Information on collecting and using statistics about your installation
With the Miniserver, you can record any measurements, switching statuses etc. and summarise the results using statistics.
The recorded values can be represented graphically, exported as .csv files or displayed on the internet.
If the SD card is full, no more statistics are recorded and the recorded data is not overwritten. By accessing the FTP files through a FTP client individual records can be deleted to free up space.
For each input/output there is an option called 'Statistics'. The values can be measured according to certain criteria such as 'average over 5 minutes'. For digital inputs and outputs, the only option is 'each change'.
If you have selected the option 'each change', inputs which change their value or switching state very often will result in a large amount of writing to the SD card. This can lead to a high CPU/SD card load.
To prevent this, record averages over a set period of time. Digital inputs are therefore of limited use with statistics.
Statistics can generate large amounts of data. Using the option 'Compress Statistics', you can average values over a specified time period.
Example: A temperature sensor gives out a reading every minute. If the statistic is compressed every 30 minutes, 30 readings would be averaged together to give one average value.
Accessing statistics: Config
In the Miniserver tab of Loxone Config, select 'Download Statistics'. It's from here that you can then export them as a .csv file if you wish.
In the box to the uppper left hand corner you can select the range of dates you want to show the statistics over. Automatically this is the first date of the month. Then click Load.
All the recorded statistics for inputs and outputs will be shown and by clicking on one of these a graph will be displayed.
The Export button will automatically export the data as a .csv file for each input and output. The Ignore analogue 0 values button allows the statistics to hide 0 values.
When the memory card is full, no statistics are recorded.
