Changing settings at scale.
WHAT IS TYPICALLY CONFIGURED
Reporting intervals Thresholds Server addresses Feature switches Calibration values
WHAT TO NEVER HARD-CODE
Server addresses.
WHY
Changing infrastructure otherwise requires a firmware update to every device.
WHAT TO GROUP DEVICES BY
Type, firmware version, customer, site, or role.
WHY GROUPING MATTERS
Changes apply to sets, and targeting individuals does not scale.
WHAT TO ROLL OUT PROGRESSIVELY
Any configuration change.
WHY
A bad setting applied everywhere at once can silence the entire fleet.
WHAT TO ALWAYS PROVIDE
Defaults the device uses when configuration is unavailable.
WHAT TO VALIDATE ON THE DEVICE
That received configuration is within permitted bounds.
WHY
An erroneous value could stop reporting entirely, after which it cannot be corrected remotely.
WHAT TO IMPLEMENT
Reversion to the last known good configuration, if the new one prevents connection.
WHY THAT IS ESSENTIAL
It is the only defence against remotely disabling your own fleet.
WHAT TO MONITOR
Which devices have applied which configuration.
WHAT TO ALERT ON
Devices not applying changes.
