I would suggest using a separate computer running Apache to accomplish this in conjunction with the Generic TCP driver. Have the generic TCP drive hit a URL that you create on a Linux web server, a Raspberry Pi will do for this. Have that execute the ssh command that you need when that URL gets hit. I do similar stuff today with my C4 system - I have it launch Python scripts to do various things, including allowing me to interface with my Tesla, like starting/stopping chargin, turnin on the clmiate system, etc.
