Capture traffic of device connected to the router

I have a device that is connected to my own router. I want to be able to see the http(s) requests being made by the device. However there is no way for me to set the device to use a proxy server. From what I researched this may be possible by using a transparent proxy. But what if the requests are in https? Would that still be possible?

Yes, transparent mode is the correct way but you have to install the mitmproxy’s certificate in your device.
