Daemon connects and collects data but does not publish to openhab

[boilermanc]

Hi all, I posted this on the openhab forum but thought I would add this over here since its miflora specific.

I had this setup running just fine and then literally it just stopped updating. I’ll explain…

I have two pi’s running. One is the main pi and then one in a greenhouse (right next door) that is a pi zero. The pi zero just has the mqtt and miflora setup. It connects to the sensors and sends the data through mqtt just fine. it publishes to the same ip/broker as the main pi.

Nothing is showing in the log for the pi zero. Earlier I would get the confirmation that the message had come across like this:

2021-10-12 14:53:02.208 [INFO ] [openhab.event.ChannelTriggeredEvent ] - mqtt:broker:b57b164b67:sensor_4 triggered {"light": 902, "temperature": 17.9, "moisture": 0, "conductivity": 0, "battery": 100}
2021-10-12 14:53:02.231 [INFO ] [openhab.event.ChannelTriggeredEvent ] - mqtt:broker:b57b164b67:sensor_1 triggered {"light": 902, "temperature": 17.9, "moisture": 0, "conductivity": 0, "battery": 100}

Those numbers look the same because I had the same topic setup. Now fixed.

On the pi zero the mqtt broker is online and i have two channels, Sensor 1 and Sensor 2. They are both setup as “Triggers” and publish to a topic like this:

mqtt:broker:b57b164b67:sensor_4

topic: miflora/Sensor4

when that publishes of course it is on the same mqtt broker as the main pi and I have all my channels and things setup there to publish to a sitemap. again, all that worked fine. yesterday afternoon it just stopped publishing the updates to the pi zero log. I rebooted no joy. i test whether the miflora is running it is as you see in the log above but it does not publish in the openhab log and nothing is updating in the sitemap. Its like its running on the pi just publishing but not transitioning to openhab for lack of better description.

I have tried various reboot timings to see if something is not syncing. I think at a minimum I should be seeing the updates in pi zero log but nada.

thoughts?

thanks!

Hey @boilermanc thanks for the detailed description. It didn't become clear whether you actually checked your mqtt broker. I love mqtt as it creates a very transparent interface between two systems. Use MQTT Explorer or any other client to connect to you broker and have a look at messages. If the sensor_4 messages are published, something is wrong with your openHAB setup, if the messages do not appear this is a miflora-mqtt-daemon issue.

Good luck!

Hey @ThomDietrich thanks for getting back to me!

I ran MQTT Explorer and this is what is in the history.

{"Sensor4": {"name_pretty": "Sensor4", "mac": "C4:7C:8D:67:5B:1F", "refresh": 300, "location_clean": "", "location_pretty": "", "firmware": "0.0.0", "topic": "miflora/Sensor4"}, "Sensor1": {"name_pretty": "Sensor1", "mac": "C4:7C:8D:67:59:ED", "refresh": 300, "location_clean": "", "location_pretty": "", "firmware": "0.0.0", "topic": "miflora/Sensor1"}}

That looks all good. I am seeing Sensor 1 update now but Sensor 4 is not. I have gone through the configs and just not seeing where a difference would be. Sensor 4 look like it is connecting to the mqtt and publishing but oh is just no picking up.

Hey Thomas, I decided to shut down the pi zero and bring the sensors in to where the main pi is. They work fine there. Thinking there may be an issue with the zero so will rebuild and see what happens. Will keep you posted.
