AKOCONTROL

configuration

The AKOCONTROL devices has a series of parameters to configure its operation according to requirements, these parameters can be modified through AKONET.cloud, by accessing the device details and by clicking on the "Parameters” tab.

There are two types of parameters:

Changes to the parameters associated with AKONET.cloud have immediate effect, while the parameters associated with the device generate a task that runs in the next transmission (variable depending on configuration). Refer to the device manual to force the transmission.

If, upon altering a parameter, there is a pending task, the change is added to that task, otherwise it generates a new task. The list of tasks and their status can be consulted in the backlog section

The parameters are organised into 6 groups:

Some parameters are available depending on the device.

REMARK: Severity of alarms

Assigning different severities to different types of alarms allows classifying them according to their importance in order to subsequently be able to quickly identify them in the timeline graph or in the list of alarms.

Assigning severity (low, medium, high) to an alarm is necessary to define user notification rules.
