Hey guys! I was wondering, how does RNOS get voltage info. I'm getting an e-mail from time to time, informing me that the voltage in enclousure is lover than 12V. I want to get the information by myself and record it in log.There are no sensors, acpi, nor dmidecode commands. I've checked at /sys/class/power_supply - it's empty.Anyway, I'm pretty sure it's using some device / kernel module to probe voltage. Any ideas?

We are using libsensors directly. The sensors command will work if you install the appropriate package (lm-sensors).

Which model is this? Is disk spin down enabled? Does warning timing have certain pattern? For example, if disk spin down is enabled, does warning ususlly come when disks wake up after long idle? What is warning reading ( < 10.8V ?) Thanks.

  Yeah, after posting this message, I came upon this thread. Conclusion was simple: if there are sensors configs, then it has to be present. I've searched whole system and found libsensors, so the answer was quite obvious.
  Anyway, thank you for answering :-) If there are libraries, I might try to use them instead of installing binaries.
  
  c3po, this is a problem of my PSU. I have made a UPS-like buffer supply, which I mentioned in my previous thread. I've put a digital voltmeter in it to keep track of voltage being supplied. It's strange, because I'm getting those messages almost daily - actually, without any reason. The lowest voltage reported was 10.61V and I have never seen it to drop below 11.8V on voltmeter (even at the time the email was sent). Thats why i want to record the values in log.
