Hi,
The 1-wire integration can be setup using three different methods:
- OWFS (uses FUSE to local filesystem)
- OWServer (over the network)
- SysBus
Even though each component has a unique hardware ID, the three methods use a slightly different way to generate a unique id:
- OWFS will generate
{owfs_root}/{hardware_id}/{sensor_type} - OWServer will generate
/{hardware_id}/{sensor_type} - SysBus will generate
/sys/bus/w1/devices/{hardware_id}/w1_slave
Example with hardware device “12.ABC000000000”, sensor type “temperature”
- OWFS will generate
/mnt/owfs/12.ABC000000000/temperature - OWServer will generate
/12.ABC000000000/temperature - SysBus will generate
/sys/bus/w1/devices/12-ABC000000000/w1_slave
As I am attempting to create switch and binary_sensor platforms for onewire, should these be standardised? I am tempted to use the OWServer method: “/12.ABC000000000/temperature” for all entities but this would mean a breaking change for those using OWFS or SysBus.
