3. Shelly 3EM
The Shelly 3EM distinguishes and detects energy consumption and energy feed-in to the grid. The measurement data is displayed in the app, the optionally activatable cloud, and the web interface in clear graphics. Additionally, MQTT can be activated to register it with a corresponding MQTT broker. It is factory calibrated with the included clamps, achieving an accuracy of over 99%. 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.
Included in delivery: 1x Shelly 3EM, 1x user manual, 3x current transformers 120A.
4. Eltako Alternating current meter
Only calibrated meters are permitted for electricity billing according to § 25 of the German Calibration Act. Non-compliance is an administrative offense under § 19. Maximum current is 65 A, with a standby loss of only 0.4 watts. This is a modular device for mounting on a DIN-EN 60715 TH35 rail. 1 division unit = 18 mm wide, 58 mm deep. Accuracy class B (1%). Equipped with an S0 interface. This AC meter measures active energy based on the current flowing between the input and output. The self-consumption of only a maximum of 0.4 watts of active power is not measured or displayed. One external conductor can be connected with a current of up to 65 A. The starting current is 40 mA. If a load of more than 50% is expected, a ventilation distance of 1/2 division unit must be maintained from adjacent devices. If necessary, use the spacer DS12. Two N terminals for safe cross-wiring of multiple meters. The 7-segment LC display can also be shown twice within two weeks without power supply.

8. Orno Electricity meter
The device for measuring values in metric units (kWh) is designed for the direct measurement of active power in a three-phase system. A special electronics generates pulses under the influence of the flowing current and operating voltage, with the height of the pulses being proportional to the consumed electrical energy. The power consumption per phase is indicated by a flashing LED. The number of pulses is converted into consumed energy, and its value is displayed on the LCD screen (6+2). Power supply: 230 V~, 50 Hz, basic current: 5 A, maximum current: 80 A, minimum current: 0.25 A, pulse frequency: 800 imp/kWh, accuracy class B, three-module wide housing, mounting on DIN TH-35 mm rail, pulse output: power supply 12-27 V, pulse = 80 ms.
