7 Day Weather Forecast

DetroitEE · January 20, 2018, 6:51pm

I wanted to create a nice looking weather forecast inside of Home Assistant that uses the mdi icons, so it looks like the rest of my home assistant sensors. Sure you can use a weather app, but this just seems nicer, and since I’m looking at my home assistant app so much anyways, it makes sense.

This uses the dark sky sensor component, but could be applied using other weather components. Dark sky assigns the suffix _2, _3, _4 for the forecast 2 days out, 3 days out, etc.

Below is an image of the end result and the code to create it.
EDIT 1/24/2018: I’ve revised the code to incorporate the improvements made by @mconway and @arsaboo .
EDIT 3/4/2018: See arsaboo’s post #173 for the updated code using the friendly name templating, which was introduced in version 0.64. If this works for you, you no longer need the python script that updates the friendly names for the forecast sensors. Some Hassio users are reporting that the friendly name templating is not working for them; if that’s the case for you, just use the python script method described in this post to update the friendly names.

Save the following as weather.yaml in a folder called packages, add packages: !include_dir_named packages under homeassistant: in the configuration.yaml file. See home assistant’s documentation on packages for more information.

Python script to update the friendly names (save as dark_sky_friendly_names.py , place in /python_scripts folder and add python_script: to your configuration.yaml file. See python scripts component for more information.) NOTE: I’ve modified lines 25, 33, 41, and 49 to use ‘icon’ instead of ‘entity_picture’ so that the mdi icons work. If you want to use custom icons, see links to @arsaboo 's code on github below.

I’ve stripped out a lot of the if statements, i’m just working on printing the day names in the forecast. Right now I have “tomorrow”,“second”,“third” etc. Either way, I was able to reduce the lines of code by about 30%. Also got rid of the dependency of having weekday_number and weekday sensors. Hopefully I can wrap up the changes soon and repost for you. I’ve also turned this into a package

DetroitEE · January 22, 2018, 1:03am

That’s great! Thanks. I knew somebody could improve on this.

mconway · January 22, 2018, 8:04am

Alright, here’s how far I got tonight. It’s all in a package, and the names have comments for the template that would produce the correct rolling name. I haven’t figured out how to template the names yet. This may not be perfect, but it’s a start.

mconway/homeassistant-config/blob/master/packages/weather.yaml

homeassistant:

    group.weather_tab:

Very cool, I’m going to try out some of your modifications. Yes, templating the friendly names is one of the big issues I ran into. I don’t think I was ever able to get it working.

One comment, under forecast_fourth, the icon template sensor names still say “thursday” where they should say “fourth” (lines 163-181).

mconway · January 23, 2018, 6:27am

Woops, youre right! should be fixed now. Haven’t had time to look at the names more, but i’m sure there is a way.

arsaboo · January 24, 2018, 4:29pm

Looks like some icons are not updated in HA. I cannot see partly-cloudy-night and clear-day.

DetroitEE · January 24, 2018, 5:05pm

That’s weird, they should be showing up. The code has those two icon states and their corresponding mdi icons.

arsaboo · January 24, 2018, 5:17pm

I simplified everything to use entity_picture_template. Instead of using mdi icons, which are not exactly similar to the dark_sky icons, I am not using the dark_sky icons directly.

The updated code is available here. I am still not entirely happy with the structure and will update it soon.

arsaboo · January 25, 2018, 12:10am

I updated the whole code to use python_scripts that update the friendly names automatically. Here’s how it looks:

The python_script is here.
The weather package is available here.

This is fantastic! I would really like to incorporate this into my setup but I have a couple of questions.

I am not that familiar with including python_scripts, is that just an additional folder in my configuration setup? I saw that you have a line “python_script:” in your config file. I guess this doesn’t need an "!include . . " statement?
I also see you are referencing weather icons under your local folders. What icons are you using? Any chance you have a url to where you got them from?

Nice work to everyone on this.

Thanks!

DavidFW1960 · January 25, 2018, 2:00am

so in configuration.yaml I need to include the weather.yaml file? Where do I put the python script? I’m running hassio…

thanks - looks great.

DetroitEE · January 25, 2018, 2:09am

@photo64 @DavidFW1960

Under homeassistant: in your configuration.yaml file, put packages: !include_dir_named packages then create a folder called packages in your main configuration folder, and place weather.yaml in there.

For python scripts, add python_script: to your configuration.yaml file, create a folder called python_scripts in your main configuration folder, and place dark_sky_friendly_names.py in there.

DetroitEE · January 25, 2018, 2:18am

@arsaboo The python script to update the friendly names is great, nice work. One question: how do I make it so that it only updates the friendly name and leaves the icon alone? I tried commenting out lines 29 and 37, but it’s still not working, the icon is just the default eyeball. I want it to use the icon template I specify in the template sensor.

EDIT: I got it to work by replacing 'entity_picture' with 'icon' in lines 29 and 37. Not sure if there’s a better way to do it.

DetroitEE · January 25, 2018, 2:57am

I’ve updated the original post to reflect the improvements to the code. Note I’ve made a few tweaks to make it work with the mdi icons as I originally wanted. Thanks @mconway @arsaboo for your improvements.

arsaboo · January 25, 2018, 3:04am

Guys…just realized that the code has some bugs that need to be fixed. I will try to fix them and, may be, create a new thread will all the necessary details.

DetroitEE · January 25, 2018, 3:08am

What are the bugs? Seems to be working fine for me. Keep the updated code in this post if possible so it’s not the same information in multiple places. I’ll update the OP with any improvements.

EDIT: Ah I found one, the friendly names change back to “second”, “third”, etc. when the state gets updated. Should just need to add a trigger to the automation to run the name update script after any state change.

arsaboo · January 25, 2018, 4:08am

The friendly_name is not retained during updates. I have updated the entire script to use triggers. I am not sure this is the final version, so instead of copying the code in the OP, please just link to this post so that readers can access the most recent version of the code.

Please the following script under python_scripts

You will also need the weather.yaml package.

mconway · January 25, 2018, 5:17am

Thanks @arsaboo! I’ll update my configuration with this as well. I still prefer the MDI over the dark sky icons, but I’ll play with both and see which works best.

atomicpapa · January 25, 2018, 5:22am

@arsaboo I like those icons. Where did you get them?
