[feature request] - additional token for the last part of the topic name

[ps-nl]

Would it be possible to create an additional token, that contains only the trailing part of the triggering topic?

That would make it possible to run a single wildcard flow for a sensor that spits out multiple measurements into multiple topics. For instance:
/ESP_Easy/Sensor_name/Humidity
/ESP_Easy/Sensor_name/Temperature
/ESP_Easy/Sensor_name/Pressure

If these topics are watched as "/ESP_Easy/Sensor_name/+", the "trailing part" tag would contain the measurement name, while the "message" tag contains the measured value.

I tried hacking this myself, by creating an additional token in the app.json and processing the topic string in messagehandling.js with topic.split, followed by a pop() to get the last element. But my programming skills fall short, I am afraid.

I am not sure why you need this. The complete topic is returned (also when using + in the trigger card).
So if you register /ESP_Easy/Sensor_name/+ as topic, the current topic token will return /ESP_Easy/Sensor_name/Humidity,
/ESP_Easy/Sensor_name/Temperature or
/ESP_Easy/Sensor_name/Pressure

And what if you have multiple wildcards in a topic. A generic implementation is not that easy.

But if you want to hack yourself, you can check https://github.com/scanno/nl.scanno.mqtt/blob/beta/triggers.js#L88
there is the parsing of the topic.

You will need to add the parsing here
https://github.com/scanno/nl.scanno.mqtt/blob/beta/messagehandling.js#L24
and add the token there also

Hi Scanno, I know, but for my purposes what I need in the token is just the last part “Humidity”, “Pressure” etc. I’ll give it another go this evening to see if I can get it work. Best Peter

I managed to make it work. If you're interested, I can create a Pull Request

Here it is: #5

Sure, then I can take a look at it.

Is this still actual?
