As far as I understand, DS18B20 is a serial device and A1/A0 are not serial ports, they are PMW/ADC, at least on Espruino Board.
Anyway, on my Espruino I tested same with port B7, and its not working.
Search failes to find the sensor.
Upgraded to 1v46 did not help.
Downgraded to 1v43 (r1.3) and it works, at least search works and I get a device back.
But 1V43 seems to have problems somewhere around "this", get an error that EOF was found where } was expected (???)
So this is not a solution for the problem.
