=head1 B<AlexaBridge>
=head2 DESCRIPTION
Module emulates the HUE to allow for direct connectivity from the Amazon Echo, Google Home, and any other devices that support the HUE bridge.
=head2 CONFIGURATION
The AlexaBridge_Item object holds the configured Misterhouse objects that are presented to the Amazon Echo or Google Home.
See <AlexaBridge_Item>
=head2 mh.private.ini Configuration
Note:
You must use port 80 for Google Home, it is locked down to port 80.
The user running MH must be root to run on port 80 or you have to give the MH user rights to use the port.
For Google Home and a reverse proxy (Apache/IIS/etc):
alexa_enable = 1
alexaHttpPortCount = 0 # disables all proxy ports
alexaHttpPort = 80 # tells the module to send port 80 in the SSDP response and look for port 80 in the HTTP host header
alexaObjectsPerGet = 300 # Google Home can handle us returning all objects in a single response
For Google Home using the builtin proxy port:
alexa_enable = 1
alexaHttpPortCount = 1 # Open 1 proxy port on port 80 (We default to port 80 so no need to define it)
alexaNoDefaultHttp = 1 # Disable responding on the default MH web port because Google Home will not use it any way.
alexaObjectsPerGet = 300 # Google Home can handle us returning all objects in a single response
For Echo (Chunked method):
alexa_enable = 1
alexaEnableChunked = 1
For Echo (Multi-port method):
This method should not be needed unless for some reason your Echo does not work with the Chunked method.
alexa_enable = 1
alexaHttpPortCount = 1 # Open 1 proxy port for a total of 2 ports including the default MH web port. We only support 1 for now unless I see a need for more.
alexaHttpPort=8085 # The proxy port will be on port 8085, this port should be higher than the MH web port so it is used first.
# All options
alexa_enable # Enable the module
alexaEnableChunked # Enable chunked return method (For the Echo)
alexaHttpPortCount # Amount of proxy ports to open
alexaNoDefaultHttp # Disable responding on the default MH web port
alexaObjectsPerGet # Amount of MH objects we return per GET from the Echo/GH
alexaHttpPort # First proxy port number
alexaMac # This is used in the SSDP response, We discover it so it does not need to be defined unless something goes wrong
alexaHttpIp # This is the IP of the local MH server, We discover it so it does not need to be defined unless something goes wrong
=head2 Defining the Primary Object
The object can be defined in the user code or in a .mht file.
In mht:
ALEXA_BRIDGE, Alexa
Or in user code:
$Alexa = new AlexaBridge(); # parent object
=head2 NOTES
The most important part of the configuration is mapping the objects/code you want to present to the module (Echo/Google Home/Etc.).
This allows the user to map pretty much anything in MH to a Echo/GH command.
ALEXABRIDGE_ADD, <actual object name>, <name you want Echo/GH to see>, <sub used to change the object state>,
<State mapped to Echo/GH ON command>, <State mapped to Echo/GH OFF command>, <sub used to get the object state>
<actual object name> - This is the only required parameter. If you are
good with the defaults, you can add an object like:
# In MHT
ALEXABRIDGE_ADD, AlexaItems, light1
# or in user code
$AlexaItems->add('$light1');
<name you want Echo/GH to see> - This defaults to using the <actual
object name> without the $. If want to change the name you say to the
Echo/GH to control the object, you can define it here. You can also make
aliases for objects so it's easier to remember.
<sub used to change the object state> - This defaults to 'set' which
works for most objects. You can also put a code reference or
'run_voice_cmd'.
<State mapped to Echo/GH on command> - If you want to set an object to
something other than 'on' when you say 'on' to the Echo/GH, you can define
it here. Defaults to 'on'.
<State mapped to Echo/GH OFF command> - If you want to set an object to
something other than 'off' when you say 'off' to the Echo/GH, you can
define it here. Defaults to 'off'.
<sub used to get the object state> - If your object uses a custom sub to
get the state, define it here. Defaults to 'state' which works for most
objects.
The dim % is the actual number you say to Alexa, so if you say "Alexa,Set
Light 1 to 75 %" then the dim % value will be 75.
The module supports 300 devices which is the max supported by the Echo
=head2 Complete Examples
MHT examples:
ALEXA_BRIDGE, Alexa
ALEXABRIDGE_ITEM, AlexaItems, Alexa
ALEXABRIDGE_ADD, AlexaItems, light1 light1, set, on, off, state # these are the defaults
ALEXABRIDGE_ADD, AlexaItems, light1 # same as the line above
ALEXABRIDGE_ADD, AlexaItems, light3, Test_Light_3 # if you want to change the name you say
ALEXABRIDGE_ADD, AlexaItems, testsub, Test_Sub, \&testsub
# "!" will be replaced with the action ( on/off/<level number> ), so if you say "turn on test voice" then the module will run run_voice_cmd("test voice on")
ALEXABRIDGE_ADD, AlexaItems, test_voice_!, Test_Voice, run_voice_cmd
User code examples:
$Alexa = new AlexaBridge(); # parent object
$AlexaItems = new AlexaBridge_Item($Alexa); # child object
$AlexaItems->add('$light1','light1','set','on','off','state'); # This is the same as $AlexaItems->add('$light1')
To change the name of an object to a more natural name that you would say to the Echo/GH:
$AlexaItems->add('$GarageHall_light_front','Garage_Hall_light');
To map a voice command, # is replaced by the Echo/GH command (on/off/dim%).
My actual voice command in MH is "set night mode on", so I configure it like:
$AlexaItems->add('set night mode !','NightMode','run_voice_cmd');
If I say "Alexa, Turn on Night Mode", run_voice_cmd("set night mode on") is run in MH.
To configure a user code sub:
The actual name (argument 1) can be anything.
A code ref must be used.
When the sub is run 2 arguments are passed to it: Argument 1 is (state or set) Argument 2 is: (on/off/<dim % interger>).
# Mht file
ALEXABRIDGE_ADD, AlexaItems, testsub, Test_Sub, &testsub
# User Code
$AlexaItems->add('testsub','Test_Sub',\&testsub); # say "Alexa, Turn on Test Sub", &testsub('set','on') is run in MH.
# I have an Insteon thermostat, the Insteon object name is $thermostat and I configured it like:
ALEXABRIDGE_ADD, AlexaItems, thermostat, Heat, heat_setpoint, on, off, get_heat_sp
# say "Alexa, Set Heat to 73", $thermostat->heat_setpoint("73") is run in MH.
ALEXABRIDGE_ADD, AlexaItems, thermostat, Cool, cool_setpoint, on, off, get_cool_sp
In order to be able to say things like "Alexa, set thermostat up by 2", a sub must be created in user code
When the above is said to the Echo, it first gets the current state, then subtracts or adds the amount that was said.
sub temperature {
my ($type, $state) = @_;
# $type is state or set
# $state is the number, on, off, etc
# we are changing heat and cool so just return a static number, we just need the diff
# because the Echo will add or subtact the amount that was said to it.
# so if we say "set thermostat up by 2", 52 will be returned in $state
if ($type eq 'state') { return 50; }
return '' unless ($state =~ /\d+/); Make sure we have a number
return '' if ($state > 65); # Dont allow changes over 15
return '' if ($state < 35); # Dont allow changes over 15
my ( $heatsp, $coolsp );
$state = ($state - 50); # subtract the amount we return above to get the actual amount to change.
$coolsp = ((state $thermo_setpoint_c) + $state);

I have a script that I use to control my AV equipment and I can run it via
ssh, so I made a voice command in MH:
$v_set_tv_mode = new Voice_Cmd("set tv mode [on,off,hbo,netflix,roku,directtv,xbmc,wii]");
$p_set_tv_mode = new Process_Item;
if (my $state = said $v_set_tv_mode) {
set $p_set_tv_mode "/usr/bin/ssh wayne\@192.168.1.10 \"sudo /usr/local/HomeAVControl/bin/input_change $state\"";
start $p_set_tv_mode;
}
I added the following to my .mht file:
ALEXABRIDGE_ADD, AlexaItems, set_tv_mode_!, DirectTv, run_voice_cmd, directtv, directtv
ALEXABRIDGE_ADD, AlexaItems, set_tv_mode_!, Roku, run_voice_cmd, roku, roku
