Presumably the grill temp itself is best addressed through the grill—you can mechanically attenuate gas very effectively and intuitively, plus you'd presumably be at the grill already.

Personally I use charcoal because I like flavor. :)

I looked it up and this thing is actually for the thermometer, not the grill.

Points kinda the same tho right? Power strip is too early / dumb to modify a near-continuous variable on the device
