Replacement for Hardware Growler?

Having just made the leap to Sierra (10.12.2), I've discovered that one of my favorite add-ons is behaving funkily, and wonder if any of you have discovered an alternative. I don't actually care that much about Growl itself, but Hardware Growler is a wonderful add-on to Growl that gives you all sorts of info about what's going on behind the scenes with the hardware you connect/disconnect from it. Everything from USB, Bluetooth & Firewire to Network, Power and Volume mounting/unmounting. Since it's primarily just reporting things that system doing & noticing, I would imagine there might be something like an Automator workflow, integrated with some command line tools that could replace it? ---- I'm using version 2.1.3 of Growl, which is the latest, and what I was using in El Capitan. HardwareGrowler is at version 2.2, and again, that's what I have been using for quite some time.
