1. Steffen digital brilliant

Ideal for indoor use; Displays watt, ampere, volt, hertz, cosine φ or kilowatt hours; With overload protection; Two tariffs adjustable; With large LCD display. The energy meter shows you the voltage, frequency, current and power values in real time and works with all the electrical appliances in your household. 

2. Brennenstuhl Primera-Line PM 231 E

Helps to save costs and energy. Measurement of voltage, frequency, current, power factor and power. Calculation of total energy consumption and energy costs. Display of the measuring time in hours and minutes. 2 individually adjustable electricity tariffs (day + night). Includes 3 batteries LR44 for data storage in case of power failure. Socket outlet with child protection. 

3. Shelly 3EM

The Shelly 3EM distinguishes and detects energy purchase and energy feed into the grid. The measured data is displayed in the app, the optionally activatable cloud and the web interface in clearly arranged graphics. Additionally MQTT can be activated to register it at a corresponding MQTT-Brocker. It is calibrated in the factory together with the supplied clamps to achieve an accuracy of over 99%. In addition, it has a switching contact which can be used to control a relay, for example. It is installed in the fuse box on the DIN rail. The measured values are displayed in real time. It is also possible to calculate the energy costs.
The Shelly 3EM can be controlled via the Shelly App, the optional actuatable Cloud but also via MQTT and REST API. It is possible to set energy consumption thresholds. When these thresholds are reached, the Shelly 3EM will switch off the power via the relay contact. It is also possible to control by time of day or by sunrise and sunset. In addition to measuring energy consumption, the energy fed into the grid can also be measured. The Shelly 3EM automatically recognizes how much energy was drawn and how much was fed in and displays this clearly in a graphic. The measurement data is stored in the cloud for 365 days. The data is also written to a CSV file at 5 minute intervals, which can be exported by the Shelly 3EM. The Shelly 3EM has a programming and debug header that can be used to flash alternative firmware. Built in is an ESP8266 with 4 MB flash. It can be integrated into various smart home systems: Home Assistant, Hubitat, openHAB, Domoticz, REST API, MQTTT, ioBroker, nymea and HomeSeer.

4. Voltcraft Digital three-phase meter

Digital three-phase meter for DIN-rail mounting in sub-distribution boards. The meter enables direct current measurement up to 100 A/phase. The energy meter is intended for installation in control cabinets or sub-distribution boards with 35 mm DIN rail mounting as an indoor meter. The energy meter enables the display of the consumed active energy in three-phase 4-wire power systems with a reference current of 10 A (limit current 100 A). The energy consumption is displayed cumulatively in kilowatts per hour (kWh) for all three outer conductors. An LED display for each outer conductor enables the control of a symmetrical load 

5. Qubino 3-phase Smart Meter

Reduce energy consumption. Qubino's 3-Phase Smart Meter allows you to remotely measure the energy consumption of your home. It is the only 3-phase energy meter on the market through which electricity flows. No current clamps required. It measures 9 different values: V, A, W, var, PF, kWh import, kWh export, kVAh, kvarh. By adding additional IKA or BICOM contactors, the Qubino 3-Phase Smart Meter can automatically turn off devices that exceed the set power consumption. For example, the heating switches off automatically when the set power consumption value is reached. 

6. Max Hauri EMR-1

Energy meter EMR-1 / voltage: 220-240V / power: max. 2300W / batteries: 3x 1.5V LR44 / additional function: child protection.

7. Check

Find the power guzzlers in the office, household, hobby room and civil defence cellar. With this handy device you can measure exactly how much power a device consumes. The energy consumption is displayed in kWh to three decimal places. Other measured values are also possible without problems, such as conversion into costs, voltage and mains frequency. 

8. Eltako Alternating current meter

Energy consumption indicator with display - smart metering for mounting rail. Stand-by loss only 0.5 Watt. The energy consumption display measures the active energy like an AC meter based on the current flowing between the input and output and stores the consumption in non-volatile memory. Like all meters without MID declaration of conformity, not approved for monetary electricity billing in Europe. As with all Eltako AC meters, the accuracy corresponds to class B at MID (1%), the starting current is 20mA. Thus the energy consumption display exactly reproduces the measurement of the meter installed elsewhere in the building for electricity billing. The display is divided into 3 fields. Total reset: In order to start saving the values accurately to the hour, it is recommended to perform a total reset at a convenient time after installation. To do this, press the MODE and SELECT buttons simultaneously for 5 seconds until RES appears in field 1. If SELECT is now briefly pressed. 

9. Smappee Infinity Starter Kit

Interfaces: RJ-45 (Ethernet), Functions: Energy cost calculation, Connection: 3-phase, Data provider: Trustbox.

10. Carlo Gavazzi Energy meter EM24

Carlo Gavazzi three-phase energy meter EM24 DIN direct measurement.
