Hi, I bought in past a CC2531 dongle and probably I bought it already flashed, I would test a Zigbee Tuya button for start a NR automation, I can find a ton of infos about this chip but I'm afraid it's hard to find the right infos for my case.

I'm running NR on Win10, I can recognize the dongle as COM serial port @9600 boud, is it correct?  
I tried to install Zigbee contrib module but it returns error, probably is not compatible with my nodejs version? The project is abandoned, they recomend to switch to Zigbee2mqtt but then I need a bridge between COM port and IP protocol, I've found [Koenkk](https://github.com/Koenkk) [zigbee2mqtt](https://github.com/Koenkk/zigbee2mqtt) project but Igot an error when instlaling it (pnpm not found)

```auto
Error: Command failed: pnpm run prepack
"pnpm" non e riconosciuto come comando interno o esterno,
 un programma eseguibile o un file batch.

```

so which other chances I have to get button events on NR? Thank you!

If you follow the documentation here [Windows | Zigbee2MQTT](https://www.zigbee2mqtt.io/guide/installation/05_windows.html#install-a-usb-to-uart-bridge-virtual-com-port-driver) you should install Node.js 22 LTS from their website. This includes corepack which when run (corepack enable) installs pnpm.

I haven't done this but I would think that this must work.

You will also have to install an MQTT broker, this is also mentioned on the above page.

if node-red is already running on this system, you can use `npm install` instead.

Ditch the 2531, they are rubbish and were superceded long ago by the CC2652.

Then install zigbee2mqtt as others have suggested.

Thank you mates for help, really appreciated! I've menaged to install pnpm using this: npm install -g pnpm  
anyway I needed also to update nodejs to the latest version.  
Now it's running, I need to connect a MQTT broker, I'll do it shortly
