Where to buy Iotawatt these days?

only gives me the option for the 120V kit, which has way more than I need.

I’m looking for a 2nd Iotawatt to monitor my sub-board. I thought I could do it with shelly but they go into overpower mode as soon as the load is over 10A (despite being advertised as 16A rated).

TIA
