Deadman outlet

I wish someone would make an outlet that had to be pinged to stay on. I have a space heater that I’d put on an outlet, if I knew it would turn off if my hub took a break.

Anyone know of any?

There are some, actually. The ones I know of are pretty pricey though.

These guys make some, and I know there are a few other manufacturers but I don't have their info handy.

Yikes, a bit much for what I want, I guess I could use this to reboot the hub!
Of course, I am trying to guard against a rare occurrence.
