YAML & Jinja Templating Course Episode 1: Expressions, Statements, Comments, Variables, and Filters

[@SmartHomeJunkie]

What do you think about YAML and Jinja? Do you rather want to do everything using the UI of Home Assistant, or do you like to program your own advanced templates? Let me know in the comments!

[@Tafmie]

Thank you very much Ed! This is a series I have been waiting for for a long time. I'm already looking forward to the next episode!

[@jp_baril]

I want to do everything using the UI, but being able to at least understand existing yaml/jinja code is always useful.

[@hi-ccowboy7983]

I prefer YAML and Jinja. The UI is good, but I find it easier to visualize what I’m doing by looking at the code.

[@singaporepastor]

Excellent! It’s amazing how rare it is to find simple explanations for this stuff

[@ianrobson9612]

This series is going to be a lot of help. Thanks Ed

[@vancitydadbod]

Looking forward to the rest of the series!

[@peterg91]

This video just hits my current 1-week-long campaign to dive into JINJA and YAML, thank you!

[@waltervos8537]

Eindelijk voor mij meer duidelijkheid over het gebruik van Yaml en Jinja. Hier zat ik op te wachten. Dank je voor de heldere uitleg.

[@SmartHomeJunkie]

Dank je wel voor je fijne reactie!

[@major_west]

I've been struggling with YAML and templates. This is greatly appreciated!

[@edwaaij4752]

Hier was ik al een tijdje naar opzoek. Eindelijk Geweldig!

[@richardharnwell3331]

This is great! Really looking forward to the rest of this course!

[@stefan-lupo-pelzl]

I am sure many HA users will love to follow your series - including me. Great work. These tutorials will certainly increase the reach of your channel!

[@SmartHomeJunkie]

Thank you so much for your support! I'm glad you're enjoying the tutorials.

[@holohane]

Hi Ed, great video. I’ve been looking for something like this for a while. Even just explaining the difference between jinja and YAML is a big help. Thanks Eddie

[@dotmhd]

Hello, just wanted to tell you that I love your channel, you do a great job explaining everything we need to make our own Home Assistant setup. I hope someday you'll reach the million subscribers you deserve !

[@SmartHomeJunkie]

Thank you so much for your kind words! ❤️

[@wwolfram33]

Thank you for this type of content, as I could not find tutorials with explanations like this. I will begin my study of these episodes this weekend!

[@SmartHomeJunkie]

I'm glad you found the content helpful! Enjoy your weekend study session!

[@krzysztofkomornicki7007]

This is exactly what was looking for. Excellent job, Ed! Thank you so much for that!

[@SmartHomeJunkie]

Thanks! I'll make sure to keep up the good work to meet your high expectations!

[@DeliberateGeek]

Great content, as always! The Jinja documentation is very comprehensive, however, it's a much better reference than it is a tutorial. I'm a developer by trade and still struggled with it. Your explanations of the basics opened up a whole new understanding for me, which will allow me to take advantage of the excellent reference material on the Jinja site!

[@Kriss5054]

Great idea ! Even if I’m not a beginner, I learned a few interesting things. Thanks.

[@hi-ccowboy7983]

Just what I needed! Super thanks!

[@SmartHomeJunkie]

Thanks for your support!

[@pjuhl2313]

I'm not super comfortable with YAML or Jinja so I'm looking forward to these. Thanks Ed!

[@scottwhitaker1067]

Another top notch video. Looking forward to this series!

[@SmartHomeJunkie]

Thanks!

[@jeanlouisBarre]

Very useful, I wish I would have seen this before ! . There is a not documented JINJA filter : | bool that convert on or off that are strings to boolean true / false. This allows to use logical operation such as AND OR NOT easily. Of course one could use {{ is_state('light.kitchen', "on") }} but for logical expression such as {{ states('light.kitchen') | bool and states('light.garage') | bool }} bool filter can be useful. binary_sensor or input_boolean states are string and are not boolean. Therefore one has to use {{ states('input_boolean.xy') | bool }} to give a true / false result

[@kevinhenryviii]

I’m looking forward to this although I will go through each one slowly as I am a complete novice to this. Thanks Ed👍🏻

[@ElishaiPoran]

Thank you very much and very important and also allays concerns for new HA users.

[@SmartHomeJunkie]

Thank you for your kind words, they mean a lot to me!

[@LS-on6qf]

Excellent! short and useful introductory content

[@cedricdelecole3964]

Thanks a lot for this ! Using the code is indeed giving more flexibility than the UI, if we need more advanced features to be developped !

[@donnyf12]

Thanks so much for this. This is great content! Can't wait for more

[@homeautomatorza]

Thanks Ed This is great content which will help a great many, linking back now!

[@emms-place]

Great video Ed, Cant wait for the rest in the series

[@drumslapper]

Thanks Ed, looking forward to your clear explanations.

[@robRobblah]

Great job!! so clear. and super helpful. UI is great for most things, but some creative out of the box things require programming!

[@SmartHomeJunkie]

I appreciate your positive feedback! It means a lot to me.

[@pdz7197]

Grate job. Waiting for next one.

[@robertdon-duncan7954]

Thanks so much Ed for the simple explanations, I'm just getting into writing some custom code...without quite understanding what it is I'm writing. Trying to do some neat calculations around my energy consumption. This first video has already given me some confidence to keep going with it. Really looking forward to the rest of the series! Hoping you might go into calculations in some depth?

[@SmartHomeJunkie]

Yeah, that will be covered too.

[@MaWildcatHass]

Muchas gracias, muy útil el vídeo y la lista promete....

[@daveforrester61]

I love these tutorial type videos. I often use someone elses JINJA for what it does, without actually understanding how it does it. This for example: state: "{{ min([float(states('sensor.solaredge_m1_ac_power'), 0), 0]) | abs() }}" Hopefully you'll go down to the level I need to understand what this is doing to my sensor value, then I can replicate it and understand it. Thanks.

[@sygad1]

At last, i've been looking for a tutorial about this.

[@phgoossens]

Excellent video Ed! To answer your question, I started my HA many years ago when everything could only be done thru a yaml file. I believe there was no UI for dashboarding. Now I'm switching more and more to the UI. But up to now I mainly copy-pasted online pieces of code. Now I want to understand yaml and jinja and being able to build something from scratch. One of those things is the integration of my speed pedelec in combination with a Shelly plus plug to monitor the charging of the battery. When the battery hits the required loaded capacity, the Shelly plug droppes the charging process. But I''ve a little question about using variable. I followed your example but get an error message. I added a variable in my configuration.yaml as shown in your video. template: {% set accucapaciteit = "983" %} It gives me the message: Error loading /config/configuration.yaml: while scanning for the next token found character '%' that cannot start any token What am I doing wrong?

[@sevagjb]

Wow, that is awesome! Thanks Ed.

[@skm7812]

Well done! Thank you.

[@TonkaowGaming]

[@DeividasNarmontas]

Nice! It's very useful!

[@enriqueronda7239]

[@ictstelucjam3604]

Great video Ed! Love it, can't wait until next video. After the hole course maybe I can leave TheFes alone 🙂

[@TheFes]

Always happy to help

[@geoffreycoan]

Looks to be a really useful course Ed. I find Jinja and the differences between {{ and {% quite hard to understand and it usually takes several attempts before I can get my code to work!

[@mikaellume4657]

Great educatives videos as usual. Do you plan for an episode about how to deal with Date and Time in Jinja? Cheers

[@SmartHomeJunkie]

Yes sure!

[@Shaq2k]

Looking forward to it. Please go deep :)

[@gerwingal4430]

This will help a lot Ed, would be great if you could also touch upon calculating with values ( adding or subtracting, …) further a great video as always.

[@SmartHomeJunkie]

That will be absolutely covered!

[@francoisgrandcollot1027]

Great, thanks for discovering jinja. I have a question, how to get the daily consumption from this template " sensor.linky_papp is an instantaneous power in W " {% set kW_Grid = states('sensor.linky_papp') | float %} {{ (kW_Grid) / 1000| round(0, default=0) }}. Thank you for your help and happy new year

[@jedi939]

Thank you for doing this course. It is very helpful. If possible, I would prefer the examples to be larger on screen. They are hard to see if watching on a mobile phone.

[@SmartHomeJunkie]

I don't think developing templates on a mobile phone is an option...

[@vette5808]

Is there a way to get the embed code of a live streaming rtsp ip cam running in picture glass?

[@henriv3773]

Great course! It would help a lot if you would speek a bit slower so that we can make screenshots of the crucial images.

[@SmartHomeJunkie]

You can slowdown the speed in KZbin.

[@michaelthompson657]

Seems very hard 😂 I cant get the hang of templates!

[@Nick_1976]

Brilliant..

[@Siliconpixel]

Very useful thanks. I did find the pace a bit fast throughout. You need time to listen to what you are saying and also take in what’s being shown on screen. Nice production, great content as always though 😊

[@SmartHomeJunkie]

Thanks. Did you know that you can slow down the video in KZbin? There's an option in the settings of the video.

[@GuusdeRuyter]

great initiative. Please slow down a bit and please do not use dark mode, the code examples are hardly readable. Looking forward to the next episode.

[@SmartHomeJunkie]

Thanks. You can use the pause button or set playback to a slower speed. I will still use dark mode. Sorry. 🙃

[@scottwood646]

Thx for the video. I am also having a hard time seeing the code. Could you maybe zoom in more?

[@SmartHomeJunkie]

On what device are you watching this? It should be very clear on a desktop PC. These tutorials are not meant to watch on mobile devices because you will create templates on a desktop PC anyway.

[@scottwood646]

@@SmartHomeJunkie 70 inch screen in my living room mainly sitting 12 feet away. Looking at it in my office on my 32 inch monitor on my PC is not much better. For example, when you talked about adding comments, the text is not much different from the dark background. I have seen other videos where they zoom in a lot more on the text as they talk about it. That helps. to my eyes, the dark background is harder to see the text too. Thx again for the videos. I have watched you for a while now and enjoy your videos a lot.

[@dirkpennings9683]

Top Ed

Take it one step further and show the use in node red please.

Sorry, I don't do Node Red

[@Celeb2022MC]

Here is my suggestion, play time and focus on the commands instructions is less than your video also size of the window is small while explaining syntax
