Furthermore, it features a relay contact that can be used to control a relay, for example. Installation is done in the distribution box on the DIN rail. The measurement values are displayed in real-time. It is also possible to calculate energy costs. The Shelly 3EM can be controlled via the Shelly app, the optionally activatable cloud, as well as through MQTT and REST API. Energy consumption thresholds can be set, and when reached, the Shelly 3EM can switch off the power via the relay contact. Control based on time or sunrise and sunset is also possible. In addition to measuring energy consumption, the energy fed into the grid can also be measured. The Shelly 3EM automatically detects how much energy is consumed and how much is fed in, presenting this information clearly in a graphic. The measurement data is stored in the cloud for 365 days. The data is also written to a CSV file in 5-minute intervals, which can be exported by the Shelly 3EM. The Shelly 3EM features a programming and debug header that can be used for flashing alternative firmware. It is equipped with an ESP8266 with 4 MB of flash. It can be integrated into various smart home systems: Home Assistant, Hubitat, openHAB, Domoticz, REST API, MQTT, ioBroker, nymea, and HomeSeer.

4. Shelly Pro 3EM 120A
The Shelly Pro 3EM is a Wi-Fi-operated, DIN-mountable 3-phase energy consumption meter with Wi-Fi, Bluetooth, and LAN connectivity. With its 1% accurate active energy measurement, the Shelly Pro 3EM can be used to monitor the consumption of all household appliances, circuits, and office devices individually. Historical data is stored for up to 60 days, with each phase having a one-minute resolution. Additionally, the scripting functionalities allow for the execution of complex scenarios and provide advanced monitoring options.
Includes 3 current transformers 120 A.

5. Voltcraft SEM6000 CH
Elegant design meets top precision. The VOLTCRAFT SEM6000 CH BT energy cost meter offers the perfect compromise between design and functionality. Hidden within the compact 55 by 55 millimeter pure white housing of the SEM6000 CH is high-quality measurement technology that accurately measures power consumption and power factor to three decimal places.
Current energy consumption at a glance: Thanks to the simple LED ring, seamlessly integrated into the housing, you can easily see the current energy demand of the connected device. The color of the LED ring ranges from deep green to red, changing according to energy consumption. Green indicates low consumption, while red signals high energy demand.
Consumption analysis in your preferred file format: You can easily and conveniently convert the energy consumption data into various Office and Google formats in the form of graphs. Whether you want to analyze days, weeks, months, or years, it’s all possible.
Your smartphone becomes a remote control: Turn the VOLTCRAFT SEM6000 CH on and off effortlessly using your smartphone or tablet. This way, it not only serves as an energy cost meter but also transforms your device into a remote control.
Automated switching of connected devices: Do you want your lighting to automatically turn on at 8 PM and off again at 6 AM? No problem. Program the switching times conveniently through your smartphone or tablet. You can program a total of 12 switching times (either on or off) for the SEM6000 CH. Each switching time can be set as a one-time event or with repetition (selecting the weekdays on which the switching time will repeat).
Special features: Bluetooth interface, data export, data logger function, cost forecast, adjustable electricity tariff, app control.

6. Shelly PM Mini Gen3
Shelly PM Mini Gen3 is a smart power meter with a compact design that enables remote monitoring of the electricity consumption of electrical devices. It can be retrofitted into standard flush-mounted boxes, behind sockets and light switches, or in other locations with limited space. The device can be accessed from anywhere the user has an internet connection. It can be controlled and monitored as long as it is connected to a Wi-Fi router and the internet. The device features an integrated web interface that allows you to monitor, control, and adjust its settings. 1 piece.

7. Max Hauri Energy meter 220-240V max. 2300W
Energy measuring device. Voltage: 220-240V. Power: max 2300W. Additional feature: enhanced touch protection. This energy measuring device is designed to measure the energy consumption of the connected appliance and calculate the resulting electricity costs. The electricity price is freely programmable. Important additional data such as power, voltage, current, power factor, frequency, and operating time can be easily accessed. An ideal device for implementing targeted energy-saving measures.

8. Eltako Alternating current meter
Energy consumption display with screen - smart metering for DIN rail. Standby loss is only 0.5 watts. The energy consumption display measures 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 compliance declaration in Europe, it is not approved for monetary electricity billing. The accuracy corresponds to that of all Eltako AC meters of class B according to MID (1%), with a starting current of 20 mA. This allows the energy consumption display to accurately replicate the measurement of the meter installed elsewhere in the building for electricity billing. The display screen is divided into three fields. Total reset: To start storing the values with hourly precision, a total reset is recommended at a convenient time after installation. To do this, press and hold the Mode and Select buttons simultaneously for 5 seconds until RES appears in field 1.

9. Check
Find the energy guzzlers in the office, home, hobby room, and civil protection cellar. With this practical device, you can accurately measure how much electricity an appliance consumes. The energy consumption is displayed in kWh with three decimal places of precision. Other measurements are also easily possible, such as conversion to costs, voltage, and network frequency.
