MQRT

Small MQTT router. Allows creating multiple inputs/outputs and run action when input triggers.

Features

• multi-(input/output)
• multiple actions tied to the same trigger
• JavaScript filtering (run JS to check if message contains what you are interested in)
• JavaScript payload builder (run JS to build output message based on input message)

Configuration (incomplete):

# Define some input (name - "_" can be anything)
[input._]
type = "mqtt"
host = "127.0.0.1"
port = 1883

# ... with a number of triggers
[input._.trigger.single_click__hall_entrance_switch]
topic = 'zigbee2mqtt/hall_entrance_switch'
filter = { type = "json", field = "action", exact = "single_left" }
# ----- Note, that filter can also pass everything (default)
# filter = { type = 'no_filter' }
# ----- drop everything
# filter = { type = 'drop_all' }
# ----- check with JavaScript
# filter = { type = 'js', code = '''
# return JSON.parse(payload)['temperature'] > 20
# '''}

# ''' }
# ----- or
# payload = { type = 'js', code = 'payload.split(",")[0]' }

# Now, specify which action should be executed on trigger
