I have a large dyno fan which is controlled via Vfd and manually speed controlled via potentiometer. 


I have now built a custom pcb which basically allows me to control over Bluetooth. I can send simple serial command via dyno pc to control speed 



I would like yourdyno to control fan speed based on speed or rpm, which would require a plugin... Which is not my strong point lol


Anyone with a vfd controlled dyno fan can replicate the hardware very cheaply... Just an esp32 dev board, pwm module. 


Happy to post up and also coding which of course would be written to suit how yourdyno would send data..
