6. 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.

9. my-PV Three-phase energy meter
3-phase measuring transformer for my-PV devices. Clamp current transformer for the simplest measurement capture and high installation comfort. Also suitable for large connection capacities in commercial applications. Wireless communication via WLAN. Measurement range: 0 - 75 A (higher currents can be measured with optional clamp transformers). Protection class: IP51. Dimensions: 90.2 x 71 x 57.5 mm. The my-PV Wifi Meter analyzes the current flows of the PV system. It transmits information about surplus power to the router via WLAN. This ensures that only the energy available at the moment is used for heat generation. Therefore, there is no feeding into the power grid: self-consumption of the PV system is maximized, relieving the public low-voltage network. The my-PV Wifi Meter is installed directly after the energy supplier's meter in the distribution cabinet and measures the load flow through three external clamp current transformers. The my-PV WiFi Meter comes standard with integrated 75 A current transformers. The new my-PV WiFi Meter no longer requires an Ethernet cable (LAN) and can be integrated into the home network via WLAN. This offers the advantage that connections from the meter cabinet to the router can now be established wirelessly. To ensure that signals from the meter cabinet, which is usually made of metal, can be transmitted and reach the desired target, an antenna with a 1 m cable is also included as standard. The functionality and view in the my-PV.LIVE Cloud remain the same as with the previous my-PV Power Meter. This offers the advantage that the transition for the customer is barely noticeable. We also see the new my-PV WiFi Meter as a guardian of the current flows of the photovoltaic system, ensuring everything runs optimally.
