Christian, The 1921 is a work in progress, but getting closer. We'll have to update the two in lockstep.
Actually, the 1923 seems to be a superset of the 1922, perhaps your code should support both. The 1922/1923 use the password protection similar to the 1977, so I thought we'd use the same syntax. (passwords cached in database as a write-only property).

Many things are similar to DS1921 (with missions etc), but many commands were different to I had to create a ow_1923.c for it. My main problem is that I managed to read address 0x0200 from that device once, then I tried to start a humidity conversion and read the result... After that it was not possible to get any other response but 0xFF... All ow_r_mem commands result into 0xFF on all addresses, and then I found a small notice in the documentation. "A temperature or humidity conversion must not be attempted while the RTC oscillator is stopped. This causes the device to enter en unrecoverable state" I never touched this EOSC (Enable oscillator) on the device, so I wonder if this could result into a broken 1-wire device?? Have there been any other devices that could hang forever? I have tried to disconnect the device for several hours, but it still doesn't work. First read of address 0x200-0x0220 worked (all time registers were zero and crc was correct too) Read: sz=37 690002000000000000000000000000207F9F7900FC00C070C8000000000000000000008E66 DATE_READ data= 0, 0, 0, 0, 0, 0, 0 When I read Latest humidity result for example, it just return 0xFF.
