Was always my go to if I needed something quick and dirty - just worked and even handled many devices where there was no immediately available decoder for insertion on TTN - e.g. the original Semtech/iMST LoRa MOTE/LoRaMOTE II, decoded directly on cayenne vs using decoder in TTN Application - didnt need much by way of documentation as was often a ‘follow your nose’ solution that was quite intuitive. But sadly as you say they announced at start of the month that the community vs commercial version is going EOL in just a few weeks… otherwise I would have dropped onto this thread to recommend when you 1st asked. Note whilst many criticise CLPP as not being the most efficient it just worked and is quite intuitive/straight forward and the format is often supported by other platforms so you may not need to modify any devices if set for CLPP depending on where you settle…
…Personally I will consult the Oracle for finding new home ( paging Nick!!!) @descartes that is ‘easy’ for us non-softies
