Description

Overview
The LoRa® SPY T4 long-range temperature sensor designed to monitor temperature in domestic hot water (DHW) pipes. It measures and records pipe temperature using an external PT100 surface probe. The device fixes to pipes with cable ties without damage and includes a reflector to eliminate external temperature influence. Connection to LoRaWAN enables secure encrypted transmission to the JRI MySirius cloud or to a client server. Real-time alerts notify of deviations from configured temperature thresholds.

Compliance
  • Meets regulatory requirements for legionella monitoring.
  • Complies with the decree of 1 February 2010 (healthcare establishments and public access buildings).

Connectivity and operation
  • Long-range LoRaWAN connectivity (operator network or private gateway).
  • Secure encrypted data transmission to cloud or client server; data accessible in real time via the MySirius application.
  • Ready-to-use with status and alarm LEDs and LCD display.
  • Touch-sensitive On/Off button; clear operation and alarm indicators.

Installation and use
  • Attaches to pipes with cable ties without damaging the pipe coating.
  • Built-in reflector reduces external temperature influence to ensure quality of internal measurements.
  • Integrated mounting eyelets and magnets for quick fixing.
  • Interchangeable battery for field replacement.

Benefits
  • Long-range LoRaWAN for wide coverage and remote monitoring.
  • Plug-and-play product with visible status and alarm indicators.
  • On-device LCD for immediate measurement readout.
  • High measurement accuracy for DHW monitoring using external PT100 surface probe.
  • Local indicators and simple interface for alarm acknowledgement and basic configuration.
