When using this (very useful!!) script for my Iskra ME-162, I found that I always get nill for the current production. I found that line 259 of the executable contains an error. It now reads:
production = int((current_readings.total_return - current_readings.total_return) / interval * 3600)
which by definition is nill. Obviously the second current_readings.total_return should be previous_readings.total_return. This should give the correct current production.
