I may have found a reason why we are all having issues with the not being able to see the system temps anymore.
SYSTEM INFO:
unraid: v6.8.3
M/B: ASUSTeK COMPUTER INC. Z10PA-U8 Series Version Rev 1.xx
BIOS: American Megatrends Inc. Version 3801. Dated: 05/23/2019
CPU: Intel® Xeon® CPU E5-2620 v4 @ 2.10GHz
First I ran pwmconfig:
Found the following devices:
hwmon0/device is power_meter
hwmon1 is nct7904
hwmon2 is coretemp
hwmon3 is nct6779
Found the following PWM controls:
hwmon1/pwm1 current value: 255
hwmon1/pwm2 current value: 76
hwmon1/pwm2 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) n
hwmon1/pwm3 current value: 76
hwmon1/pwm3 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) n
hwmon1/pwm4 current value: 5
hwmon3/pwm1 current value: 10
hwmon3/pwm2 current value: 0
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon1/fan1_input current speed: 1412 RPM
hwmon1/fan2_input current speed: 0 ... skipping!
hwmon1/fan3_input current speed: 872 RPM
hwmon1/fan4_input current speed: 852 RPM
hwmon1/fan5_input current speed: 0 ... skipping!
hwmon1/fan6_input current speed: 0 ... skipping!
hwmon1/fan7_input current speed: 954 RPM
hwmon1/fan8_input current speed: 0 ... skipping!
hwmon3/fan1_input current speed: 0 ... skipping!
hwmon3/fan2_input current speed: 0 ... skipping!
So I can see that the system can see what sensors and fans I have.
I then ran: 'dmesg | grep NCT6779'
# dmesg | grep NCT6779
[ 49.798332] nct6775: Found NCT6779D or compatible chip at 0x2e:0x290

[87679.600329] nct6775: Found NCT6779D or compatible chip at 0x2e:0x290
I next ran the command 'sensors' and it gave me a load of errors against the 'bus name'
~# sensors
Error: File /etc/sensors.d/sensors.conf, line 14: Undeclared bus id referenced
Error: File /etc/sensors.d/sensors.conf, line 16: Undeclared bus id referenced
Error: File /etc/sensors.d/sensors.conf, line 18: Undeclared bus id referenced

Error: File /etc/sensors.d/sensors.conf, line 30: Undeclared bus id referenced
Error: File /etc/sensors.d/sensors.conf, line 32: Undeclared bus id referenced
sensors_init: Can't parse bus name
On opening up the 'sensors.conf' file and looking at the referenced error lines I can see a reference to '0-2d'
# sensors

chip "nct7904-i2c-0-2d"
label "fan7" "Array Fan"
so I make changes from '0-2d' to '02d', thereby removing the minus char.
I go back into settings>system temp and it now shows me all the settings!!!!!
I choose all the fans, HOWEVER... when I click on APPLY. The page reloads and the temperature settings have reset and NOTHING shows and the sensors file is reset to show references to '0-2d' - argh!
BUT.... If I do all the above and NOT click on APPY', the cpu and motherboard temps NOW show up in UNRAID.
and one last update , if you REBOOT then it stops working again and I had to do the above again.
SO, clearly further investigation around this whole situation is required from both Limetech and Bonienl
