How do I parse out the correct MQTT sensor from a topic that has multiple sensors data publishing?

[123 (Taras)]

What you have encountered is not uncommon. Your topic’s payload can contain “multiplexed” data. In other words, a single payload is used for reporting data from multiple devices. One time it may be data from device A and the next time it may be data from device B.

I suggest you consider implementing Strategy #2 described in the following topic:

Sonoff RF Bridge. Strategies for receiving data

Here are two strategies for receiving payloads published by a Sonoff RF Bridge (flashed with Tasmota firmware). Strategy 1: value_template In this strategy, all sensors are subscribed to the same topic published by the RF Bridge. The topic's structure depends on how you defined it when you configured *your* RF Bridge. This example will use `tele/RF_Bridge/RESULT`. Change that to whatever you have set for your Bridge. Because all sensors are subscribed to the same topic, a sensor will receive pa…

It describes how to create a “demultiplexer automation”. It’s purpose is receive the published data and re-publish it to separate topics, one topic per device. Then each one of your MQTT Sensors is configured to use a device-specific topic that receives payloads only meant for that sensor.
