Data transmission

iSENSE smart monitoring product family uses the LoRaWAN data transmission network for data transfer. For those areas where there is no existing LoRaWAN network coverage, the network can be built regionally by the base station. 

Benefits of LoRaWAN communication network for use in district energy networks:

  • wireless
  • energy efficient
  • good underground penetration
  • possibility of two-way communication
  • easy deployment in LoRaWAN coverage areas

Cloud service

Real-time monitoring of iSENSE monitoring solutions is done through the iSENSE Online cloud service. Cloud service is available from all devices, anytime, anywhere, with SSL-protected login.


Commissioning of the system and training is done by Vexve experts.
