Hello,
I am working with a smart energy meter using Gurux.
I successfully connected to the meter using the optical interface (IEC 62056-21) and was able to:
Read meter data Zpa am165
Read the meter name/identification
I then tried to connect using the Ethernet (HAN) port with:
Laptop → USB-to-Ethernet adapter
Direct Ethernet cable to the meter
No router in between
The Ethernet link does not come up (Windows shows network cable unplugged,)
Hi, IEC 62056-21 is not DLMS…
Hi,
IEC 62056-21 is not DLMS. https://gurux.fi/DLMSCOSEMFAQ
Check first is the HAN Ethernet port. It's usually the serial port.
