Xiaomi Mi Flora Plant Sensor MQTT Client/Daemon gives the same data

I followed this instruction and ran the script. But it always gives me the same information and none of the values (battery, conductivity, etc.) changes. This is my config file:

# Configuration file for Xiaomi Mi Flora Plant Sensor MQTT Client/Daemon
# Source: https://github.com/ThomDietrich/miflora-mqtt-daemon
#
# Uncomment and adapt all settings as needed.

#reporting_method = mqtt-json

# The bluetooth adapter that should be used to connect to Mi Flora devices (Default: hci0)
#adapter = hci0

[Daemon]

# Enable or Disable an endless execution loop (Default: true)
#enabled = true

# The period between two measurements in seconds (Default: 300)
period = 5

[MQTT]

# The hostname or IP address of the MQTT broker to connect to (Default: localhost)
#hostname = localhost

# The TCP port the MQTT broker is listening on (Default: 1883)
#port = 1883

# Maximum period in seconds between ping messages to the broker. (Default: 60)
#keepalive = 60

# The MQTT base topic to publish all Mi Flora sensor data topics under.
# Default depends on the configured reporting_mode (mqtt-json, mqtt-smarthome: miflora, mqtt-homie: homie)
#base_topic = miflora
#base_topic = homie

# Homie specific: The device ID for this daemon instance (Default: miflora-mqtt-daemon)
#homie_device_id = miflora-mqtt-daemon

# The MQTT broker authentification credentials (Default: no authentication)
username = myUser
password = myPassword

# Enable TLS/SSL on the connection
#tls = false

# Path to CA Certificate file to verify host
#tls_ca_cert =

# Path to TLS client auth key file
#tls_keyfile =

# Path to TLS client auth certificate file
#tls_certfile =

[Sensors]

# Add your Mi Flora sensors here. Each sensor consists of a name and a Ethernet MAC address.
# Additional location information can be added to the name, delimited by an '@'.
# Scan for sensors from the command line with:
#    $ sudo hcitool lescan
#
# Examples:
#
Flower mate = C4:7C:8D:61:FC:F2
#JapaneseBonsai    = C4:7C:8D:44:55:66
#Petunia@Balcony   = C4:7C:8D:77:88:99
