Best products in the Energy monitors category
Here's a ranking of the best products in this category. To give you a quick overview, we've also added some key information about the products.
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. 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.
3. 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.
4. Shelly Per 3EM
The Shelly Pro 3EM is a Wi-Fi powered, DIN-mountable 3-phase power meter with Wi-Fi, Bluetooth and LAN connectivity. With active energy measurement accuracy to within 1%, the Shelly Pro 3EM can be used to monitor the consumption of all household appliances, circuits and office equipment individually. Historical data is stored for up to 60 days, with each phase having a one-minute resolution. In addition, scripting capabilities allow the execution of complex scenarios and provide advanced monitoring capabilities.
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. Shelly EM WiFi Energy Meter
The Shelly EM WiFi energy meter monitors and measures the energy consumption in your home or office. Of course, the energy production of your solar system can also be measured. There is also a switching output that can be used to switch up to 2 A directly or optionally control a relay. Current transformers are not included in the scope of delivery.
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. BAT EM 231
The EM 231 energy cost meter helps you to save costs and energy. It measures voltage, frequency, current, power factor and power and thus calculates the total energy consumption incl. energy costs. 3 LR44 button cells are already included in the scope of delivery. This way, your data is stored safely even in the event of a power failure.
9. 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
