pve1 — Power-MQTT-Agent

CPU-Leistungsmessung (Intel RAPL) → MQTT → Home Assistant Auto-Discovery.

Installation (Stand)

Komponente	Pfad
Binary	`/usr/local/bin/pve-power-mqtt`
systemd	`/etc/systemd/system/pve-power-mqtt.service`
Konfiguration	`/etc/pve-power-mqtt.env`
Quellcode	`/root/code/pve-power-mqtt`
Repo	https://git.jeanavril.com/jean/server-power.git

Konfiguration `/etc/pve-power-mqtt.env`

POWER_MQTT_BROKER=tcp://homeassistant.iot:1883
POWER_MQTT_USER=server
POWER_MQTT_PASSWORD="F0x84rAOW#q@LX"
POWER_MQTT_HOSTNAME=
POWER_MQTT_CLIENT_ID=
POWER_MQTT_DISCOVERY=true

Leere Hostname/Client-ID → automatisch pve1 / pve-power-mqtt-pve1.

MQTT-Sensoren in HA

Entity (typisch)	Quelle
sensor.pve1_cpu_power	RAPL package-0
sensor.pve1_estimated_total	= CPU (kein GPU auf pve1)

Topics: homeassistant/sensor/pve1/cpu_power/state usw.

Details Broker: ../shared/mqtt-homeassistant.md

Build & Deploy (Update)

cd /root/code/pve-power-mqtt
git pull
export PATH="/usr/local/go/bin:$PATH"
go build -o pve-power-mqtt ./cmd/pve-power-mqtt
install -m 755 pve-power-mqtt /usr/local/bin/pve-power-mqtt
systemctl restart pve-power-mqtt

Oder aus Repo:

cd /root/code/pve-power-mqtt
git pull && ./deploy/install.sh
systemctl restart pve-power-mqtt

Betrieb

systemctl status pve-power-mqtt
journalctl -u pve-power-mqtt -f

Intervall: CPU alle 5 s.

Unterschied zu pve2

Kein nvidia-smi — nur RAPL
Kein nvidia-persistenced
Keine GPU-Topics

Troubleshooting

Problem	Lösung
HA „unavailable“	MQTT neu laden; `journalctl -u pve-power-mqtt` auf Connect-Fehler
session taken over	Client-ID prüfen — muss `pve-power-mqtt-pve1` sein
RAPL fehlt	`ls /sys/class/powercap/intel-rapl/` — Intel-CPU erforderlich
