Shell Commands are the primary tool I use to go about doing these things. I write the scripts to perform the action(s) desired and drop them on the local PC. The shell commands are then fired off from Home Assistant via SSH (either directly in the HA dashboard a la human interaction or through automations) or via my phone through Tasker or KDE Connect (as mentioned elsewhere.)
The trickiest bit for me was setting the correct environmental variables in the scripts but then it was an excellent learning opportunity! Best of luck OP and let me know if I can provide any more info.
