How about an ACS758 based AC/DC current sensor board
So the ACS758 current sensor has some great capabilities in a pretty small package (see https://www.digikey.com/catalog/en/partgroup/acs758/10579), and boards like https://www.amazon.com/50A-Current-Sensor-AC-DC/dp/B0187AAOMS are great, but something slightly smaller (remove some extraneous connectors and pads?) and hopefully cheaper ($8-9 each??) would be very useful, especially if we want to create our own monitored power strips to take charge of how much power is used by our devices.
It's also very easy to read from an Arduino or RPi or other similar micro (see http://henrysbench.capnfatz.com/henrys-bench/arduino-current-measurements/acs758-arduino-current-sensor-tutorial/). I think it'd round out your sensors quite well, and while you do have non-invasive split core AC measuring, it's on the bulkier side compared to a small board like this which is to be permanently integrated into the circuit, unlike the split core design.
