.. just updated a freshly installed Raspberry Pi with Buster to the latest version of Node-RED as described under [https://nodered.org/docs/getting-started/raspberrypi](https://nodered.org/docs/getting-started/raspberrypi) ..

Is there any reason why nodes installed via "manage palette" like Eztimer or Bigtimer are not available ?

Thanks ..

I just tried installing Eztimer on my Pi4 using 1.0.1 using the palette and it installed fine

(I already had Bigtimer installed)
