MQTT service does not start after reboot in demo

[raymar9]

Hi,
I’m experiencing an issue with Meter. When I reboot the Raspberry Pi (RPI), the MQTT service doesn’t work. To fix this, I have to log in to the web interface and manually press "Restart Data Collector." After that, MQTT starts working again. However, the problem reoccurs every time I reboot the RPI. It is the demo image.

Best regards,
Miha

Do you mean with "MQTT service" the smartmeter-datacollector service or mosquitto, the MQTT broker?

Could you check whether the systemd services for python3-smartmeter-datacollector and mosquitto are enabled when you access the RPi via SSH?

systemctl status python3-smartmeter-datacollector
systemctl status mosquitto

You can enable a service with systemctl enable python3-smartmeter-datacollector or systemctl enable mosquitto.
Enabling means that it starts during boot up.

I solved it by creating a restart service that runs 10 seconds after the Raspberry Pi boots.

sudo nano /etc/systemd/system/reset-smartmeter.service

content:

---

[Unit]
Description=Reset Smartmeter Data Collector Service
After=network.target

[Service]
Type=oneshot
ExecStart=/bin/bash -c "sleep 10 && /usr/bin/systemctl restart python3-smartmeter-datacollector"

[Install]
WantedBy=default.target

---

sudo systemctl daemon-reload

sudo systemctl enable reset-smartmeter.service

sudo reboot

Probably not the ideal solution, but it works :)

Nice! But why didn't systemctl enable python3-smartmeter-datacollector suffice? Did the service start but didn't produce any output or did the service just not start after booting?

I will check the startup behavior again the next time I use the demo image. However, I'm pretty sure that after configuration the demo automatically started and worked after rebooting, the last time I used the demo.
