E-Spectro

E-Spectro is an IR probe designed for automated optical reading of electricity meters and other utility meters through IEC 62056-21, now also with support for the DLMS/COSEM protocol.

It is intended for apartment buildings, commercial sites, technical facilities, and energy projects where reliable remote meter reading is needed without manual on-site visits.

The sensor reads values such as 1.8.0, 1.8.1, 1.8.2, 2.8.0, 2.8.1, 2.8.2, 36.7, 32.7, 31.7, 33.7, and 14.7, giving a clear view of consumption, export, instantaneous power, current, voltage, power factor, and frequency.

E-Spectro can also monitor and synchronize time precisely, keeping interval data correctly aligned for evaluation, billing, and energy analytics.

Supported electricity meters include Landis+Gyr, Iskraemeco, ZPA, Siemens, ADD, and Apator, making it a flexible solution for diverse installations and straightforward integration into the Sensorly system.
