EMS Prime Switch

The Missing Link of Smart Surplus Energy Management in the Fibaro Ecosystem.

Is your smart home truly optimizing energy costs, or just passively watching them?

If you own a photovoltaic system integrated with a Fibaro HC3 gateway, you are likely feeding valuable energy back into the grid for pennies every single day. Even worse—unthoughtful automations that switch on your devices, such as water heaters or heat pumps, during passing clouds can damage their expensive electronics due to relay chattering.

ICAS EMS Prime Switch changes the game. It is an advanced QuickApp that empowers the Fibaro ecosystem with missing decision-making algorithms, turning passive monitoring into a maintenance-free, cascading cost-saving engine.

Experience the difference within the first minutes of installation

Installation is as simple as downloading the file, importing it into your Fibaro HC3, and assigning the ID of the controlled device. Zero LUA scripts, zero frustration—the app instantly guides you through a straightforward setup and calibration. Once you open the panel in your Fibaro system, you get a clean control hub that gives you complete command over your energy management:

Dynamic power balance monitoring

Track real energy flows across your entire installation live. In real time, the system analyzes solar production, current home consumption, and the precise level of energy surplus or grid import.

Complete overview of status and operational parameters

Monitor the current state of your managed device along with its operating mode all in one place. Additionally, continuously preview key decision-making rules: calculated required power, configured surplus coverage thresholds, stabilized delay timers, and minimum runtime settings.

Energy surplus management panel

See at a glance which turn-on conditions are currently met, the remaining time before launch after surplus stabilization, and the guaranteed operating cycle duration that protects your equipment from wear. If other EMS Prime Switch instances are detected on your Fibaro gateway, the system automatically transitions from standalone (Single-Mode) to shared operation (Multi-Mode). It visually displays how energy is balanced between devices across the network based on assigned priorities and available surplus—completely transparently.

Single-Mode

Multi-Mode

Precise self-consumption analytics and real savings

The application automatically measures free solar kilowatt-hours retained in your home and converts them in real time into estimated financial savings. Energy statistics are neatly categorized and reset across daily, weekly, monthly, and annual cycles, allowing you to see the exact money kept in your pocket at any time.

Flexible operating mode control

The default mode is full automation (Auto) powered by EMS Prime Switch’s intelligent algorithms. However, at any moment, you can force manual operation (Run) or completely lock out the device (Lock) while away on vacation or during routine maintenance.

Why is this QuickApp essential for your Smart Home?

A True Smart Home

Your automation finally fully utilizes the data gathered by Fibaro HC3. Stop just viewing solar energy statistics and start actively taking advantage of surplus power to generate real financial savings.

Advanced Equipment Protection

The app actively safeguards your appliances. Minimum surplus stabilization delay and minimum runtime parameters effectively protect relays and compressors from rapid switching cycles.

Precise Partial Coverage

You decide what percentage of the device’s power must come from the sun. The app can switch on a load at e.g., 60% solar coverage, purchasing only the absolute minimum required balance from the grid.

Custom Logic Conditions

Combine energy surplus rules with any Fibaro sensor. Triggering a water heater only when surplus is available AND water temperature is below 55°C takes just one simple rule setup.

Advanced Cascading Control (Multi-Mode)

Multiple QuickApp instances seamlessly collaborate. Surplus power is allocated first to the highest-priority device (e.g., heat pump), and remaining excess automatically powers subsequent loads (e.g., EV charger or water heater).

Native Fibaro Experience

Full visual integration with an interface that automatically detects 24 languages, location previews within your home structure, and PUSH notifications alerting you when running on free solar power.

Comprehensive Configuration Options

The initial installation launches the system with optimal default settings, allowing you to evaluate the full potential of the algorithm right out of the box. At any time, you can fine-tune most parameters to meet your specific needs. Full parameter descriptions and step-by-step guides can be found on our product page.
