-This script changes the SSID when there is no connection to the selected Gateway.
+This package adds a script, that changes the SSID when there is no connection to
+the selected Gateway.
 
-Once a minute it checks if there's still a gateway reachable with 
+You can enable/disable it in the config mode.
+
+Once every timeframe it checks if there's still a gateway reachable. There can be
+selected two algorithms to analyze if a gateway is reacheable:
+
+- `tq_limit` enabled: define an upper and lower limit to turn the offline_ssid 
+  on and off in-between these two values the SSID will never be changed to
+  prevent it from toggeling every minute.
+- `tq_limit` disabled: there will be only checked, if the gateway is reachable
+  with:
+
+        batctl gwl -H
+
+Depending on the connectivity, it will be decided if a change of the SSID is 
+necessary: There is a variable `switch_timeframe` (for ex.  1440 = 24h) that 
+defines a time interval after which a successful check that detects an offline
+state will result in a single change of the SSID to "FF_OFFLINE_$node_hostname".
+Only the first few minutes (also definable in a variable `first`) the 
+OFFLINE_SSID may also be set. All other minutes a checks will just be counted
+and reported in the log and whenever an online state is detected the SSID will
+be set back immediately back to normal. when the timeframe is reached, there
+will be checked if the node was offline at least half the timeframe, only then
+the SSID will be changed.
