The ChirpStack Node-RED flows do not appear on the palette of my Node-Red 4.1.9 install on a Raspberry Pi 3B 1GB with 64bit trixie OS lite. I installed the flows using the command:
npm install @chirpstack/node-red-contrib-chirpstack
and the files chirpstack-api node-red-contrib-chirpstack are in the directory home/pi/node_modules/@chirpstack.
Node.js v24.15.0 and npm 11.12.1 were included in the clean install of Node-RED 4.1.9.
I am preparing a separate install of Node-RED after it was removed from Gateway OS 4.11.0. I installed a 64bit Raspian OS as 32bit will no longer be supported by Node.js v24 per the Node-RED website:
