[SOLVED] lm_sensors: custom label won't apply

I need to differentiate temp labels between my NVMEs.

$ sensors -u
spd5118-i2c-13-51
Adapter: SMBus PIIX4 adapter port 0 at 0b00
temp1:
  temp1_input: 45.250
  temp1_max: 55.000
  temp1_min: 0.000

  temp1_lcrit: 0.000
  temp1_max_alarm: 0.000
  temp1_min_alarm: 0.000
  temp1_crit_alarm: 0.000

  temp2_min: -273.150
Sensor 2:

  temp3_min: -273.150

  temp1_max: 81.850
  temp1_min: -273.150
  temp1_crit: 84.850
  temp1_alarm: 0.000
Sensor 1:
  temp2_input: 51.850
  temp2_max: 65261.850
  temp2_min: -273.150
Sensor 2:
  temp3_input: 58.850
  temp3_max: 65261.850
  temp3_min: -273.150

Following the wiki, I wrote those lines in "/etc/sensors.d/custom_labels":

chip "nvme-pci-0a00"
  label Composite "NVME1"

Restarted lm_sensors.service. This doesn't override the default label.

Re: [SOLVED] lm_sensors: custom label won't apply

Hello.

In lm_sensors, the different listed sensors, such as Composite, have raw names and friendly names and lm_services isn't very clear which of the name types they use for each solution. Your nvme-pci-0a00 chip for example contains the sensor friendly name of "Composite" which is composed of "temp1" raw sensor name.
Thus, changing your custom_labels to the following

chip "nvme-pci-0a00"
  label temp1 "NVME1"

then restarting all

 sudo systemctl restart lm_sensors
sudo systemctl restart sensord

then running

 sensors | grep -A3 "nvme*" 

should confirm everything as working as intended. The composite label now says "NVME1" instead of "Composite"

Thank you. I had tried "temp1_input" but hadn't thought to simply put "temp1".
