Alternatively, I could add a new API endpoint that automatically selects the nearest ionosonde to a given latitude/longitude (and also filters based on maximum measurement age and minimum confidence score). Would that appeal? Is there some standard format you would prefer to pass the lat/lon in?
Thanks @arodland for your comments. I was concerned about this originally, but couldn’t quite get the right Jinja template to work.
Your suggestion with a minor tweak of not using attr worked great. I’ve updated my original post with this: {{ (value_json | selectattr("station.code", "==", "MHJ45") | list | first).mufd | float(default=float("NaN")) }}
Also a big thanks for hosting, and sharing the code for, your excellent propagation maps/data

Hi, great work.
I’m not a programmer skilled home assistant user, is the upper code updated with the latest code that choose the nearest ionosonde to my location?
Will try to get it working…

Try adding
type: vertical-stack
at the top before cards:. I had the same issue.

Which files do I edit with the above configurations? I have my configuration.yaml split out and don’t put anything in it other than files / directories.
Where do I put the 2 ‘configs’? I’m not worried about the custom card, I can handle that.
Thank you.
The multiscrape can go in main configuration.yaml or whichever split out file makes sense. The rest sensor for Solar HF MUF needs to go with any other sensors you may have defined.

Hello everyone, I tried to facilitate the use of sensors for radio propagation.
I created a custom component that allows you to quickly have all the information.
You can install it via HACS Let me know your opinions and any suggestions.
Thank you

Hi @arodland i’ve develop a module to get data from hamqsl.com and soon i want to connect to your json to retrieve MUF data, if you can add new API that automatically select nearest inonosonde to a given position (lat/lon) we can biuld a very good service.
thanks in advance.

Can you add a sensor that detects Solar Flares?
I’m trying to find a way to create a sensor that detects Solar Flares. As an Ham Radio operator I will take advantage on that.
I’m not getting much info for HA, but there is a project that is close (https://community.home-assistant.io/…/solar-flux…/434299) but not relating the NOAA data into a sensor that results in a sensor that says “A Flare just happened! It’s a C9 flare”.
Can you help?

Hi new release v1.1.5 in pre-release available for update.
New X-Ray sensors:
-
The Class sensor is the modern classification system for solar flares and use letters A, B, C, M, or X, according to the peak flux in watts per square metre (W/m2)
-
The Scale sensor is the numerical representation of the Class sensor and can be used to trigger automations and notifications.

Is there an option for LUF (Lowest Usable Frequency) at all? I’m assuming it would be a sensor that needs to be configured. That’s useful, especially when there are solar winds/radio blackouts happening. There are times where the LUF is actually higher than the MUF.
Have a great day. 
Patrick.
hi Patrick, i never find LUF sensor in Hamqsl - kc2g.com and NOAA site.
If you know were read this data give me the site and i’ll try to integrate.

Bruno take a look
you can receive an alert when the solar flare are over your selected limit!!

Great integration!
Now, I just need to get familiar with “what to expect when there is a X flare”.
Many tks for your help.

I asked this on another topic as well. Recently, I started getting errors on the sensor:hf_muf and none of the cards work anymore. Has this been addressed at all, or am I the only one seeing it?
