Off-hand I'd think for things like a grill I'd want this to be handled at the power strip level. Normally a grill, like a weber grill, is just a piece of metal and will last until you wear it out (even then it's mostly the flimsy legs that fail). If you add internet connectivity, the expected lifetime value of a product goes way down: failing hardware, services that get shut down, protocols that stop working as expected.
Meanwhile at the power strip level, you can both monitor and enforce energy usage, something that's beneficial even if you remove the ability to control it remotely (and why would you!?). I'd imagine for most things but maybe my computer and media setup I'd prefer to be able to simply cut the power to ensure it's not running.
EDIT: Apparently this is a meat thermometer!
Not even being picky and sticking with an open protocol like ptpp but any kind of internet controllable power strip. All I can find are single outlets at ~$25 a piece.
It plays nicely with Home Assistant. https://www.kasasmart.com/us/products/smart-plugs/kasa-smart...

Fairly expensive though.
Valid concern about more moving parts and expected lifetime
Personally I use charcoal because I like flavor. :)
Points kinda the same tho right? Power strip is too early / dumb to modify a near-continuous variable on the device
