Where is a Wired MBus system most useful?

It is ideal for use in multi-unit buildings where meters are installed close together and in environments where wireless communication is weak or unstable.

How many meters can I connect to a single MBus master?

A single MBus master can manage up to 250 meters. With repeaters and extensions, networks can support up to 1,250 meters.

Is a separate power supply required for each device?

No. Many meters can be powered directly through the MBus line, simplifying installation and reducing hardware requirements.

Can I combine wired and wireless meters in the same system?

Yes. ista supports hybrid networks that combine both wired and wireless MBus devices, giving you maximum flexibility.

How secure is the system against tampering?

Wired MBus systems allow for detailed monitoring of meter performance and can identify potential manipulation attempts or communication errors early.

No more signal loss and missed readings.

Wired MBus meters for accurate readings and reliable performance.

Our wired MBus technology provides stable communication and quick access to meter data. It also allows for seamless integration into existing building systems, making it ideal for multi-unit properties and locations with limited wireless connectivity.

No signal needed: Technology that just works.

Wired MBus is a tried-and-tested solution for energy and water metering, making it ideal for buildings where meters are close together or wireless connectivity is limited.

Using a physical bus connection enables rapid, interference-free data transmission and reduces system maintenance to a minimum. ista’s Wired MBus solutions help you to collect, analyse and act on consumption data with ease and confidence, whether you're managing a residential complex or a commercial site.

Reliable data transmission with the Wired MBus connectivity – Immune to interference, built to last

Each meter is connected to an MBus master unit via a dedicated cable. The master unit collects consumption data from all the connected meters and transmits it securely to your back-end system or reading system. As the meters are physically connected, data transmission is unaffected by environmental factors such as thick walls, signal interference or underground installations. Devices can be powered directly through the MBus line, which simplifies setup and extends the lifespan of battery-powered meters.

Collect data reliably in hard-to-reach areas

Wired MBus provides stable communication in meter rooms, basements and behind thick walls, without the need for a wireless signal.

Read hundreds of meters from one master

One MBus master can collect data from a distance of up to 250 metres, enabling fast, centralised readings with minimal infrastructure.

Minimize maintenance and service visits

Thanks to its hardwired, interference-free setup, the system runs reliably for years, reducing error rates and the need for on-site troubles

A technician is working in a narrow technical room or basement corridor under a ceiling with several parallel metal pipes. He is wearing a blue safety helmet and a work jacket and is raising both arms to check or adjust a pipe or bracket above him. On the right, further installations such as ventilation ducts and cable ducts can be seen, while the walls are made of concrete or brickwork. The perspective looks along the pipes into the depths of the room and emphasises the technical infrastructure of the building.

Reliable infrastructure. Ready to scale.

Wired MBus systems offer incredible flexibility in terms of installation. You can use linear, star or tree topologies – or any combination – to match your building's layout. A single master can manage up to 250 metres of cabling over nearly 3 kilometres, and extended networks can scale up to 1,250 metres and 14 kilometres. Thanks to the system's modular design, it can easily grow alongside your property portfolio while remaining compliant with European MBus standards.
