Adding cameras from remote computers (e.g. pi + webcam) into Home Assistant can sometimes be a hassle, and I also found options such as Motion to be overkill much of the time. For example I wanted to get my mac webcam integrated into HA and ended up battling with ffmpeg, before giving up. Well it turns out that openCV does a pretty good job of connecting to most cameras, and that you can use MQTT to get those images into HA without much config at all Furthermore you can create an image processing pipeline by chaining together MQTT topics, so you could for example crop, rotate and enhance an image using openCV/skimage before displaying them in HA. I published this project in the repo below, it has a few rough edges but if there is interest in it I will continue to develop it. Cheers
