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!!

# How to read sensor value 
The three main items you want to pay attention to are the **SFI** (Solar Flux Index), the **K-Index** and the **A-Index**.

## Solar Flux Index
Summarization of the Sun's Radiation Output
* 70 – Not Good
* 80 – Good
* 90 – Better
* 100+ – Best


## Solar A-Index 
Daily Average of Magnetic Activity
* 0 – 7 Quiet
* 8 – 15 Unsettled
* 16 – 29 Active
* 30 – 49 Minor storm
* 50 – 99 Major storm
* 100 – 400 Severe storm

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?
