Dynamic exposes

[daestx]

Hi everyone,

I have a CC2530 zigbee device that I have flashed with the PTVO firmware. I was able to integrate the device into my Homeassistant Zigbee2MQTT network without any problems.

In principle, I transmit measured value data in ASCII format. An external converter interprets the data and feeds it to my MQTT device.

That works so far. However, I would like to send the data dynamically and not generate unnecessary payload.

My device generates two types of data:

1. Cyclical data, with data that has different cycle times
2. Event-based data, when an event has occurred that generates new data.

I therefore only want to send data whenever new data is available. Only these should then be transmitted then.

I would then cluster the data and send it in defined telegrams. For example, my device could support two telegrams

1. "data1, data2, data3"
2. "data4, data5, data6, data7"

I found this issue about dynamic exposes

#9929

It describes how exposes can be assigned dynamically via fingerprints. However, it is not clear to me how I can send fingerprint information from my device depending on a selected telegram

But maybe there are other ways to send the data dynamically.

Anyone can help?
