The controllers AKOCORE 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.

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.

Regulation and control (rE)
