What it does
NVS RF Terminal
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.

Questions
NVS RF Terminal — frequently asked
Are all brands of wireless meter readable?
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 do we get the key for encrypted meters?
The AES key comes from whoever sold or installed the meter. Without it the telegram is seen but its contents cannot be decoded.
Do collected readings feed the bill?
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.
