Energy and utilities

Existing meters and valves, connected without replacing them and without new cabling.

Reading meters that have no data connection

A module fitted to an existing meter reads its pulses and sends the reading over wireless M-Bus, LoRa or Sigfox. The consumption data reaches the server and feeds automatic billing.

Our part

Technologies
  • Wireless M-Bus
  • LoRa
  • Sigfox
  • Pulse input
