Home Assistant vs Insteon Hub

Hello,

As I have not found a youtube video on this. Can somebody clarify the differences between Home assistant and Insteon hub? Just to put the question in context: I’m looking to create my own security system and I need the system to

  • be relatively easy to set up and maintain
  • connect with many devices located far apart each other and with walls in between
  • send sms and emails to many people when alert is triggered
  • have no or little monthly subscription costs
  • be robust when integrating additional sensors from different manufacturers

Additional question: One Insteon video explains that they are able to increase the range by having nodes communicating through the power lines. Can home assistant integrate such nodes as well?

Thank you very much for your answers.
