echo "Now you need to create database and check credentials in config files:
    * /etc/teslamate.conf
    * /var/lib/grafana/conf/provisioning/datasources/teslamate.yml

Create the teslamate database:
# psql -U postgres -c \"create database teslamate;\"
# psql -U postgres -c \"create user teslamate with encrypted password 'secret';\"
# psql -U postgres -c \"grant all privileges on database teslamate to teslamate;\"
# psql -U postgres -c \"ALTER USER teslamate WITH SUPERUSER;\"

# grafana-cli plugins install natel-discrete-panel
