3-Phase Meter Telstar 80A
The smart-me Telstar 80A is a MID-certified energy meter with an integrated WiFi interface for transmitting real-time data. The meter synchronises the measured values automatically and encrypted to the smart-me Cloud. The data can be exported and further processed in the smart-me Portal or via our open interface in third-party systems. The meter has two digital outputs for controlling potential-free devices.

Button functions

T1 Button for installation
If button T1 is pressed for 10 seconds, a local WiFi is created for the installation
T1 + T2 Restart
Press buttons T1 and T2 simultaneously for 10 seconds to force a restart.
T2 Special functions
Short: If T2 is pressed >2s, the green LED toggles (from off to on or from on to off). When activated, it indicates the connection status
🟢 Green steady: connected to the smart-me Cloud
❇️ Green flashing: establishing connection or no connection
Long: If T2 is pressed >8s, the power display toggles between active and reactive power. In addition, the calibration pulse LED switches between active energy and reactive energy.
Very long: If T2 is pressed >14s, the S0-0 pulse output toggles between active power and reactive power.
Note: This setting only changes what is shown on the display, not in the smart-me Cloud (app and website). If reactive energy is to be displayed in the Cloud, this must be done in the general settings (allgemeine Einstellungen).
LED

🟢 Green LED - connection status
- Shows the status of the connection to the smart-me Cloud. a) Flashing = connection error b) Always on = connection OK

🔴 Red LED - pulse LED
-
Shows the currently consumed active or reactive power in 1000 pulses/kWh or 1000 pulses/kVArh. Whether active or reactive power is displayed can be set with button T2.
-
For example: An LED labelled "1000 pulses/kWh" flashes 1000 times when 1 kilowatt hour (kWh) of energy has been consumed or delivered. If the 1000 pulses were counted within 1 hour, a constant power of 1 kW was measured.
Configuring inputs and outputs
The Telstar 80A has two digital outputs and one digital input, which can be used as pulse inputs and outputs or as a switchable potential-free contact. You can find details on the wiki page Input and Output Configuration
The Telstar 80A has a relay on one digital output that can switch up to 8A.
Mesh technology
If WiFi reception is very weak or absent, the Telstar 80A automatically connects via the mesh function to another neighbouring meter within range. This meter then takes over communication with the smart-me Cloud. Mesh technology ensures that the meters have higher availability towards the smart-me Cloud. It is not possible to deactivate the mesh function on the meter. Specific restrictions apply when Modbus TCP is activated.

FAQ
At what interval do the meters send data?
-
Every 15 minutes, i.e. at xx:00:00, xx:15:00, xx:30:00 and xx:45:00. This sends the data required for the load profile. In the event of a connection interruption, this data is stored locally and sent later.
-
In addition, at least every 330 seconds.
-
Furthermore, when one of the following events occurs:
-
Meter reading change greater than 100Wh
-
Power change greater than 100W
-
Current change greater than 1A
-
Voltage change greater than 1V
-
Every second when the meter is selected in the GUI (smart-me Portal)
-
Can I reset the meter reading to zero?
No, since our meters are used for billing, it is not possible to reset them.
