Cound not start miflora.service after reboot raspberry. about miflora-mqtt-daemon

[Nickolay40]

Hi, sorry. First comment on github.

[caveman2003]

Hi all, not sure if solved but if you run Raspbian Stretch you need:
[Unit]
...
After=network.target
...
[Install]
WantedBy=multi-user.target

There is an change from "After=networking.target" (Debian / Raspbian 8) to "After=network.target" (in (Debian / Raspbian 9)

How to make miflora service start with the system?(I new with *nix system, but wona now how it work) Because after command:
sudo systemctl start miflora.service
All start work fine!
Can you push me in right way?

[ThomDietrich]

Hey there 👋
the error is quite clear: "MQTT connection error." - My guess is, that your MQTT broker is not ready or not reachable at this point of the boot up. Which broker are you using where? Please be aware, that the service in it's default configuration will wait for the mosquitto.service to become available.

[General]

# The operation mode of the program. Determines wether retrieved sensor data is published via MQTT or stdout/file.
# Currently supported:
#    mqtt-json - Publish to an mqtt broker, json encoded (Default)
#   mqtt-homie - Publish to an mqtt broker following the Homie MQTT convention (https://github.com/marvinroger/homie)
#         json - Print to stdout as json encoded string

# The bluetooth adapter that should be used to connect to Mi Flora devices (Default: hci0)
adapter = hci0

[Daemon]

# Enable or Disable an endless execution loop (Default: true)
enabled = true

# The period between two measurements in seconds (Default: 300)
period = 300

[MQTT]

# The hostname or IP address of the MQTT broker to connect to (Default: localhost)
hostname = 192.168.1.69
# The TCP port the MQTT broker is listening on. SSL/TLS currently not implemented (Default: 1883)
port = 1883

# Maximum period in seconds between ping messages to the broker. (Default: 60)
#keepalive = 60

# The MQTT base topic to publish all Mi Flora sensor data topics under.
# Default depends on the configured reporting_mode (mqtt-json: miflora, mqtt-homie: homie)

# The MQTT broker authentification credentials (Default: no authentication)
#username = user
#password = pwd123

[Sensors]

# Add your Mi Flora sensors here. Each sensor consists of a name and a Ethernet MAC address.
# Additional location information can be added to the name, delimited by an '@'.
# Scan for sensors from the command line with:
#    $ sudo hcitool lescan

May be problem in screen

[Nickolay40]

In Mqtt dashboard i see message from miflora after reboot:

miflora/aspagarus/$announce
{}
miflora/$announce
{}

And I try to add line Restart=always in service, but still not want to start after reboot:

[Unit]

After=bluetooth.service mosquitto.service

Bellow pic.
systemctl list-dependencies miflora.service

[ThomDietrich]

Not sure what's going on. You'll need to test some more yourself. On my testing system it works just fine. Maybe play with the "After=" line a bit.

[Nickolay40]

so, I found the way - add delay in start. I think broker or bluetooth or something services did not time to start working.
sudo nano /etc/systemd/system/multi-user.target.wants/miflora.service

[Service]

StartLimitIntervalSec = 120
but after test this value can be increase about 180 sec

[ThomDietrich]

Interesting, but why did you close the issue?
Let's leave the issue open for others and if it's a recurring theme this should be added to the code here.

[ThomDietrich]

I see. No problem! ;)

Hi, I have the same (?) issue with my RPi 0W on Raspbian Stretch Lite.

What am I doing wrong?

https://stackoverflow.com/questions/38220995/systemd-unknown-lvalue-user-in-section-unit

Sounds like you've added the option to the wrong section

[zuberspace]

ah, right, my fault. It is now in the "Unit" section and doesnt throw an error but doesnt help either (with 180). Same issue on boot. Seems that the it doesnt wait for 3 minutes? its not so important for me because I dont restart the pi too often.

[ThomDietrich]

Nevertheless we should solve this issue for other users. I'm still unclear about the actual reason for it. The MQTT broker should be up in seconds....

[ThomDietrich]

Do you know some python?

Could you please open up the miflora-mqtt-daemon.py file and change these lines

miflora-mqtt-daemon/miflora-mqtt-daemon.py

Lines 154 to 160 in c275a27

	try:
	mqtt_client.connect(config['MQTT'].get('hostname', 'localhost'),
	port=config['MQTT'].getint('port', 1883),
	keepalive=config['MQTT'].getint('keepalive', 60))
	except:
	print_line('MQTT connection error. Please check your settings in the configuration file "config.ini"', error=True, sd_notify=True)
	sys.exit(1)

to

    try: 
        mqtt_client.connect(config['MQTT'].get('hostname', 'localhost'), 
                            port=config['MQTT'].getint('port', 1883), 
                            keepalive=config['MQTT'].getint('keepalive', 60)) 
    except Exception as e: 
        print_line('MQTT connection error. Please check your settings in the configuration file "config.ini"', error=True, sd_notify=True)
        print_line(e, error=True, sd_notify=True) 
        sys.exit(1) 

You should then see a more helpful error message in the log. Please post it here.

looks like the wifi is not up in time? my coverage is really bad on the balcony

[ThomDietrich]

Help me here: Why is the issue related to wifi? At least @Nickolay40 had his broker on the same Pi...

[zuberspace]

sorry, just wild guessing (read socket, connection and my wifi is bad there).

Im using mosquitto as a broker on another rpi with home assistant connected by ethernet to my fritzbox.

[ThomDietrich]

Could you look into https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget ?

edit:
Python is no problem but Im new to linux. My systemd-networkd doesnt work.

old

Doenst work. Im btw on Raspbian Stretch.
The first thing I did was to enable Wait for network on boot in raspi-config.
Then I enabled systemctl enable systemd-networkd-wait-online.service
and then even added After=network-online.target Wants=network-online.target.
