Link to extension cords?
It is definitely on my to-buy list at some point later this year. I am sometimes away from home for days at a time, and always sweat a cable modem or router lockup cutting off my remote home control when I'm a thousand miles from home. I would buy one just for the auto-ping power-cycle function of the network stuff, and link it to HE for additional HA monitoring/control of the outlets.....

I didn't shop/research (it was a suggested purchase when I added the strip to my cart), but they appear to be UL certified and use a heavier cable per the reviews.....
I have two of these. Not on HE, but on their own app.

This helps greatly when dealing with power bricks
Mine came today. Thx. Heck of a find, I’m ordering another
Got mine yesterday, and paired it up today with no issues. Think I'm ordering 3-4 more this afternoon, if for no other reason than they are almost as cheap as "dumb" power strips. Thanks for the pointer @Rxich, and also Nick Veenstra for writing the device support!
