Device-level energy monitoring and remote power control
Smart Kablo adds device-level energy monitoring and remote power control to the PDU or wall outlet you already use. Track voltage, current, frequency, power and consumption; switch or power-cycle servers, PCs, NAS, switches and monitors from the mobile app. Wi-Fi/Bluetooth setup, SNMP and REST API integrations, UID identification, and C20, C14 or Schuko inputs make it a practical, scalable alternative to replacing an entire rack with a managed PDU.
