3-Phase Meter

Versions

• Direct measurement up to 80 A (not switchable)

• Direct measurement up to 32 A (switchable)

Functions

• 3-phase energy meter with MID 2014/32/EU certification

• Direct measurement up to 80 A (not switchable), direct measurement up to 32 A (switchable)

• Real-time measurement data with maximum precision, class B

• Additional contact output to control external devices

• The 3-phase meter acts as a gateway to the cloud for (almost) all IP-capable smart-energy devices  like heat pumps, heating systems, battery storages, and many more

• Easy installation using the free smart-me app available for Android and iOS

• Encrypted Wi-Fi connection directly to the smart-me cloud. The smart-me cloud offers a comprehensive energy management system, including visualisations, if/then actions, automated billing, and interfaces to third systems (Auto Export / API)

Installation

Before you can use your smart-me device, you have to connect it to your Wi-Fi network.

1. Connect your smartphone or tablet to the WLAN.

2. Download and install the free smart-me app from the App store on Android or iOS.

3. Start the app and create a free accoun or login into an existing relevant account.

4. Click on “Add Device” (+) and follow the instructions.

Configuring inputs and outputs

The smart-me meter has two outputs and one input, which can be used as pulse inputs and outputs or as a switchable potential-free contact.

Display

1. Display sequence

The meter has a rolling display. The bullet points summarized below are shown sequentially. After the last value, the sequence starts anew.

1.) Phase order (if incorrect, see below)

2.) Counter reading (Obis code followed by counter reading)

1-8-1: active energy tariff 1

1-8-2: active energy tariff 2

3-8-1: reactive energy tariff 1 (if available)

3-8-2: reactive energy tariff 2 (if available)

3.) Software version

4.) CRC value

Phase order

PhL 1 -> only phase L1 has been connected (PhL2 for L2 etc.) 

PhL12 -> only phases L1 and L2 have been connected (PHL13 for L1 and L3 etc.) 

PhL123 -> a wrong phase order has been detected.
