Wunderground Weather and Home Assistant

mcoulton · April 27, 2021, 2:24pm

Hello

I’m a Linux and HA newbie and I’m trying to add my personal weather station to HA. I’m using this document as my instructions.

The issue I’m having is I can’t locate the “custom_components” or .“homeassistant” directories refereed to below:

“To Install, copy the custom_components directory into your .homeassistant directory and the www directory into your .homeassistant directory.

or

copy the contents of the custom_components into an existing custom_components directory in your .homeassistant directory and the contents of the www directory into an existing www directory in your .homeassistant directory.”

1.) I have HA running on a Rasberry Pi 4 running Alpine Linux version 3.13. Even though I have an SD card installed, I don’t believe there’s anything on it (how can I check)?
2.) I do have a PSW and it’s registered with wunderground and I am able to get the API key.
3.) Are the instructions still valid for setting up a PSW within HA?
Thanks in advance for any help that can be provided.

Well, depends on the type of installation you are using - Docker or Supervised?
I can’t say for Docker, but I’m using Supervised and the mentioned directory is in “/usr/share/hassio/homeassistant”.

Thanks for the response.
It’s not in the “usr/share/…” directory as it doesn’t seem to exist. I don’t recall how I installed it on the Pi.

I would say most likely you are using Container or Core installation then. Afaik, in this case you can not use addons - see this table as reference.
You could still try the native integration though… however, I tried it but it didn’t work for me because of some changes in the API, so I ended up using the 3rd party (cytech) addon also.

I’ve found these directories and files. Is it possibly in one of these?

You need to check and see if WU is still giving out API keys. After IBM purchased WU, the program was cut back considerably.

What software do you use for your weather station. There may be different options to get the data you need. For instance, I use Weather Display and by using the built-in mqtt I am able to grab all the data I want. As I understand it, Ambience misspelled has a way through a bridge to do the same thing.

Lots of options out there.

AdmiralStipe · April 27, 2021, 4:58pm

Seems like it could be the correct one… costs you nothing to try adding the directories, files and configs :).

mcoulton · April 27, 2021, 5:26pm

Admiral Stripe - Thanks for your response. I’ll look into the directories further.

Edwin - Thanks for your response. I have an account with wunderground so I’m able to get an API key for for my weather station. This information is posted to wunderground and acurite.com. Apparently I should have the ability to pull info from wunderground and display it on HA (because I can obtain the API key). Other wise, as I understand it, I need to use a dongle and sniff out the data being transferred from the weather station to my weather station display unit.

I added the sensors of my PWS as explained here:

Hello
I looked at the link that Heinz provided and have added the following code. Please see below. It adds the sensors to HA but doesn’t populate them with any information. The url in “secrets” works in a browser so I know I’ve got the correct station ID and API key. Any ideas as to what maybe failing?

Quick update. I now seems to be working.

Hi all,

I’m struggling to get this to work with WUnderground. I know that my WU configuration is correct because I can find my station on WU. However, I get this error when checking the config.

I couldn’t put the the code into the config file described in the instructions because I have a separate sensors.yaml file. So I put the code in there.

- platform: wundergroundpws
  api_key: !secret wu_api_key
  pws_id: !secret wu_station_id
  numeric_precision: none
  monitored_conditions:
    - solarRadiation
    - neighborhood
    - obsTimeLocal
    - uv
    - winddir
    - humidity
    - dewpt
    - heatIndex
    - windChill
    - elev
    - precipTotal
    - precipRate
    - pressure
    - temp
    - windGust
    - windSpeed
    - precip_1d
    - precip_chance_1d
    - temp_high_1d
    - temp_low_1d
    - wind_1d
    - weather_1d
    - weather_1n

This is my folder structure for the WU code and icons:

Thoughts?

MilesAheadToo · September 14, 2021, 3:32pm

I resorted to using the RESTful sensor and it is working very well.

AdmiralStipe · September 14, 2021, 3:47pm

Not sure, but if you just copied the files to custom_components (or installed wundergroundpws via HACS), it would be good to restart HA and then try to add the code to sensors.yaml, otherwise HA may not recognize the addon as installed and therefore giving you error “integration not found”.
The code itself seems correct to me, at least I have the same one in my sensors.yaml.

gulo101 · September 20, 2021, 1:43am

Hello

I am having exactly the same problem:

I already deleted/re-added the files few times, any other ideas?

Thanks

mobile.andrew.jones · September 20, 2021, 2:23am

Did you restart Home Assistant? It wont know about the custom_components directory or any of the components in it until it’s been restarted.

gulo101 · September 20, 2021, 4:52pm

hm I did few times before posting. However today it started working so we’re good

assaff · October 4, 2021, 10:13pm

I’ve never used the restful sensor. I have a PWS connected to WU. Do you mind sharing how you did it?

I use the wundergroundpws integration, it has been working well for ages. I use a Davis VP2 PWS, which has a few sensors, including temperature and humidity, in its console. Is it possible to push the console temperature to HA and if so, what is the sensor name that I would need to add to my config file?
