TTN data from cloud to local node red....not supporting Pi

 I have set up a node for temp/humid in TTNWan, and a local zigbee2mqtt runs locally.

The Zigbee2mqtt runs on a pi3B+ with docker(IOTstack) together with node-RED.

There is a node-red-contrib-ttn seems able to get data from ttn to local(? wondering how they manage theIP)      

found example here: https://flows.nodered.org/node/node-red-contrib-ttn

you can install it through palette management, but nodes won't show up until you stop and restart node-RED from portainer.

But after installation from palette, the node shows up, but the contain is not exactly correct, there is no option of config as explained here:

https://github.com/TheThingsNetwork/nodered-app-node/blob/master/docs/quickstart.md

so I login to portainer and re install with npm command, it shows that my node version is outofdate.

Reading on git, https://github.com/TheThingsNetwork/nodered-app-node#the-things-network-node-red-nodes

these nodes are not supported on Pi...Why???

but it seems we can use MQTT in node red to get message from TTN...
