<h3>alexa</h3>
<ul>
Module to control the integration of Amazon Alexa devices with FHEM.<br><br>
Notes:
<ul>
<li>JSON has to be installed on the FHEM host.</li>
<li>HOWTO for public FHEM Connector skill: <a href='https://wiki.fhem.de/wiki/FHEM_Connector'>FHEM_Connector</a></li>
<li>HOWTO for privte skills: <a href='https://wiki.fhem.de/wiki/Alexa-Fhem'>alexa-fhem</a></li>
</ul>
<a name="alexa_Set"></a>
<b>Set</b>
<ul>
<li>add <name><br>
Adds the device <code>name</code> to alexa-fhem.
Will try to send a proacive event to amazon. If this succedes no manual device discovery is needed.
If this fails you have to you have to manually start a device discovery
for the home automation skill in the amazon alexa app.</li>
<li>reload [name]<br>
Reloads the device <code>name</code> or all devices in alexa-fhem.
Will try to send a proacive event to amazon. If this succedes no manual device discovery is needed.
If this fails you have to you have to manually start a device discovery
for the home automation skill in the amazon alexa app.</li>
<li>createDefaultConfig<br>
adds the default config for the sshproxy to the existing config file or creates a new config file. sets the
alexaFHEM-config attribut if not already set.</li>
<li>clearProxyCredentials<br>
clears all stored sshproxy credentials</li>
<br>
</ul>
<a name="alexa_Get"></a>
<b>Get</b>
<ul>
<li>customSlotTypes<br>
Instructs alexa-fhem to write the device specific Custom Slot Types for the Interaction Model
configuration to the alexa-fhem console and if possible to the requesting fhem frontend.</li>
<li>interactionModel<br>
Get Intent Schema, non device specific Custom Slot Types and Sample Utterances for the Interaction Model
configuration.</li>
<li>skillId<br>
shows the configured skillId.</li>
</ul>
<a name="alexa_Attr"></a>
<b>Attr</b>
<ul>
<li>alexaFHEM-auth<br>
the user:password combination to use to connect to fhem.</li>
<li>alexaFHEM-cmd<br>
The command to use as alexa-fhem.</li>
<li>alexaFHEM-config<br>
The config file to use for alexa-fhem.</li>
<li>alexaFHEM-log<br>
The log file to use for alexa-fhem. For possible %-wildcards see <a href="#FileLog">FileLog</a>.</li>.
<li>nrarchive<br>
see <a href="#FileLog">FileLog</a></li>.
<li>alexaFHEM-params<br>
Additional alexa-fhem cmdline params.</li>
<li>alexaName<br>
The name to use for a device with alexa.</li>
<br>The following attributes are only relevant for custom skills:
<li>alexaRoom<br>
The room name to use for a device with alexa.</li>
<li>alexaProactiveEvents<br>
0 -> don't send proactiveEvents to amazon (default)<br>
1 -> send proactiveEvents to amazon<br>
devices that send proactiveEvents to amazon can be used to trigger alexa routines.<br>
setting alexaProactiveEvents to 0 in the alexa device itself will disable all event reporting for this fhem instance</li>
<li>articles<br>
defaults to: der,die,das,den</li>
<li>prepositions<br>
defaults to: in,im,in der</li>
<li>alexaMapping<br>
maps spoken commands to intents for certain characteristics.</li>
<li>alexaTypes<br>
maps spoken device types to ServiceClasses. eg: attr alexa alexaTypes light:licht,lampe,lampen blind:rolladen,jalousie,rollo Outlet:steckdose TemperatureSensor:thermometer LockMechanism:schloss OccupancySensor: anwesenheit</li>
<li>echoRooms<br>
maps echo devices to default rooms.</li>
<li>persons<br>
maps personIds to names.</li>
<li>fhemIntents<br>
maps spoken commands directed to fhem as a whole (i.e. not to specific devices) to events from the alexa device.</li>
<li>alexaConfirmationLevel<br>
</li>
<li>alexaStatusLevel<br>
</li>
<li>skillId<br>
skillId to use for automatic interaction model upload (not yet finished !!!)
</li>
Note: changes to attributes of the alexa device will automatically trigger a reconfiguration of
alxea-fhem and there is no need to restart the service.
