Jean, Can you take a decision on this please and then write a bit of specification? Then I can make the uGuru driver implement the specification and submit it for merging. What I need for specification if you decide for the one file per sensor is the names to use for: -alarm -alarm enable/disable -beep on alarm enable/disable -shutdown on alarm enable/disable And also the names for alarm and alarm enable/disable for sensors with more then 1 alarm, specifically with a volt low and a volt high alarm. Thanks & Regards, Hans
