I have pushed a new version to
my github and encourage all that are using the script to update. There are a few small bugs fixed and the tuning process should be more accurate and even faster in finding the right values for each of your chains.
A nice feature would be to keep the script running in an infinite loop to always adjust the voltage. The ambient temperature differs quite a bit for my miners and therefore the optimal voltage is different from time to time.
I see your point and considered it but the changes in the script would be quite big with the chance of introducing many new and unneeded bugs. You can already easily achieve the same by a simple shell loop like:
while true; do ./l3plus_autotune.py -i 10.10.10.33; sleep 900; done
The above line starts the tuning script and waits until it exits, sleeps then 900s (15min) and restarts the script again in a never ending loop (or until you hit CTRL-C).
Happy tuning.
BTW: If people with wattmeters on their miners would post their measurements (before and after tuning and with the respective frequency and voltage-setting) I could try to interpolate watt savings and print a very rough estimate on the savings in Watt for each run of the script.
