Jahresrückblick 2025 – unser neuer Blogbeitrag ist online! ✨

@Autodidakt sagte in Raspi 5 - 8Gb Arbeitsspeicher läuft voll:

Mem: 8.2G 4.5G 1.5G 9.7M 2.3G 3.7G

sieht doch gut aus!
Entscheidend ist available, nicht free!!

allerdings ist deine Load etwas h8ch.
nicht kritisch, aber in meinen Augen erhöht

[Autodidakt]

Ich frag mich nur, warum nach einem Tag ein Teil des Swap genutzt wird?

@Autodidakt sagte in Raspi 5 - 8Gb Arbeitsspeicher läuft voll:

Weil das Speichermanagement des Kernels das als vorteilhaft erachtet.
Ist per se nicht schlimm oder bedenklich. Nur wenn das dauerhaft zu 100% gefüllt ist sollte man mal schauen.

Nun bleibt noch ein Fehler:

z2m: Could not init sd_notify: The module '/opt/zigbee2mqtt/node_modules/.pnpm/unix-dgram@2.0.6/node_modules/unix-dgram/build/Release/unix_dgram.node' was compiled against a different Node.js version using NODE_MODULE_VERSION 115. This version of Node.js requires NODE_MODULE_VERSION 127. Please try re-compiling or re-installing the module (for instance, using `npm rebuild` or `npm install`).

npm rebuild und npm install bringen keine Besserung.

*** NodeJS-Installation ***

Was genau wo genau ausgeführt?

[Autodidakt]

npm rebuild und npm install im Raspberry Home verzeichnis

[Autodidakt]

War das das falsche Verzeichnis?

[Homoran]

npm rebuild und npm install im Raspberry Home verzeichnis

was hast du da denn von npm drin?

[Autodidakt]

Vermutlich nichts, weil ein fehler kam.

dann versuch es mal in /opt/iobroker

Du musst dich in das Verzeichnis

/opt/zigbee2mqtt/

stellen.

@Autodidakt

Du musst dich in das Verzeichnis

/opt/zigbee2mqtt/

stellen.

Der Fehler ist verschwunden, trotzdem nochmal in /opt/zigbee2mqtt/ ausführen?

Zu früh gefreut, Fehler ist noch da.

@Autodidakt

Ich kenne z2m nicht genau. Musste mal schauen wie man das neubaut. Sollte sich auf deren Homepage finden.

Google wusste die Lösung:

Re-compiling Zigbee2MQTT (Z2M) usually means fixing issues after an update or dependency change, often involving clearing the node_modules folder and reinstalling packages (e.g., rm -rf node_modules && npm install or pnpm i) or running npm rebuild for specific modules if you encounter errors like unix_dgram. This process helps resolve issues with missing or broken native Node.js modules, ensuring Z2M runs smoothly, especially after core updates or system changes like a new Node.js version.
