Eastron SDM630 Emulation

Below the registers with the Eastron SDM630 emulation firmware. More Eastron kWh meters using the same register configuration. This setup could be used in more configurations.

Default settings

The default dongle settings are:

9600 baud 8N1 ... modbus address 2

Register values are available in FC04, all float 32 IEEE 754.

No value = 0, for example when U2 isn't available (single phase system) this value is 0.

Be aware

There are several smart meter version in the EU. In The Netherlands version 2/4/5 are widely used. Some data isn't available in older version. Eg. voltage isn't available in v 2 and 4 smr versions. For some solutions this could be an issue.
