The EZIO8SA supports a single 1-wire temp sensor. Although there were plans to add addition 1-wire sensor support years ago I believe those plans were scrapped long ago.
The 1-wire temp cannot be access in an ISY Program. Same it true for Analog Input analog values. Neither the 1-wire input nor the 2 analog inputs can be configured for the optional non digital operation and the respective values cannot be accessed by an ISY Program.
UDI did a post today indicating no plans to add support for either 1-wire or analog.
