Workaround to wake up iOS device from terminal

I was trying to create the iOS device test farm, and in order to reduce consumption, I put them to sleep with idevicediagnostics. But, in order to wake them up, I have to do it manually. I have read man pages of all the commands associated with the libimobiledevice and could not find how to wake up the iOS. Is there any command or tool that could help in this process?
