wM-Bus RF handheld receiver
NVS RF Terminal
Wireless meters broadcast their telegram on their own; the job is to catch it. The RF terminal plugs into a computer and collects the telegram of every meter that comes into range as you walk the floors. The reading finishes without entering a single flat or disturbing anyone.

What it does
Read without entering the flat
Even when the meter sits inside the flat, the telegram reaches outside. Appointments, knocking on doors and empty flats stop being a problem.
Collect while walking
The terminal accumulates every telegram that comes into range. Walking the floors is enough to finish a whole block.
Decodes encrypted telegrams
If the meter broadcasts with an AES key, the key is registered and the telegram is decoded and read.
Doubles as a coverage survey
Before installing a permanent RF collector, measure which meters are heard from which point — so the collector goes in the right place.
Suited to
- Periodic reading of wireless meters that broadcast wM-Bus
- Coverage survey before installing a permanent collector
- Reading in buildings where flats cannot be entered
- Re-reading meters the RF collector cannot hear
Not suited to
- Wired M-Bus meters — use the USB M-Bus converter
- Remote reading from the office; the terminal is carried on site
- Meters read over a LoRaWAN network
Questions
Which meters can it read?
Meters broadcasting EN 13757-4 / OMS telegrams are read. Devices using a closed, manufacturer-specific protocol fall outside that — the telegram structure is checked before commissioning.
What is the range?
Range depends on the building — concrete shear walls, lift shafts and metal cabinets all weaken the signal. A measurement taken from the landing shows the real coverage.
Where does the AES key come from?
The AES key comes from whoever sold or installed the meter. Without it the telegram is seen but its contents cannot be decoded.
Does a walk-by reading count the same as a remote one?
Yes. The telegram is matched to the meter in the project, written to the archive and enters the period's bill under the same rules — no different from a remote reading.
