  * Janitza B23: These meters have a higher update rate than the Eastron
  devices, but they are more expensive.
+ * DZG DVH4013: This meter does not provide raw phase power measurements
+ and only aggregated import/export measurements. The meter is only
+ partially implemented and not recommended. If you want to use it: By
+ default, the meter communicates using 9600 8E1 (comset 5). The meter ID
+ is derived from the serial number: take the last two numbers of the
+ serial number (top right of the device), e.g. 23, and add one (24).
+ Assume this is a hexadecimal number and convert it to decimal (36). Use
+ this as the meter ID.
