  1. Hi. After 2 years uptime it disconnected from wifi and was unable to reconnect even after reboot. I suspect my AC adapter has degraded. Can this SBC measure the voltage? Upd: saw this post: https://raspberrypi.stackexchange.com/questions/112122/wifi-not-connecting-depending-on-power-supply I use NetworkManager and when it starts it usually cannot connect to wifi saying that the pre-shared key is wrong, marking the connection as failed and not re-trying. In particular, the log contained a failed "asking for new key" message. Re-starting the service or manually activating the connection worked. As a workaround I created a *.conf file in /etc/NetworkManager/conf.d/ : [main] autoconnect-retries-default=0 Not sure if it helped though. One boot had a different error and a re-try. The other boot suddenly connected with the 1st attempt.
  2. I had to edit /usr/lib/armbian/armbian-hardware-monitor. Was: elif [[ -f /sys/class/hwmon/hwmon0/temp1_input && ${BOARDFAMILY} != "mvebu" ]]; then # usual convention with modern kernels ln -fs /sys/class/hwmon/hwmon0/temp1_input /etc/armbianmonitor/datasources/soctemp else # all other boards/kernels use the same sysfs node except of Actions Semi S500: [[ ${BOARDFAMILY} == s500 ]] && THERMAL_ZONE="thermal_zone1" || THERMAL_ZONE="thermal_zone0" ln -fs /sys/devices/virtual/thermal/${THERMAL_ZONE}/temp /etc/armbianmonitor/datasources/soctemp fi Now: elif [[ -f /sys/class/hwmon/hwmon0/temp1_input && ${BOARDFAMILY} != "mvebu" && ${BOARDFAMILY} != "sun8i" ]]; then # usual convention with modern kernels ln -fs /sys/class/hwmon/hwmon0/temp1_input /etc/armbianmonitor/datasources/soctemp else # all other boards/kernels use the same sysfs node except of Actions Semi S500: [[ ${BOARDFAMILY} == s500 ]] && THERMAL_ZONE="thermal_zone1" || THERMAL_ZONE="thermal_zone0" ln -fs /sys/devices/virtual/thermal/${THERMAL_ZONE}/temp /etc/armbianmonitor/datasources/soctemp fi Now thermal_zone0/temp wins over hwmon0/temp1_input
  3. specialist383 did you manage to solve this mystery? I'm having the same problem. If Orange Pi Lite with Armbian 21.02.1 is able to detect an external 1-wire thermal sensor, then the "CPU temp" line shown at ssh login is actually the outside temperature.
