Oh yeah, as a hobby, it’s absolutely fun. I like tinkering with all kinds of things.

My point was to just be careful since it’s not necessarily going to be worth the expense and time.

I’ve been considering getting a breaker-level power monitor to watch for spikes. It’s a bit more expensive (hundreds of dollars), but it measures the types of things I’m interested in. My kid flipped on our gutter heaters (I never use them) and shot our electricity bill to the moon for a couple months until I noticed. If I had a home energy monitor, I would’ve noticed a crazy energy spike and that might have paid for itself.
