So thanks Flick, they gave me access to the IFTTT applet.
I have it setup now so I when the price of power is going to be over X (I have to edit the IFTTT applet to adjust X), it sends a Web request to my Home Assistant, which then triggers the 3 thermostats in my house to turn off. So the poor kids will freeze, but at least I won't be paying megabucks for Power.
Very easy to setup!
How about sending a text to your kids at the same time to put on some warm clothing, or, have that shower now before the water goes cold!
