What should AMI buyers check before choosing DLMS smart meters?

A common mistake is to only ask:

Does this smart meter support DLMS?

A better question would be:

What DLMS objects, configuration files, services, security settings, and communication modules does this smart meter support in my AMI project?

Common DLMS/HES integration risks

AMI integration risks are usually not solely caused by smart meter hardware, but rather by unclear project requirements.

Common risks include:

HES is unable to read the required DLMS object

Undefined data object list before procurement

The firmware versions of different batches of electricity meters are inconsistent

The communication module does not match the on-site network

The data concentrator and smart meter have not undergone joint testing

The definition of safety requirements is too late

The requirements for load curve intervals and event logs are unclear

The acceptance standards of the power company have not been documented

Different suppliers have inconsistent understanding of the same DLMS requirement

HES compatibility and DLMS support scope should always be confirmed based on the selected meter model, firmware version, communication module, data object list, and project acceptance requirements.
