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
# '''}
