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:

volumes:

- /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'

# Set the following to True to have weewx use the WU "Rapidfire"

rapidfire = true

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!
