LoRaWAN 863-870 ANALOG - Guide utilisateur / User guide version V2.0.1
Explanation of thresholds and hysteresis:
The monitoring period by the sensors is fixed at 10 minutes (to change this value, contact the Technical Support Department).
The settings associated with this mode of operation are:
• The transmission periodicity (zero in this usage situation) (register 301).
• The presence and type of external sensor (registers 320 and 322).
• The configuration of the events (registers 321 and 323).
• The high alarm threshold channel A (register 324).
• The high alarm hysteresis channel A (register 325).
• The low alarm threshold channel A (register 326).
• The low alarm hysteresis channel A (register 327).
• The high alarm threshold channel B (register 328).
• The high alarm hysteresis channel B (register 329).
• The low alarm threshold channel B (register 330).
• The low alarm hysteresis channel B (register 331).
A complete list of the registers can be found in paragraph 3.4.
