I have an H96 Pro (S912 version) and I need to add a fan to it due to overheating while playing certain video files. The back of the dongle is well vented, so it's no problem to attach a small USB powered fan. But, since the USB power is pass through on this device, all USB ports remain powered as long as there is power connected to the device. This means the fan stays running all the time, even when the device has been shut down or has gone into sleep/standby mode. I want the fan to turn off when the device is in standby/sleep mode so the fan doesn't collect and introduce dust into the device during the 22 hours of the day that I'm not using it, and also to prolong the life of the fan.
Unfortunately, I can't find a way to get a fan to turn on and off with the dongle. Regular TV boxes have a status led that changes colors which could be used to control a fan, but this dongle only has one red light that stays lit all the time. I've been looking into a USB relay switch, which can be controlled through a serial terminal app in Android, but that would require running the app and entering commands every time to turn the fan on and off. I would greatly prefer something automatic. Does anyone here have any suggestions on how this might be achieved?
