This is not what I want to suggest. I just want to point out that Hassio HassOS has governor \"powersafe\" as default which holds the RPi always at the lowest default cpu frequency (e.g. on RPi 3B+ it is 600 MHz and on RPi 2 it is 700 MHz). This is a performance issue. If this is switched to default \"ondemand\" then it will dynamically switch to higher frequency if needed and falls back to lowest frequency if the power is not needed. This will do no harm to the hardware..."}}
