Some sensors MAY actually work. This does not discard what i wrote before (I tested them all), but: For some reason some of the sensors gives invalid response to ‚Power supply’ command. They always respond as they are parasite-powered. Some devices (ex. mine) do check that and reported them as invalid. However I tested all ‚Invalid’ with osciloscope. Some of them gave some response, so i took the deeper test.
If you’re planning to order cheap DS18B20 sensors from AliExpress – keep in mind that irrationally low price (less than $0.8 / pc) smells really fishy.
Manufacturer price for 1k is $1.18.
