Monitor and discover real-time data of your SMA solar photovoltaic plant or locate secret power wasters in your home. Individual SMA sensors or inverters can be examined directly (see below list of supported devices). The app communicates locally with the solar system without a cloud. This means that real-time measured data are available at lightning speed and changes of power values are detected immediately. Discover and explore your photovoltaic system and keep track of your power grid! Connect your iPhone or iPad to the same network (WiFi) as your PV plant and get a deep insight of your power grid. The app works best with self-consumption plants (plants with Sunny Home Manager devices). The focus of the app is to monitor real-time data values. Long-term recordings are currently not possible (apart from the grid consumption measurements). ** Features ** * Monitor SMA Energy Meter real-time data * Supports SMA inverters (via MODBUS protocol only!) * Automatically finds and detects SMA devices and sensors on the local network * Energy flow display of your solar plant (self-consumption plant) at the grid connection point * Measurement of consumption values (grid consumption measurement) * Separate view of individual phases (L1, L2, L3) via Energy Meter sensors * Collecting values into charts * Detailed measured value view for each individual SMA device/sensor * Use the app to detect und jump onto the web interface of the inverter device ** Supported SMA Sensors and Inverters ** * SMA Energy Meter 1.0 + 2.0 (via Speedwire protocol) * SMA Sunny Home Manager 2.0 (supports only the build-in Energy Meter!) * SMA Sunny Boy Storage 3.7, 3.8, 5.0, 6.0 (via MODBUS) * SMA Sunny Island Storage 3.0, 4.4, 6.0, 8.0 (via MODBUS) * SMA Sunny Tripower 8.0 - 10.0 (via MODBUS) * SMA Sunny Tripower Smart Energy (Hybrid, via MODBUS) ** NOT supported devices ** * SMA Sunny Home Manager 1.0 (HM-10) Hint: Manual activation of the MODBUS protocol is required for communication with SMA inverters in the device settings. For this you need installer rights of your inverters! We are looking forward to your feedback or questions to feedback@heiko-pruessing.de!

Charge your electric car when the sun is shining or when electricity is clean and affordable. With this app, you can access your local evcc instance on your home network. App Features: - Automatic detection of your evcc server - Interaction with your evcc UI - Demo instance available for testing - Light/Dark Mode: Adapts to your device Prerequisite: You must have evcc installed on a device (Raspberry Pi, Windows, macOS, Linux Docker, ...) at your home. What is evcc? evcc is an open-source software that runs at your home. It is compatible with many PV and battery systems and controls your EV charger - regardless of manufacturer. If your car has an online interface, you can also use smart controls like charging schedules, minimum charging, and charging limits. Additionally, it supports dynamic electricity tariffs, smart plugs, balcony solar systems, and small home batteries.

Verdict
The clearest difference is price: evcc.io at Free against Energy Meter's $3.99. evcc.io also leads on update cadence (every 2 months vs every 6 months). On review sentiment, ads, in-app purchases and device support there is nothing between them.
