Hi all

I am enjoying a lot my Bresser Wifi Pro 5in1 weather station and I am pushing the data into my home assistant via the WeeWX docker. I first explain a bit how I did it, as it may help users with similar hardware, but at the end, I do have a question.

These are the things I did to get it working:

My weather station unfortunately did not allow for a direct connection to a home server, but it does allow for an upload to Wunderground. I created an account, and filled out the details and from then onwards, my station is sending data to Wunderground. But, I still wanted to capture the traffic for using in my home assistant. That's why in my ASUS router with Merlin firmware, I created some IP-tables to redirect the traffic to Wunderground to my WeeWx server:
 iptables -t nat -A PREROUTING -s bresserIP -p tcp --dport 80 -j DNAT --to-destination weewx-serverIP:3010 
iptables -t nat -A POSTROUTING -j MASQUERADE  

Now all packets will be redirected to port 3010.

Then I installed a docker container on my synology via docker-compose. The docker is from felddy, weewx. This combines MQTT,  weewx and the interceptor, as I am redirecting traffic.
--------------------------
version: "3.8"
services:
  weewx:
    container_name: weewx_bresser
    image: felddy/weewx
    init: true
    restart: "always"
    privileged: true
    network_mode: host    
    ports:
       - 8102:80
    volumes:
       - /volume1/docker/weewx/:/data
      - /volume1/docker/weewx/html/:/home/weewx/public_html/
    environment:
      - timezone=Europe/Brussels
      - WEEWX_UID=weewx
      - WEEWX_GID=dialout
-------------------
This docker requires in my data folder of course the configuration file. At first install, this file is created, then, you can fill it out. I copy here the most important parts of my weewx.conf.

        enable = true
        station = 'station_name'
        password = 'myKEY'
        
        # Set the following to True to have weewx use the WU "Rapidfire"
        # protocol. Not all hardware can support it. See the User's Guide.
        rapidfire = true

    [[MQTT]]
        server_url = mqtt://my_mqtt_server_IP:1883/
        topic = weather

So far, so good. Then, I copy here an excerpt of the logs of the docker:

So, in fact it all works nicely. There is a few (minor) questions I have:
- the docker is ignoring rainin and calculating the rain from the dailyrainin. I guess this works, but I do not understand why he is not sending rain data to Wunderground. In fact, as we are capturing directly a stream to rtupdate, why can he not just forward this stream. The rain data, originated from my weather station is in. 
- why does the docker upload twice, first as Ambient, then as Wunderground-RF?
- what if we want to use a newer version of WeeWx, and the Felddy container is not updated? 
- Is it possible to combine the Felddy container with other containers, or options, such as skins?
- I think that there is a newer version perhaps of the WeeWx-Interceptor. That's something I would like to try as well. 

I hope first of all that this may help people getting started with this. I am very happy and grateful that these dockers exist and now, via MQTT, this data is sent to my home assistant! But, as I like to be up-to-date, I also hope there are options to get updated packages, or include the reports and an own website via the containers. 

Thanks a lot!

And there seems to be a second issue, look at the logs:

Rain_total = 0.01 (inch), which stems from dailyrainin, but this is not saved in dayRain or rain, as it is 0.0. 

Thank you for your help.

Hi all

everything is solved, I created my own docker, based on https://github.com/Daveiano/weewx-wdc-interceptor-docker.
Now I am running v5.1.0 and have no issues anymore. 

Many kudos to Daveiano for creating this simple github. This helped me to get the 5.1.0 working on my Synology.

Kris
