One sample of each list on the Kaifa MA304H3E meter

(Samples are captured from my meter and the breakdown and values are from . Please note that units and/or data types in this document doesn't seem to be right. E.g. my total meter reading is 403 kWh, not the tenfold. Hopefully, the current is also closer to 1A than 1000A in each wire)

For the data parts, I have found they follow a pattern where the first byte dictates the data type and size: 02 - one byte following 06 - long (4 bytes / 32 bits) 09 - string, first byte is length
