The XTM35SC is an inexpensive current meter that can be purchased (e.g. on Amazon). It measures consumption, voltage and current on one phase. It does not require an external measuring ring. Suitable for home automation and smaller equipment. Of course, it is not MID compliant. The measurement results can also be queried remotely via Modbus RTU communication.
