Help needed on how to distinguish multiple sensors in a JSON in a single MQTT topic

Configuration
1

Hi, I am looking for help on how to process a JSON I receive via MQTT from the BLE iBeacon hub (Minew BLE G1, a BLE 5.0 Wifi Gateway). The JSON contains multiple beacons under one MQTT Topic, the MAC address shoudl identify the beacon. I need to record battery state, temperature and humidity in HomeAssistant for logging and for use in other automations (turn on/off ventilation/heating/airco/etc).

Below an example of a single message received via MQTT on the topic beacon from the hub.

I was looking at this project but my problem is that I have multiple sensors within one single topic. How do I use the MAC address to distinguish them?

Have you figured this out? I am trying to do something similar and I’m stuck…

What have you tried? There are thousands of examples on the forums for this exact thing.

Not exactly the same. Or at least I couldn’t find one. I have spent all day today on this, digging the forum…
I already opened a separate topic on this here.
In none the examples I found was shown how to filter value_json.

Yes, but that post does not show how you are accessing the information from MQTT.
