MQTT sensor "blinking" when payload doesn't always contain value?

[123 (Taras)]

@mmiller7

it pushes a LOT of different sensors I have so I need to make sure changes don’t break the others.

Are there multiple temperature sensors or just one?

If you have multiple temperature sensors, whose data is published to the same topic, you will need to adopt a strategy for demultiplexing it (i.e. assigning received data to the correct MQTT Sensor).

I proposed two ways of handling the issue in this topic. It’s for a Sonoff RF Bridge but the strategies remain the same for any device that multiplexes data from several sensors into a single MQTT 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…
