SYNOPSIS

A MQTT Interface and Item module for Misterhouse

DESCRIPTION

This is the base interface class for Message Queue Telemetry Transport (MQTT) interface for use with any MQTT service, see (http://mqtt.org/) and (http//test.mosquitto.org/) for a broker and test service.

The current version supports the following wildcards

• single level wildcards e.g. +/devicename/+
• trailing multilevel wildcards e.g. stat/#

If the Last Will and Testament (LWT) parameters are set in mh.ini, it will connect with these and you need to send an online message when MisterHouse starts up e.g.

Example:

print_log( "sending LWT online message topic="
    . $config_parms{mqtt_LWT_topic}
    . " payload="
    . "online" );
$mqtt_1->pub_msg(
    message_type => MQTT_PUBLISH,
    retain       => 1,
    topic        => $config_parms{mqtt_LWT_topic},
    message      => "online"
);

INHERITS

INI PARAMETERS

CODE, require mqtt; #noloop
# address of the mqtt broker and port
mqtt_host=192.168.1.6
mqtt_server_port=1883
# topic to subscribe to
mqtt_topic=#
# mqtt Last Will and testament 
mqtt_LWT_topic=tele/Misterhouse/LWT
mqtt_LWT_payload=offline
# debug
mqtt_debug=0
# mqtt_user=user # (optional)
# mqtt_password=password # (optional)
# mqtt_keepalive=120 # (optional)

Items.mht

# define the broker
MQTT_BROKER, mqtt_1
# mqtt devic (tasmota in this case)
# MQTT_DEVICE, devicename, groups , broker, topic
MQTT_DEVICE, Workshop_cutout, Stay_off_at_night , mqtt_1, cmnd/Workshop_cutout/POWER
CODE, $Workshop_cutout->{states_casesensitive} = 1;

NOTE: by default, the Generic_item->set method converts values to lower case. If you are expecting to receive the same case as the MQTT messages, you need to set states_casesensitive for this device e.g.

$Workshop_cutout->{states_casesensitive} = 1;

or in items.mht as above.
