+    * Bug fix for read back the active power limit from inverter #243 (before version 0.5.16 the reported limit was just a copy of the user set point, now it is the actual value which the inverter uses)
+    * Update the [user manual](https://github.com/grindylow/ahoy/blob/main/tools/esp8266/User_Manual.md); added section aobut the published data on mqtt; section about zero export control; added section about code implementation command queue 
+    * Added tx-Id number to packet payload struct. (eg. can be 0x95 or 0xD1) --> less messages fails and faster handling of changing power limit

 ## Active Power Limit via Setup Page
 If you leave the field "Active Power Limit" empty during the setup and reboot the ahoy-dtu will set a value of 65535 in the setup.
 That is the value you have to fill in case you want to operate the inverter without a active power limit.

+## Zero Export Control
+* You can use the mqtt topic ``<CHOOSEN_TOPIC_FROM_SETUP>/devcontrol/<INVERTER_ID>/11`` with a number as payload (eg. 300 -> 300 Watt) to set the power limit to the published number in Watt. (In regular cases the inverter will use the new set point within one intervall period; to verify this see next bullet)

 ## Issues and Debuging for active power limit settings
 Turn on the serial debugging in the setup. Try to have find out if the behavior is deterministic. That means can you reproduce the behavior. Be patient and wait on inverter reactions at least some minutes and beware that the DC-Power is sufficient.

+## Developer Information about Command Queue
+After reboot or startup the ahoy firmware it will enque three commands in the following sequence:
+1. Get active power limit in percent ( ```SystemConfigPara = 5 // 0x05```)
+2. Get firmware version (```InverterDevInform_All = 1 // 0x01```)
+3. Get data (```RealTimeRunData_Debug = 11 // 0x0b```)
+
+With the command get data (```RealTimeRunData_Debug = 11 // 0x0b```) the alarm message counter will be updated. In the initial case then aonther command is queued to get the alarm code (``` AlarmData = 17 // 0x11```).
+
+This command (``` AlarmData = 17 // 0x11```) will enqued in any operation phase if alarm message counter is raised by one or greater compared to the last request with command get data (```RealTimeRunData_Debug = 11 // 0x0b```)
+
+In case all commands are processed (```_commandQueue.empty() == true```) then as a default command the get data (```RealTimeRunData_Debug = 11 // 0x0b```) will be enqueued.
+
+In case a Device Control command (Power Limit, Off, On) is requested via MQTT or REST API this request will be send before any other enqueued command.
+In case of a accepted change in power limit the command  get active power limit in percent ( ```SystemConfigPara = 5 // 0x05```) will be enqueued. The acceptance is checked by the reponse packets on the devive control commands (tx id 0x51 --> rx id 0xD1) if in byte 12 the requested sub-command (eg. power limit) is present.
