Hello Community, I’m thrilled to share my successful experience in configuring multiple USB bus masters with OWFS. After encountering some challenges, I managed to set up a star 1-wire bus system, which has significantly improved my sensor network reliability. Here’s how I did it:
Initially, I was using a single ds9490r USB stick as my bus master. However, due to my house layout, I needed to switch to a star configuration with two USB bus masters connected to my Raspberry Pi. The key was correctly configuring the owfs.conf file to recognize both bus masters.
For the ds9490r, my configuration was:
server: usb = all
When I switched to the Esera USB bus master, I updated it to:
server: device = /dev/ttyUSB0
To make both work seamlessly, I had to list each device explicitly. Here’s the final setup in owfs.conf:
server: device = /dev/ttyUSB0, /dev/ttyUSB1
This change allowed both bus masters to communicate without conflicts. I also ensured proper power supply to each master to avoid voltage drops, which was crucial for stable operation.
I’d love to hear if others have implemented similar setups or have tips for optimizing a star bus system. Happy wiring everyone!
