  2. 6-digit Field Values From Meter Not Fully Received (only 5 Digits Shown)

6-digit field values from meter not fully received (only 5 digits shown)

Hello Gurux Team,

We are currently facing an issue while reading meter data using Gurux DLMS libraries.

In the field, some meters are configured to return values with 6 digits (for example, energy or billing-related parameters). However, while reading these values through Gurux, we are consistently receiving only 5 digits, even though the meter display shows 6 digits.

Observations:

The meter display clearly shows a 6-digit value.

Gurux response contains only 5 digits for the same OBIS/field.

This issue is seen only for specific meters/configurations.

No explicit parsing or scaling logic is truncating the value on our side.

Queries:

Is there any known limitation or configuration in Gurux that could cause truncation of digit length?

Could this be related to scaler/unit handling or data type interpretation?

Are there any meter-specific settings or DLMS attributes we should verify to correctly fetch all 6 digits?

Please let us know if any additional logs, OBIS codes, or sample responses are required from our side.

Thanks in advance for your support.

Regards,
Bhanu

Adding one more…

Adding one more clarification: This issue is observed specifically for kWh values.
The meter display shows a 6-digit kWh value, but the value received via Gurux DLMS contains only 5 digits for the same kWh OBIS code.

Hi Bhanu, The meter display…

Hi Bhanu,

The meter display can show different values that the meter returns.

The meter value is multiplied by the scaler and shown as it is.

Check first what the scaler value is.

BR,
Mikko
