MQTT Notifications

Icon Support: No
Message Format: Text
Message Limit: 268435455 Characters per Message

MQTT Support requires paho-mqtt (a version less then v2) to work:

pip install "paho-mqtt<2.0"

Syntax

Valid syntax is as follows:

mqtt://{host}/{topic}
mqtt://{host}:{port}/{topic}
mqtt://{user}@{host}:{port}/{topic}
mqtt://{user}:{password}@{host}:{port}/{topic}

For a secure connection, just use mqtts instead.

mqtts://{host}/{topic}
mqtts://{host}:{port}/{topic}
mqtts://{user}@{host}:{port}/{topic}
mqtts://{user}:{password}@{host}:{port}/{topic}

Secure connections should be referenced using mqtts:// where as insecure connections should be referenced via mqtt://.

Parameter Breakdown

Variable	Required	Description
user	no	The user associated with your MQTT server.
password	no	The password associated with your MQTT server.
hostname	Yes	The MQTT server you're sending your notification to.
port	No	The port the MQTT server is listening on. By default the port is 1883 for mqtt:// and 8883 for all mqtts:// references.
qos	No	The MQTT Quality of Service (Qos) setting. By default this is set to 0 (zero).
version	No	The MQTT Protocol Version to use. By default this is set to v3.1.1. The other possible values are v3.1 and v5.
client_id	No	The MQTT client identifier to use when establishing a connection with the server. By default this is not set and a unique ID is generated per message.
session	No	The MQTT session to maintain (associated with the client_id). If no client_id is specified, then this value is not considered. By default there is no session established and each connection made by apprise is unique. If you wish to enforce a session (associated with a provided client_id) then set this value to True.
retain	No	The MQTT publisher retain flag. By default this is set to `no`, but you may optionally over-ride it and set it to `yes`

Example

# Assuming we're just running an MQTT Server locally on your box
# Assuming we want to post our message to the topic: `my/topic`
apprise -vvv -b "whatever-payload-want" "mqtt://localhost/my/topic"

Sample Service Setup

I did the following to test this service locally (using docker):

# Pull in Mosquitto (v2.x at the time) - 2021 Sept 16th
docker pull eclipse-mosquitto

# Set up a spot for our configuration
mkdir mosquitto
cd mosquitto
cat << _EOF > mosquitto.conf
persistence false
allow_anonymous true
connection_messages true
log_type all
listener 1883
_EOF

# Now spin up an instance (we can Ctrl-C out of when we're done):
docker run --name mosquitto -p 1883:1883 \
   --rm -v $(pwd)/mosquitto.conf:/mosquitto/config/mosquitto.conf \
   eclipse-mosquitto

# All apprise testing can be done against this systems IP such as:
apprise -vvv -b "my=payload" "mqtt://localhost/a/simple/topic"

# Here is an example where the 'retain' flag is set:
apprise -vvv -b "my=payload" "mqtt://localhost/a/simple/topic?retain=yes"
