# Settings for the MQTT Client. Currently only these three are supported
mqtt:
# The MQTT broker to connect to
server: tcp://localhost:1883
# Optional: Username and Password for authenticating with the MQTT Server
# user: bob
# password: happylittleclouds
# The Topic path to subscribe to. Be aware that you have to specify the wildcard.
topic_path: v1/devices/me/+
# 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: "(.*/)?(?P<deviceid>.*)"
# The MQTT QoS level
