mqtt:
 # The MQTT broker to connect to
 server: mqtt://mosquitto:1883
 # Optional: Username and Password for authenticating with the MQTT Server
 # Optional: for TLS client certificates
 # Optional: Used to specify ClientID. The default is <hostname>-<pid>
 # The Topic path to subscribe to. Be aware that you have to specify the wildcard, if you want to follow topics for multiple sensors.

 device_id_regex: "shellies/(?P<deviceid>.*)/.*"
 metric_per_topic_config:
   metric_name_regex: "shellies/(?P<deviceid>.*)/(?P<metricname>.*)"
 # Optional: Regular expression to extract the device ID from the topic path. The default regular expression, assumes
 # that the last "element" of the topic_path is the device id.
 # The regular expression must contain a named capture group with the name deviceid
 # For example the expression for tasamota based sensors is "tele/(?P<deviceid>.*)/.*"
 # device_id_regex: "(.*/)?(shelly-(?P<deviceid>.*?)/)"
 # The MQTT QoS level
 qos: 0
 # NOTE: Only one of metric_per_topic_config or object_per_topic_config should be specified in the configuration
 # Optional: Configures mqtt2prometheus to expect a single metric to be published as the value on an mqtt topic.
 #metric_per_topic_config:
  # A regex used for extracting the metric name from the topic. Must contain a named group for `metricname`.
  #metric_name_regex: "(.*/)?(?P<metricname>.*)"
 # Optional: Configures mqtt2prometheus to expect an object containing multiple metrics to be published as the value on an mqtt topic.
 # This is the default. 
 #object_per_topic_config:
  # The encoding of the object, currently only json is supported
  # encoding: json
cache:
 # Timeout. Each received metric will be presented for this time if no update is send via MQTT.
 # Set the timeout to -1 to disable the deletion of metrics from the cache. The exporter presents the ingest timestamp
 # to prometheus.
 timeout: 24h
json_parsing:
 # Separator. Used to split path to elements when accessing json fields.
 # You can access json fields with dots in it. F.E. {"key.name": {"nested": "value"}}
 # Just set separator to -> and use key.name->nested as mqtt_name
