Reference:Configuration/General/Update
On this page the device can be configured to poll an update server (a normal web server). The file configure with the URL is read from the update server and executed. This is an efficient mechanism to keep a large number of devices up to date. See Howto:Update Server for a detailed description of the available commands.
| URL | An URL, for example http://192.168.0.1/update/script-ip800.txt, pointing to a file whose commands are executed.
If the URL ends with a slash '/', for example http://192.168.0.1/update/, the device is adding the file name update-ipxxx.htm automatically, deduced from the device short name (for example update-ip800.htm). Furthermore the placeholder #h and #m can be used in the URL-String:
These placeholders may be used e.g. to address a device-specific directory (http://192.168.1.2/update/#h/script.txt) or to generate HTTP-GET parameters (http://192.168.0.1/update/script.php?mac=#m). If access to the command file requires authentication it must be configured within the HTTP-Client of the device. See Configuration/General/HTTP-Client. |
| Interval | An interval (in minutes) at which the file is re-read and executed. To restrict the update to certain hours (e.g. only during the night), there are mechanisms within the available commands to restrict the execution of the commands. The polling of the command file cannot be restrcited. |
