  1. Yes, it's working now, thanks a lot for the quick fix!
  2. No Text on OLED-Display (Logo is ok) Today I assembled my spare Helios 4 from batch 3 (which came with the bonus OLED display) and installed Armbian_20.05.2_Helios4_buster_current_5.4.43.img - nothing else yet. Nearly the first thing I did was to install sys-oled, which works well with everything left at defaults, with the exception of text display: Every line of text is just a solid block of pixels . The graphical logo displays well, so cabling and OLED type (sh1106) seem to be correct.
  3. "armbian-config" has an option to install to SSD.
  4. I found a nice shutdown script on high HDD temperature at https://www.cyberciti.biz/tips/howto-monitor-hard-drive-temperature.html. I use a slightly enhanced version which is able to deal with sleeping drives: #!/bin/bash # Program: Monitor hard disk and shutdown system if temp >= 50 # http://www.cyberciti.biz/tips/howto-monitor-hard-drive-temperature.html # Author: nixCraft < vivek @ nixCraft DOT com > # Modified: <kramski @ web DOT de> ################################################ HDDS="/dev/sda /dev/sdb /dev/sdc" # my hdd HDT=/usr/sbin/hddtemp LOG=/usr/bin/logger DOWN=/sbin/shutdown ALERT_LEVEL=50 for disk in $HDDS do if [ -b "$disk" ]; then HDTEMP=$($HDT "$disk" | awk '{ print $4}' | awk -F '°' '{ print $1}') if [[ "$HDTEMP" =~ ^[0-9]+$ ]]; then # "$HDTEMP" is numeric, disk not sleeping if [ "$HDTEMP" -ge "$ALERT_LEVEL" ]; then $LOG "System going down as hard disk : $disk temperature $HDTEMP°C crossed its limit" sync;sync # add email code, make sure you add 2m delay # mail -s "HDD temperature >= 50 @ $(hostname)" you@domain.com </dev/null # sleep 2m # going down $DOWN -h 0 fi fi fi done
  5. Hi tuxd3v, my experience is quite different. When setting up my new box, CPU temp always was below 58 °C, so the fans never got started. (According to https://wiki.kobol.io/pwm/#configuration-file, fans only start at 70 °C CPU temp.) The inactive fans quickly led to quite high disk temps (two WD RED 8TB) of 52 °C (the upper one) and 53 °C (the lower one, directly above the board) . This seems too high given the fact WD specifies operating temps of only 0-60 °C, so one of the first things I did was to modify /etc/fancontrol to # Helios4 PWM Fan Control Configuration # Temp source : /dev/thermal-cpu INTERVAL=10 FCTEMPS=/dev/fan-j10/pwm1=/dev/thermal-cpu/temp1_input /dev/fan-j17/pwm1=/dev/thermal-cpu/temp1_input MINTEMP=/dev/fan-j10/pwm1=70 /dev/fan-j17/pwm1=70 MAXTEMP=/dev/fan-j10/pwm1=90 /dev/fan-j17/pwm1=90 MINSTART=/dev/fan-j10/pwm1=75 /dev/fan-j17/pwm1=75 MINSTOP=/dev/fan-j10/pwm1=75 /dev/fan-j17/pwm1=75 MINPWM=/dev/fan-j10/pwm1=75 /dev/fan-j17/pwm1=75 #MINPWM=0 With these settings, my fans are always running slowly and silently, but efficiently cooling my disks to not more than approx. 33 °.
  6. I have updated my lcd4linux.conf for a cheap AX206 picture frame (320x240) connected to my Helios4. If someone is interested: https://github.com/hkramski/my-lcd4linux-conf.
  7. Hi, (happy) new Helios4 owner here. I have a questing regarding power consumption: I'm running a new, clean setup based on Armbian_5.68_Helios4_Debian_stretch_next_4.14.88.img.xz. With no additional drives powered up, a cheap power meter shows the following results: System running idle: 4-5 W System halted after "poweroff": 6-7 W. With two WD Red 8TB EFAX (still unconfigured) and one SSD 128GB (root fs) I get System running idle, disks spinning: 23 W System halted after "poweroff": 9 W. Why does the halted system consume that much energy? TIA Heinz
