Urgent! Debug won't work. Can't see no data in Zabbix Front-End :(

[Sass-ctrl]

I cannot see any data in my Zabbix front-end after setting the keys I just implemented in the keys.csv file. I wanted to read the logs but there is no log under /var/log/....!

Also I have some questions regarding some variables:

1. in the config file I don't know what to set under:
   ---> what should I set there? ---> MQTT_TOPIC = /#
   KEYFILE = /etc/mqtt-zabbix/keys.csv
   ---> what should I set there? ---> KEYHOST = house

---

2. in the keys file what should I set for "hostname"? my broker?
   /bishopbriggs/gordonhouse/electricity/watts,mqtt.house.watts -----> ::hostname

If possible quick help would be great, I need your tool for a project!
Thanks a lot and greetings, Luca

I see everything you need in file /var/log/mqtt-zabbix.log
It's collect mqtt broker and zbxsend messages.
But yes, it's sent data wrong. Cause i see follow error
Got response from Zabbix: {u'info': u'processed: 0; failed: 1; total: 1; seconds spent: 0.000028', u'response': u'success'} 2020-06-28 15:53:17,400 processed: 0; failed: 1; total: 1; seconds spent: 0.000028
This means, server receives data but something wrong with it.
Now just try to do something
