mqtt:
# The MQTT broker to connect to
server: tcp://127.0.0.1:1883

# Optional: for TLS client certificates
# ca_cert: certs/AmazonRootCA1.pem
# client_cert: certs/xxxxx-certificate.pem.crt
# client_key: certs/xxxxx-private.pem.key
# Optional: Used to specify ClientID. The default is <hostname>-<pid>
# client_id: somedevice
# 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>.*)/.*"
