Communication systems – smart metering
Whether water, heat, cold or electricity: modern energy measuring devices do not stand alone, but are integrated into complete system architectures.

With networked solutions and pioneering technologies, Sano  ensures optimal communication – and thereby creates the basis for simple and reliable reading, evaluation and billing of consumption data. The individual devices are integrated into strong networks via radio, M-Bus or LoRaWAN and the corresponding interfaces. Our own web solutions ensure easy consumption determination and lead intelligent smart metering, monitoring and optimization processes into the future.


Networking energy measuring devices simplifies the reading and evaluation of data. The Sano  product family offers fully integrable networking of heat, water, gas, electric meters and other devices with M-Bus protocol EN 1434-3. Tailored to different needs,


Wireless M-Bus is the radio version of the M-Bus standard.

Data encoding is done in the same way as for M-Bus, but the data is instead transferred via radio on the unlicensed frequency band (868 MHz in Europe). Wireless M-Bus is used for remote reading of, for example, meters for electricity, water, heat, and temperature. The supply of various M-Bus meters and equipment is very large, and because the communication protocol and the electrical interface are regulated by an EN standard, equipment from different manufacturers can easily be mixed into customized systems. 

The M-Bus standard defines how communication should work from the radio layer all the way up to including how the actual data is formatted. This means that all M-Bus compliant equipment works well together and that there is no extra product specific information required to interpret or operate M-Bus equipment from a protocol perspective.

Just like the classic M-Bus system, the wireless version also works according to a master-slave concept. A central unit, the so-called M-Bus master, controls numerous subordinate units, the slaves, which supply the master with data. This creates clear communication channels and dependencies between the individual actors within the infrastructure. A wireless M-Bus system can comprise several hundred slaves, which record specific sensor values, for example relating to energy consumption, but also to temperature and humidity.

The slaves send their collected data to the master at the frequencies 868 MHz and 434 MHz, without any cabling. Since the selected frequencies are license-free values, the license fees for data transmission are waived. When the wireless M-Bus master arrives, the data supplied by the slaves is collected, processed and made available to the operator for evaluation.


Sano integrates LoRaWAN as a new communication standard into its products, thereby making a technological leap in energy measurement. With your own web solutions, not only simple consumption determination but also intelligent smart metering, monitoring and optimization processes are possible. With LoRaWAN, IoT devices can be connected wirelessly over a distance of up to 15 km and brought to the Internet. Thanks to the long range within buildings, even measuring points in hard-to-reach places can be periodically reliably read and monitored remotely.

Sano has already integrated LoRaWAN technology into its products and, since 2019, has been offering, among other things, a new generation of compact heat meters, a new heat meter calculator and communication modules for house and apartment water meters.

Wireless data transmission via LoRaWAN/IoT (Internet of Things)
Transmission of measurement data at least daily
Early detection of equipment failures
Reports in the event of malfunctions and extreme consumption deviations from the norm
Can also be used for other IoT applications


NB-IoT is a standard radio technology that operates in the licensed frequency band and is designed to provide an optimal combination of range and energy efficiency.

Sontex radio

The compelling Sontex radio system allows flexible concepts for wireless data transmission in new and old buildings. Heat cost allocators, heat and water meters equipped with the most advanced radio modules send their consumption data to a radio data receiver or radio handheld terminal outside the rental property. Wireless transmission saves time and money and makes you independent.
