IoT application with optical readings of power meters

  • Analysis of consumption savings and dynamic advance invoicing
  • Monitoring the utilization of machines and equipment
  • Transfer of current consumption statuses and other parameters
  • Regular readings (15min-24h intervals)


Key features

  • Reading of meter registers (typically electricity meters) using the IEC62056-21 optical head
  • Absolutely easy installation (magnetic attachement)
  • More than 10 years without battery replacement with one reading per day
  • Version with 3 types of antenna terminals (center, left or right)
  • Possible connection to the SENSECOM-WSH repeater in SIGFOX for approx. 20 m for hard-to-reach places
  • Broadcasting to the SIGFOX nationwide network


  • OMD (-U)
    • universal mode with the possibility of setting up to 13 read registers
  • OMD – E
    • energy mode with fixed 4 registers (consumption in two tariffs, supply, electricity meter number)
  • OMD – x – C, L, R
    • antenna conector orientation
      • C…Central
      • L…Left
      • R…Right

Developed new models: OMDP – extension of OMD with the possibility of power supply via USB-C connector from a DIN power source in the meter cabinet or from a USB adapter or from a power bank. It will be suitable for applications with frequent, eg hourly readings.
