In theory, there's a lot of 1-Wire devices out there, but in reality almost everyone uses 1-Wire for DS18b20 temperature sensors. the long wire lengths and ease of 'chaining' by sharing a single bus wire makes it perfectly fine for this purpose. you can bitbang 1Wire on most microcontrollers, and some SBCs like Raspberry Pi have kernel module support.
