[weewx-user] WeeWx and MQTT (clean session and QoS)

[Rui Pinto]

Hi!

I am using weewx to receive data from my weather station  and transmiting 
that data through MQTT.

I would like to know if it's possible to add QoS=1 and clean_session=false 
to the messages sent by WeeWx to the MQTT broker.

Best Regards.

[weewx-user] Publishing aggregate data, the topic is TOPIC/loop?

[Rui Pinto]

Hello!! 

These are my configurations for transmitting data through Weewx to the MQTT 
broker:

[StdRESTful]
...
[[MQTT]]
server_url = mqtt://username:password@localhost:1883/
topic = weather/default/default/VantagePro2/
unit_system = METRIC

aggregation = aggregate   

why the data is published to the TOPIC/loop? Is it because i'm publishing 
aggregate data so all the observations are pusblished in one go to the loop 
level?


Best Regards

The solution couldn't just be set the option retain to True?

[weewx-user] MQTT Weewx authentication

[Rui Pinto]

Hello!!

I'm trying to publish data to a topic in the Mosquitto broker through 
authentication. 
I succedd without authentication but i wanted to publish data with 
authentication.

I successfully changed the user and password in the mosquitto 
configurations, but i don't know where do i put the username and password 
in the Weewx configurations.

I don't know if i have to put the username and password in the weew.conf 
file...
Here's my configuration of MQTT in Weewx.conf: 

[StdRESTful]
[[MQTT]]
   server_url = mqtt://localhost:1883/
   topic = weewx/default/default/VantagePro2
   unit_system = METRIC

[weewx-user] Weewx SQLite storage

[Rui Pinto]

Hi!! I have a Davis Vantage Pro2 station and i'm using Weewx to save data 
aswell as displaying it using MQTT, Influxdb and Grafana.

I'm using a raspberry PI to connect to the station and I Weewx it's 
installed in the raspberry pi. The influx database is on another machine.
But Weewx stores automatically in a SQLite database locally, in other 
words, on the raspberry pi.

I want to store in a SQLite also, don't get me wrong but i don't want to 
store that data on the SD Card of the RaspberryPI, i instead want to store 
on a hard drive.

Is it possible to specify to the Weewx software where i want to save the 
SQLite Database?

Thank you.
Best Regards.

It's working fine. The only problem is that i don't understand what some

great.
