It's awesome!

I use one of these as a backup for an Alexa controlled hot water circulation system. Alexa actually sets the pump on time, and it's a backup that shuts off power to the pump in case Alexa goes nuts. They're so cheap I couldn't even buy a relay for that price. And they are already assembled! Why do I need 6? I do not know yet.

Pros
