Welcome to the forum!

1. from [https://nodered.org/docs/getting-started/raspberrypi](https://nodered.org/docs/getting-started/raspberrypi)

### Autostart on boot

If you want Node-RED to run when the Pi is turned on, or re-booted, you can enable the service to autostart by running the command:

```auto
sudo systemctl enable nodered.service

```

1. install your tasmota devices and the Enocean / bluetooth button seperately. However I had problems with the enocean node and the tasmota node at the same time. see [Tasmota node not working after Tasmota 8.30 firmware update?](https://discourse.nodered.org/t/tasmota-node-not-working-after-tasmota-8-30-firmware-update/26740)  
Finally I used the tasmota plugs via MQTT and could use a Enocean based Hoppe door handle with my Enocean USB 300 stick and the enocean node.

I do not understand if that PTM 215B uses Enocean or bluetooth or both and whether it can be integrated in Node-RED at all.

Your screenshots indicate, that you may be not in the right directory when installing the additional nodes. If you installed Node-RED with the script from [https://nodered.org/docs/getting-started/raspberrypi](https://nodered.org/docs/getting-started/raspberrypi), you should change the directory to ~/.node-red, before you start `npm install ...`
