Eventually I used dmesg to see the order of enumeration: [0.64] tmp102 1-004a: initialized [0.64] tmp102 1-0049: error reading config register [0.64] tmp102: probe of 1-0049 failed with error -121 [0.64] tmp102 1-0048: initialized But I think it's quite bad method.

I remember writing a libsensors-based name look-up tool years ago.

But I was looking for something to check in /sys or /proc to get the matching. Probably if libsensor somehow knows the mapping it also looks there, No ? > Guenter

How to detect which device is mapped to hwmonX ?
Hello, I have several nodes /sys/class/hwmon/hwmonX , but checking the fields I could not find yet a way how to identify a device (for example i2c address) to the given mapping of hwmonX. Is there a way to find out which device is mapped to which hwmonX ? Thanks, ran
