoT thermometer offiline

I did few changes to my IoT thermometer firmware (ESP8266 + Arduino IDE) and something broke: it does not read the DS18B20 anymore. I tried two 18B20: their address is read, which confirms they work and are connected properly, but temperature data is never returned.

Throughout the month since I changed the firmware I updated the Arduino IDE, the ESP8266 libraries and did a Windows update too. Too much to debug in a single night.

As a result my ThingSpeak thermometer is offline.
