I am considering building an all-1-wire system and am wondering if someone can point me to any 1-wire devices that can be used as addressable switches to toggle 5V on or off?
(yes, I know it would be trivial to have arduino toggle its' outputs.......)
Maxim bought Dallas Semiconductor so they own the 1-Wire name. http://www.maximintegrated.com/products/1-wire/
It looks like there is no 1-Wire output device.
1-Wire Devices
Memory: EPROM, EEPROM, ROM (22)
Temperature Sensors and Temperature Switches (10)
1-Wire Interface Products (6)
Timekeeping and Real-Time Clocks (1)
Battery Protectors, Selectors, and Monitors (10)
Sure, but other manufactures make devices as well. Could a PIO device do the job?

Take a look at the DS2406 and DS2408.
PapaG, thanks, I took a look, it looks fairly complex to use those to just pin a high or low value to the PIO outputs?

If 1-Wire is too complex, then perhaps you should consider not using it.
Is I2C not an option? not exactly 1 wire but I2C can control up to 127 modules each of them controlling 8 relays.
what is the distance between controller and the relays? thinking rs485 ?
