BPi-M2+ Temperature displayed at boot (where to find it)

Hi,

As displayed at boot (when terminal connection used through SSH) where can I find the CPU temparature after the boot ?

Because I tried to check the content of files :

cat /sys/devices/virtual/thermal/thermal_zone0/temp

and

cat /sys/devices/virtual/thermal/thermal_zone1/temp

It well displayed it but when I use the "sensors" command line (comming  from "lm-sensors" package installation) and even after having done the recommended "sensors-detect" command line (and answered YES at all the questions to be sure having found all the potentially existing sensors), the "sensors" command line just returned this

Sincerely thanks
