Reading Parameters
Reading is done with the getelement command, with the following parameters:
...
The period field may not be specified, then the data of all time periods is deleted.
Analog sensor power reset
It is executed by the switchpower command (administrator rights required):
- k - user session ID.
This resets the power to analog sensors for the desired time (default 15 seconds). Used to reset the state of smoke detectors after they have been triggered. For the duration of the action, the operation of analog sensors is suspended. In the user web interface, this function is performed by the "Analog sensor power reset" element.
Hysteresis parameters
Additional parameters for managing hysteresis are read by the getelement command, set by the at0*x+at75 command, along with the rest of the sensor parameters.
