3-Phase Meter Telstar CT - Current Transformer Version
The smart-me Telstar CT is an MID-certified energy meter with integrated WiFi interface for the transmission of real-time data and with connection for external converters. The meter synchronises the measured values automatically and encrypted in the smart-me cloud. The measured data can be exported to various third-party systems and processed further via various interfaces.
Functions
Inputs for external current transformers from 0.01 to 6A output
Encrypted real-time data connection to the intelligent smart-me cloud
Remote switches, time switches and condition-based switches via the outputs
Comprehensive energy data management and visualisation, automatic billing as well as intelligent control and alarms using the smart-me cloud
Floating contact outputs for controlling external devices (one of them with an integrated 8A relay)
Floating contact input for tariff signal or digital input
Easy installation with the free smart-me app for Android and iOS
Interface to a variety of third-party systems such as billing and building management systems as well as smart home systems (via API, CSV, MSCONS, IS-E or Modbus TCP)

Display
The counter has a rolling display. The items described below are displayed one after the other. After the last point, it starts again at point 1:
Meter reading (OBIS code followed by meter reading)
1.8.1 (A +) Active energy import tariff 1
1.8.2 (A +) Active energy import tariff 2
2.8.1 (A-) active energy delivery tariff 1
2.8.2 (A-) active energy delivery tariff 2
1.8.0: 5A (A +) active energy total import 5A basis
2.8.0: 5A (A-) active energy total delivery 5A basis
5.8.0 (Q1) Inductive reactive energy import total
6.8.0 (Q2) Total capacitive reactive energy import
7.8.0 (Q3) Total inductive reactive energy delivery
8.8.0 (Q4) Total capacitive reactive energy delivery

Measurements and Wiring

Wiring diagram
T1 button for installation
T2 special functions
In short: If T2 is pressed> 2s, the green LED lamp switches on / off. If this is activated, it shows the connection status
Glowing green: connected to smart-me cloud
Flashing green: connection is currently established, at the moment no connection
Long: If T2 is pressed> 8s, the display of the power is switched between active and reactive power. In addition, the calibration pulse LED alternates between active energy and reactive energy.
Very long: If T2 is pressed> 14s, the S0-0 pulse output is switched between active power and reactive power.
ATTENTION: This setting only changes the display, not in the smart-me cloud (app and website). If the reactive energy is to be displayed in the cloud, this must be done in the general settings.
