Regarding the kits.
IoTaWatt Kit 230V consists (among other things) of:
- Mains Current Sensor (1 x 100A)
- (3) 100A Split-core current transformers for Mains or branch circuits
Are those 4 devices of 2 different types (current sensor, current transformer) or are those 4 devices of exactly the same type and only the name might be misleading for a newbie?
