Thanks for replies so far re both systat and hw.sensors.acpiac*
In both of the cases below I was watching either `sysctl hw.sensors' or `systat sens 1' and could see eg acpiac0.indicator0 change promptly, but there was no indication from sensorsd that the sensor exists. ## no sensorsd.conf file: $ doas sensorsd -c1 & tail -0f /var/log/daemon Sep 19 16:06:45 workpad sensorsd[9181]: startup, system has 22 sensors Sep 19 16:06:48 workpad sensorsd[9181]: acpibat0.watthour3: 33.54 Wh, OK Sep 19 16:06:48 workpad sensorsd[9181]: acpibat0.raw0: 2, OK ## with a sensorsd.conf file $ doas sensorsd -c1 & tail -0f /var/log/daemon Sep 20 09:46:34 workpad sensorsd[88233]: startup, system has 22 sensors Sep 20 09:46:37 workpad sensorsd[29023]: acpibat0.watthour3: 35.45 Wh, OK Sep 20 09:46:37 workpad sensorsd[29023]: acpibat0.watthour3: within limits: 35.45 Wh Sep 20 09:46:37 workpad sensorsd[29023]: acpibat0.raw0: 0, OK ## sensorsd.conf hw.sensors.acpibat0.watthour3:low=3:command=/home/tomr/bin/sensors.sh %l %s %x %t %n %2 %3 %4 hw.sensors.acpiac0.indicator0:command=/home/tom/bin/sensors.sh %l %s %x %t %n %2 %3 %4 hw.sensors.acpibat0.raw0:command=/home/tomr/bin/sensors.sh %l %s %x %t %n %2 %3 %4 (sensors.sh just writes its invocation out to a file) ## hw.sensors $ sysctl hw.sensors hw.sensors.cpu0.temp0=65.00 degC hw.sensors.acpitz0.temp0=63.00 degC (zone temperature) hw.sensors.acpibtn0.indicator0=On (lid open) hw.sensors.acpibat0.volt0=14.80 VDC (voltage) hw.sensors.acpibat0.volt1=16.49 VDC (current voltage) hw.sensors.acpibat0.power0=0.00 W (rate) hw.sensors.acpibat0.watthour0=35.45 Wh (last full capacity) hw.sensors.acpibat0.watthour1=1.77 Wh (warning capacity) hw.sensors.acpibat0.watthour2=0.20 Wh (low capacity) hw.sensors.acpibat0.watthour3=35.45 Wh (remaining capacity), OK hw.sensors.acpibat0.watthour4=46.03 Wh (design capacity) hw.sensors.acpibat0.raw0=0 (battery full), OK hw.sensors.acpiac0.indicator0=On (power supply) hw.sensors.acpithinkpad0.fan0=3680 RPM (apciac0.indicator0 responds reliably to un/plugging) ## dmesg OpenBSD 6.0 (GENERIC.MP) #2319: Tue Jul 26 13:00:43 MDT 2016 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 8255741952 (7873MB) avail mem = 8001060864 (7630MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xdae9d000 (68 entries) bios0: vendor LENOVO version "G6ET96WW (2.56 )" date 04/29/2013 bios0: LENOVO 34486T7 acpi0 at bios0: rev 2 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP TCPA SSDT SSDT SSDT HPET APIC MCFG ECDT FPDT ASF!
