Heartbeats

Heartbeats



A Heartbeat is a period in time in which a message is sent to/from a device to indicate the device status and health as well as to send any variable updates. A device will report lost communication if several heartbeats are missed. Endpoints heartbeat into their primary hub which is determined based on RF signal quality at the time of the last registration.

Heartbeat intervals vary by device.
  1. SBS 1x every 30 second
  2. Hub 1x every 5 minutes
  3. Sensor 1x every 60 minutes
  4. Valve Controller 1x every 5 minutes
The device heartbeat mode is a variable that can be adjusted for endpoints (sensors/valve controllers)

A device will report Lost communication after X missed heartbeats.
  1. SBS- 10 missed heartbeats = 5 minutes
  2. Hub- 2 missed heartbeats = 10 minutes
  3. Sensor- 2 missed heartbeats = 2 hours
  4. Valve Controller- 2 missed hearbeats = 10 minutes
