FRITZ! Smart Energy 250 Trådløs hjemmesender Vægmontering RF Wireless

The AVM Smart Energy 250 RF Wireless Alkaline Battery wall-mounted transmitter is a compact device designed for smart home energy management. It provides wireless RF communication from a fixed wall position and is powered by standard alkaline AA batteries. With a slim profile and unobtrusive design, it integrates into domestic environments to relay energy-related signals and control information to compatible smart home systems.

Advantages

The transmitter delivers reliable RF connectivity for local smart home networks while avoiding hardwired installation, relying instead on replaceable AA alkaline batteries for power. Its compact dimensions (33.7 mm width, 36.4 mm depth, 76.5 mm height) allow straightforward wall mounting in corridors, utility rooms, or adjacent to energy meters. The battery-powered operation makes placement flexible and reduces installation complexity compared with mains-powered alternatives. The device is designed for consistent signal transmission in typical residential settings and supports integration into broader energy management workflows.

Suitable for

• Wireless transmission of energy data and control signals in home automation systems
• Installation near utility meters, distribution boards, or appliance clusters for monitoring
• Retrofit projects where running power lines is impractical
• Temporary or permanent placements that require a compact wall-mounted transmitter

How to use

Mount the transmitter on a suitable vertical surface using compatible screws or mounting hardware and insert the required alkaline AA batteries following the polarity markings. Position the unit within range of the receiving hub or gateway and follow the hub's pairing procedure to register the transmitter on the smart home network. Place the device near the monitored energy source or in a location that provides clear RF path to the gateway. Replace batteries as needed to maintain consistent operation and verify pairing status through the connected system's interface.

Recommendations

For optimal performance, install the transmitter at a height and location with minimal obstructions between it and the receiver; avoid placing it behind large metal objects or inside closed metal cabinets. Use high-quality alkaline AA cells and check battery contacts for corrosion during periodic maintenance. Confirm RF compatibility and range with the target smart home gateway before final installation.
