For most anything that can be connected to some kind of network (ethernet, wifi, zigbee, IR, z-wave) HA can do just about anything you can imagine. I keep thinking of new stuff that’s not hard to implement, for instance I just set up volume leveling for difference sources on my old IR-only receiver so we don’t get blasted if someone leaves the volume up high.
Since HA can use almost any info from the web you can use it to do things like control a swamp cooler based on outdoor temperature and dew point. Using windows sensors (from an alarm system or zigbee) you can shut off the heat or AC when the windows have been left open for a specific amount of time and turn them back on with the windows are closed. You can send a notification if you leave and forget to set your home alarm.
It looks like your Pi2 might be able to run the software, but that hardware was introduced 11 years ago and it wasn’t a powerful device even then. HA is also depreciating 32bit hardware. If it doesn’t work on that and you don’t want to buy new (or used) hardware, installing a HA VM on another PC might be a good way to start.
