I'm thinking about buying a spare back-up TED, before the supply dries up..
At $20, these things aren't going to last forever.
I can't think of anything that fills this niche for $20.

For $20, these might be good for sticking on your hotwater heater..
Stand-alone-230vac logging meter?

I wonder if a resourceful DIYer could use these things for 120vac?
Maybe just multiply the displayed KW x two?
Or, put the clamps on the 120 lines, using a loop? (on each sensor clamp).

(Example of single loop).

That should double the amount of current read.. Transformer step-up effect.

I used 5 turns to boost sensitivity in my Sanyo current limiter (135A) sensors.
Those 5 turns, make 10A look like about 50A. Making it easier to adjust the setpoint to 10A..
