Hello all, wanted to share a wonderful product I found by accident
Enclosed AC/DC Power Relay with Protection & De-Bounce. Screw Terminals. 120V Trigger Input. https://www.amazon.com/dp/B017743I7S/ref=cm_sw_r_cp_tai_UH9PCb8XDNSTH
The tl:dr if you have something that needs a relay (perhaps something that would otherwise be controlled by a thermostat as in my case) combinging this with the smart plug of your choice is the way to go.
I happen to be using it with a ARGO controller that’s connected to a Navian instant hot water heater that runs my heating.
(Basically I was too lazy to mess with sangoma relays and fortrezz was more expensive and I had plenty of ST compatible plugs :))
