Description:
Parameters "Temperature Sensor X" may show sometimes abnormally high values 200,0; 200,1, etc. Those are not real temperatures, but rather error messages from the sensors with various meanings (See below).
In order to avoid those error codes to disturb the temperature reports, there is a way to filter them out.
Common causes:
The most common cause is that those values in reality error codes from the sensor and should be ignored or filtered.

Steps:
1- Login to LCM superadmin
2- Go to Objects
3- Search object by IMEI and click on Edit.
4- Scroll down to Custom inputs table.
5- Select a Custom Input and set it as shown in the image below.
Parameter1: Temperature Sensor X
Function: Custom
Constants: p1
MIN: -55
MAX: 125
(Note that MIN and MAX values have been set so that any value under or above it, including error codes, will be discarded).
Optional: You can also rename the Custom input to a more meaningful name (like "Temperature filtered")
Optional: You can recalculate up to 3 months before the present date.
6- Click on Save.
Result:
From now on, error values (any value above 125), will be discarded.
In its place, the last valid value will appear instead.
Example:
Temperature Sensor 0 | 5,0 | 200,0 | 200,1 | 6,0 |
Custom Input | 5,0 | 5,0 | 5,0 | 6,0 |
