Hello,
I just buy a sensor from NKE.
http://support.nke-watteco.com/tic/
but… no decoder in javascript is available! So need to write one.
Maybe someone have already done this work? and could share it here?

thanks in advance if someone share it !
Hi @kelu28, there appears to be a JavaScript decoder page on their website.
http://support.nke-watteco.com/wp-content/uploads/2017/05/decodeZCL_svn5031.js
I don’t know if this is correct for your sensor.
No, this decoder have not all the sensors. Only those befor 05/2017.
Answer to me! but not finished

Things would be very wrong if the port number as passed by TTN is not already an integer. So, the original code referring to port should really be okay, for TTN. Why do you think you need this change? Is that to support ChirpStack (formerly known as LoRa Server)?
yes! it’s because I use ChirpStack for a another application
Hello,
I also need the decoder for Watteco TIC sensor hat would work also for Chirpstack server. Can you share the decoder you created ?
thanks
Wrong Forum! This is The TTN Forum for use by TTN/TTI/TTS users and paid for/supported by TTI & the foundation and the TTN Community. Chirpstack is an alternate system, with its own Forum (GIYF).
