   ``<taskname>#<valuename>``
   As described already, each task can produced one or more events, one for each measured value. You should not name your devices and value names so that the combination equals to any of the below listed system events!
   ","

   .. code-block:: none

        on DHT11Outside#Temperature>20 do
         GPIO,2,1
        endon

   "
   "
   ``TaskInit#<taskname>``
   Triggered when a tasks ``PLUGIN_INIT`` was called.
   This can happen at boot, when a task is enabled, or ``TaskEnable`` command is used.
   ","

   .. code-block:: none

        on TaskInit#bme do
          LogEntry,'TaskInit task: %eventvalue1% result: %eventvalue2%'
        endon

   The first event value is the task index, the second event value is the return value of the ``PLUGIN_INIT`` call.
   The task index can be useful to store in a variable so the task index of a specific plugin like the dummy plugin can be stored to keep rules exchangeble among nodes regardless the order of tasks.
   "
   "
   ``TaskExit#<taskname>``
   Triggered when a tasks ``PLUGIN_EXIT`` was called.
   This can happen when entering deep sleep, when a task is disabled, or ``TaskDisable`` command is used.
   ","

   .. code-block:: none

        on TaskExit#bme do
          LogEntry,'TaskExit task: %eventvalue1% result: %eventvalue2%'
        endon

   "
   "
   ``TaskError#<taskname>``
   Added: 2022-06-21
   Triggered when a tasks ``PLUGIN_READ`` caused an error.
   The reason to trigger this error is plugin specific and this is not implemented for all plugins.
   For example, the BMx280 plugin will trigger this event when it was unable to start a measurement, for example when the sensor does not reply or its reply is unexpected.
   ","

   .. code-block:: none

        on TaskError#bme do
          LogEntry,'TaskError task: %eventvalue1% result: %eventvalue2%'
        endon

   The first event value is the task index, the second event value is a plugin specific indicator of the error that occured.
   N.B. The second event value can be a string.

   ``System#Wake``
   Triggered after power on.
   ","

   .. code-block:: none

        on System#Wake do
          GPIO,15,1
        endon

   ``System#BootMode``
   Added: 2021-10-18
  
   On ESP32 only.

   Event is sent right before network connection is attempted.

   On normal boots (GPIO-0 is high), the ESP32 can record the state of a number of pins and make these available after boot in the ``GPIO_STRAP_REG``.

   ","

   .. code-block:: none

        on System#BootMode do
          LogEntry,'Boot pins: GPIO-5: %eventvalue1%, GPIO-15: %eventvalue2%, GPIO-4: %eventvalue3%, GPIO-2: %eventvalue4%'
        endon

   The event values represent the state of these pins in the following order:

   * GPIO-5: ``%eventvalue1%`` (internal pull-up, default: ``1``)
   * GPIO-15: ``%eventvalue2%`` (internal pull-up, default: ``1``)
   * GPIO-4: ``%eventvalue3%`` (internal pull-down, default: ``0``)
   * GPIO-2: ``%eventvalue4%`` (internal pull-down, default: ``0``)

   The standard BootMode event will be: ``System#BootMode=1,1,0,0``
   
   N.B. When pulling down GPIO-15 during boot, the ROM bootloader messages will be silenced.

   N.B.2 Do not pull GPIO-2 high when GPIO-0 is low for programming mode.

   "
   "
   ``System#Boot``
   Triggered at boot time.
   ","

   ``System#Sleep``
   Triggered just before the ESP goes to deep sleep.

   ``MQTT#Connected``
   Triggered when the ESP has connected to broker.

	   on MQTT#Connected do
	    Publish,%sysname%/status,First message!
	   endon

   "

   ``MQTT#Disconnected``
   Triggered when the ESP has disconnected from the broker.
   ","

   .. code-block:: none

	   on MQTT#Disconnected do
	    Reboot
	   endon

   "
   "
   ``MQTTimport#Connected``
   Triggered when the ESP has connected to broker (the MQTT Import plugin uses a separate connection than the generic one).
   ","

   .. code-block:: none

	   on MQTTimport#Connected do
	    Publish,%sysname%/status,MQTT Import is now operational
	   endon

   "

	    Reboot

   ``WiFi#Connected``
   Triggered when the ESP has connected to Wi-Fi.
   ","

   ``WiFi#ChangedAccesspoint``
   Triggered when the ESP has changed to access point, will also trigger first time the unit connects to the Wi-Fi.
   ","

	   on WiFi#ChangedAccesspoint do
	    Publish,%sysname%/status,AP changed

   "
   "
   ``WiFi#ChangedWiFichannel``
   Triggered when the ESP is connected to the AP on a different channel, will also trigger first time the unit connects to the Wi-Fi.
   This has been added in build mega-20190910
   ","

   .. code-block:: none

	   on WiFi#ChangedWiFichannel do
	    Publish,%sysname%/status,channel changed
	   endon

   "
   "
   ``WiFi#APmodeEnabled``
   Triggered when the ESP has set the AP mode (access point) active.
   This may happen when no valid WiFi settings are found or the ESP cannot connect to the set AP, but it can also be enabled via some command.
   N.B. Sending a publish command may not be very useful on this event, since this will mainly happen when there is no WiFi connection.
   ","

   .. code-block:: none

	   on WiFi#APmodeEnabled do
	    ... // Some command
	   endon

   "
   "
   ``WiFi#APmodeDisabled``
   Triggered when the ESP has disabled the AP mode (access point).
   This can happen some time (default 60 seconds) after a WiFi connection has been made. Or disabled using some command.
   ","

   .. code-block:: none

	   on WiFi#APmodeDisabled do
	    Publish,%sysname%/status,AP disabled
	   endon

   "
   "
   ``Login#Failed``
   Triggered when (someone) has tried to login to a ESP unit with admin password enabled, but have failed to enter correct password.
   ","

   .. code-block:: none

	   on Login#Failed do
	    Publish,%sysname%/warning,Intruder alert!
	   endon

   ``Time#Initialized``
   Triggered the first time (after boot) NTP is updating the unit.

	   on Time#Initialized do
	    Publish,%sysname%/Time,%systime%
	   endon

	    Publish,%sysname%/NTP,Updated time at: %systime%

   "
   ``Rules#Timer=``
   As described already, triggered when a rules timer ends (setting a timer to 0 will disable the timer).
   ","

   .. code-block:: none

	   on Rules#Timer=1 do
	    GPIO,2,1
	   endon

   "
   "
   ``Clock#Time=``
   Triggered every minute with day and time like: Mon,12:30 or Tue,14:45. You can define triggers on specific days or all days using 'All' for days indicator. You can also use wildcards in the time setting like All,**:00 to run every hour.
   ","

   .. code-block:: none

	   on Clock#Time=All,12:00 do //will run once a day at noon
	    GPIO,2,1
	   endon

	   on Clock#Time=All,**:30 do //will run half past every hour
	    GPIO,2,1
	   endon

	   on Clock#Time=All,%sunrise% do //will run at sunrise  (%sunset% is also available)
	    GPIO,2,1
	   endon

   "
   "
   ``GPIO#N``
   If the command 'Monitor' is used to monitor a given pin you will receive an event for that GPIO as soon as it's state changes. As seen in the example you can always use the square brackets together with the task/value name of ``Plugin#GPIO#Pinstate#N`` to get the state, but to trigger events you need to add the monitor command (preferably at boot).
   ","

   .. code-block:: none

       on System#Boot do
        Monitor GPIO,15
       endon

        on GPIO#15=0 do
