Caveates
Unfortunately, the DS2409 is "Not Recommended for new designs" and is apparently being phased out.
The branching within OWFS directories is unique, but creates some difficulties -- selecting and searching subbranches requires extra addressing information for every step. Also, it's harder to find devices.
For just the electrical reliability of multiple 1-wire lines consider:
- LINK-HUB (IButtonLink)
- HA7Net (EDS)
- OW-SERVER-ENET (EDS)
- OW-SERVER-ENET-2 (EDS)
- 4 Channel Hub (Hobby Boards)
To have control over the individual branches:
- OW-SERVER-ENET-2
- 4 Channel Hub
