Power Plus Communications AG (PPC) and peerMetering have ensured the compatibility of their products for wireless 1:n connectivity. This allows distributed meters in multi-family residential buildings to be connected wirelessly via a PPC smart meter gateway.
Mannheim/Osnabrück, November 9, 2026 – Metering operators can now use peerMetering’s communication solution with PPC’s smart meter gateways. Data is transmitted to the gateway via the wM-Bus Compact Profile. wM-Bus is the established communication standard between meters and smart meter gateways. Therefore, no separate integration is required.
How the wireless 1:n connection works
Each meter is equipped with a transmitter module. It records the meter readings and transmits them wirelessly to the central receiver. The receiver makes the meter readings available to the smart meter gateway via wM-Bus. After the gateway administrator has configured the standard settings, the gateway can receive the data. A receiver module aggregates the meter readings from multiple meters for a single gateway.
This solution eliminates the need for additional data cabling between the meters and the gateway. This simplifies installation in multi-family buildings, especially when meters are spread across multiple floors and the range of conventional wM-Bus devices is no longer sufficient. Metering operators can thus use the existing SMGW infrastructure for the 1:n connection and efficiently implement the iMSys rollout in apartment buildings with complex installation scenarios.
Karen Schmid, Team Leader of SMGW Product Management at PPC, also confirms this: “Interoperability via wM-Bus is crucial for metering operators to scale the rollout cost-effectively for multi-family residential buildings. It is therefore very important to us that our smart meter gateways can be used with different meter solutions.”
PPC offers the peerMetering solution as part of PPC connect as an interoperable metering solution. The wireless connection between the transmitter modules and the receiver is encrypted using AES-128. For transmission from the receiver module to the smart meter gateway, peerMetering uses the OMS-wM-Bus standard. Each communication adapter has a PTB type approval certificate for use in metrology-compliant metering operations and meets the requirements of the BSI’s Technical Guideline TR-03109. A product extension for compatibility with eHZ and base meters is currently undergoing the certification process.
Already in use by metering point operators
Both incumbent and competitive metering point operators are already using the peerMetering solution in production; several thousand devices have been delivered to date.
Jan-Frederic Graen, CEO of peerMetering, summarizes: “The smart meter rollout must also work simply, quickly, and cost-effectively in apartment buildings. This is exactly where our 1:n solution comes in: We enable the wireless connection of multiple electricity meters to a shared smart meter gateway—without the need for additional data cabling. Compatibility with PPC’s gateways is another important step toward establishing this technology across the entire market.”
