Ah so its a per day maximum, that’s why it wasn’t showing in the hourly forecast. Pity its not hour based. I try to go out with my toddler avoiding the UV peaks in summer, which on clear days ofcourse is between 12 and 15, but on days when clouds and rain alternate with sunshine and the tempetature is relatively low, its easy to forget that the UV index is still likely quite high nevertheless.
I’ve released v0.13.0..
IMPORTANT: This version now includes a combined weather entity that has both observations and forecast data. The entity is the default device entity and has the name weather.weer_{location}.
This should make it easier to use weather cards that only support a single entity, and still use both observation and forecast data. The entity will be default for new locations. It’s still possible to enable the separate forecast and observation entities if you like.
Existing users will see 3 weather entities per location. You can choose to also disable the forecast and observation entity and switch over to the new one. Or disable the new one.

The combined entity is working great. I had ‘solved’ the separation previously by configuring two ha weather forecast cards but I was now able to migrate to a single card. Thanks! 
I’m not sure if my alerts were tied to the default Drenthe since I believe I configured the location before the feature so I re-added the location, to select the right region. Which was ‘painless’ btw.
(PS: I’m using this card: GitHub - troinine/ha-weather-forecast-card: ☀️ Slightly improved weather forecast card for Home Assistant · GitHub )
Thanks. I’m also using ha-weather-forecast-card for my dashboard. Really like it.
The alert region has always been a configuration option, from the very first release. You have always had it. I’ve seen the confusion with the alert region now popping up a couple of times. I probably need to do a couple of things:
- Make it a diagnostic sensor so you can always check what you’ve selected (easy)
- Make the location reconfigurable in ConfigFlow, so you can change the region
- Calculate the best region based on your location and make that the selected value when configuring
I’ve opened a PR for the first one, as that’s easy.
Hi Paul, sounds good! If it has always been there I may have forgotten I had set it. I did try to find the value of the setting but couldn’t find it quickly so just decided to re-set the location. 
Hi Paul,
I’m new to HA, NL Weather and this community as well. Your intergration seems to be working fine but not for me. When I enter the three API keys (copy paste from mail) then I receive an “Unknown error occurred” message.
Any ideas on how to solve this?
Thanks in advance
Dear Arnold. Can you check your Home Assistant log? I suspect there should be an error message visible there. Can you otherwise enable debug logging for the NL Weather integration (three dots on the integration page) and share the logging with debug logging enabled.
Hi Paul,
thanks for your response. After removing and installing the intergration it all works just fine.
Thanks again.
