I use a BLI power meter monitor, but I went a different route. I should have just bought the WiFi adapter, but I wanted a project. So, I use an Arduino to decode the 433MHz signal, decode it, and send the data to HG via MQTT. I also use the Arduino to decode an Acurite 5in1 weather station and an Acurite 592TX temperature sensor.
It works ok, but range is an issue that a new hardware setup will hopefully correct.
