MQTT plugin issue with JSON
Hi,
I have a complex setup where I monitor several components (rtl433, Zigbee ...) via MQTT with VerneMQ.
That MQTT is translated into zabbix y syslog data, so it can be reported on. I was using py-zabbix script, but it broke on debian12 updates, so I decided to migrate to MQTT native zabbix plugin instead, an avoid the middle man.
While the plugin is great, I've encounter a few issues:

While the plugin is great, I've encounter a few issues:
- Can't seem to be able to subscribe to 2 different topics from the same broker. Last subscription seems to take over..
- JSONpath doesn't seem to work after the first level:
- {"zigbee2mqtt_WC/Salon - Temperatura 5":"{"battery":100,"humidity":64.45,"linkqual ity":68,"power_outage_count":23837,"temperatur e":23.65,"voltage":3005}"} this is the message
- $.["zigbee2mqtt_WC/Salon - Temperatura 5"] this works and returns {"battery":100,"humidity":64.45,"linkquality":6 8," power_outage_count":23837,"temperature":23.65,"vol tage":3005} , which is OK.
- $.["zigbee2mqtt_WC/Salon - Temperatura 5"]. ["temperature"] doesn´t work
- If I create a new dependent item with $.["temperature"] , this works OK.
- I've tried multiple combinations and can´t seem to find the issue with my configuration, but I'm no expert on JSON.
