 * to implement:
     * make us of fields `keypadPaired` `lastAction` `doorState` `homekitState` `timezoneId` `accountUserId` 
     * build up some check script to make proof of correct count of columns and column order of the csv files
-	* collect data with time history:
-		* history of firmware changes
+	* collect data with time history (maybe with triggers):
+	    * BridgeFirmwareHistory: BridgeId, date, BridgeFirmware, BridgeWifiFirmware,BridgeAppVersion
+	    * SmartlockFirmwareHistory: SmartlockId,date,SmartlockFirmware
 		* history of rssi values
 		* history of state changes: locking states, pairing state
 * to test: this project was never tested with more than one Smartlock and more than one Bridge. We only have one! I also did not test what data output FOB will produce
 * Maybe give a try to send the JSON output files directly to JQ/Filebeat → Elasticsearch → Grafana Datasource for Elasticsearch ↔ possible?
-* Write some data collector tables like "BridgeFirmwareHistory" and "SmartlockFirmwareHistory" for tracking firmware changes utilizing some trigger
-	* BridgeFirmwareHistory: BridgeId, date, BridgeFirmware, BridgeWifiFirmware,BridgeAppVersion
-	* SmartlockFirmwareHistory: SmartlockId,date,SmartlockFirmware
