Problem after reboot

[martellucci]

Hi, I’m using miflora-mqtt-daemon on RPI 3B+ and I’m very happy with it ;)

Only I’ve got a problem after reboot of the RPI when the daemon doesn’t start. The error is:

pi@Pi:~ $ sudo systemctl status miflora.service

I restart the daemon manually and it works well.

Can you help me?

Ciao

Hey!
Probably an issue with the availability of resources. Is the MQTT broker installed on the same system? Check if you have the latest service file version, which has a dependency on the network target.

The MQTT broker is on different server with different IP, but same LAN. The file is the last version.

I see exactly the same after a (or any) reboot on my Rpi 3B:

When the service is started again, everything is normal again.

MQTT is running on another system.

I added a wait in the service definition:

[Unit]
Description=Xiaomi Mi Flora Plant Sensor MQTT Client/Daemon
Documentation=https://github.com/ThomDietrich/miflora-mqtt-daemon
After=network.target bluetooth.service mosquitto.service

[Service]
Type=notify
User=daemon
Group=daemon
WorkingDirectory=/opt/miflora-mqtt-daemon/
ExecStartPre=/bin/sleep 30.  **<-------------------**
ExecStart=/usr/bin/python3 /opt/miflora-mqtt-daemon/miflora-mqtt-daemon.py
StandardOutput=null
#StandardOutput=syslog
#SyslogIdentifier=miflora
StandardError=journal
Environment=PYTHONUNBUFFERED=true
Restart=always

[Install]
WantedBy=multi-user.target

It looks like this delay helps. I guess the MQTT problem is caused by a service that has not fully started when miflora tries to use it.

IMHO the daemon should wait for the MQTT server to become available and gracefully shutdown if it doesn't reach it within a certain timeframe.

Happy to help if I can squeeze it in my busy schedule ;-)

Hey, unfortunately I have the same problem. Suddenly it stopped working and I can't figure out why. The MQTT Broker (mosquito) is running on a different server inside my LAN and anther service is able to use ist. And even this great tool was able some days before.

The log says only to check the config.ini but this is purely minimalistic.

Is there any way to see what actually failed?
