My point exactly… You can initially set the speed to 0.5 as there’s no error state and the fan will operate at 50%. If an errors occurs after that, the system cannot set the speed to max_speed as it’s at 50%…
However, if I try to set the shutdown_speed to 1.0 in config, it reports “shutdown value must be 0.0 or 1.0 on soft pwm” … Check the code above, I am trying to set it to 1.0 ?
Ah, I think I see now… I must have max_speed set to 1.0 in order to set shutdown_speed to 1.0
But that seems strange, it means I can’t operate a fan below max if I want it to keep spinning after error condition. If I operate any fan at say 50% and an error occurs, it will stop… fine but perhaps it would be better/safer if it continued at full speed…
Edit: Just confirmed it, you must set max_speed to 1.0 if you intend to set shutdown_speed to 1.0, in other words, if a fans max_speed is below 1.0, it will shutoff in the event of an error…
