Home Assistant Templating Masterclass (Full Course)

[@blakebowden955]

Love this video - I have routinely come back every 4 or 5 months since you've released it as a refresher. Would love to see another masterclass with the new templating options HA has. Thanks for everything you do!!!

[@SmartHomeMakers]

Appreciate your comment Ben, which part did you enjoy the most ?

[@BenGmuN]

@@SmartHomeMakers Well, thanks to your explanation of setting variables, I was finally able to figure out how to create a sensor that would show me the last command issued to any of my Alexa voice assistants. {% set last_alexa = expand('group.voice_assistants') | selectattr('attributes.last_called','eq',true) | map(attribute='entity_id') | first %} {{ last_alexa }} {{ state_attr(last_alexa,'last_called_summary') }}

[@SmartHomeMakers]

@@BenGmuN Very smart! and which automations are you building from this sensor?

[@BenGmuN]

@@SmartHomeMakers Thanks! So, I actually just wanted to display the last Alexa command in Lovelace, but I'm thinking about attempting to use it to build an automation for context-sensitive voice control of curtains, blinds and TVs, i.e. if I'm in the lounge and say "Alexa, open curtains", my automation will know I want the lounge curtains because the command originated from the lounge Echo - I don't have to say "Alexa, open the lounge curtains" Make sense? Not sure how I achieve this though. Currently, I'm using a separate automation for each different TV, blind, and curtain, which is a bit complicated.

Brilliant video. Very clear. I learned lots from this video. Thanks a lot. Just have a question: How do we use global variants in templates? For example: - binary_sensor: - name: "On fire" state: > {% set AlarmTemp = 50 %} ..... attributes: test: "{{ AlarmTemp }}" I define AlarmTemp in "state", and want to access AlarmTemp's value from "attributes".

[@SmartHomeMakers]

Hi Dong! You can create your own sensor in the configuration.yaml and refer to it!

[@anyDiy]

@@SmartHomeMakers Yeah, I found the way. Thanks a lot.

[@picotrain5959]

Question: In the example you used for ground temp you used {% %} for the variables and then used {{ }} for the statement which I understand completely. I also understand you could have also listed all the variables and the math completely in the statement itself. So my question is, what’s the difference if any and or the pros and cons to doing it the 2 different ways. I have a template sensor that reports a room temp based on multiple temp sensor sources in the same room, but have simply listed all the sensors and the math in one statement and never considered doing in any differently? Thanks for the great videos and if you don’t mind me saying they are getting better with each and every one 😉

[@SmartHomeMakers]

Just how easy it is to read, when doing these videos and sharing code sometimes I need to break things down a bit. Also good to verify your math as you go along

[@muellerworld]

Great tutorial, thank you. I am, however, running into a few syntax issues: What version of HA was this video made for? Has HA made some syntax changes since this video was released? For example, I get errors with: {% for state in states.sensor | selectattr('attributes.device_class','==','temperature') %} However, this works: {% for state in states.sensor | selectattr('attributes.device_class','defined') | selectattr('attributes.device_class','==','temperature') %} Also "unknown" errors with this: {{ states('sensor.date') }} Is there new syntax for HA Templates in 2023.6.3?

Goal is, to show this voltage value in a CBC that switches another sensor either by replacing ‚status‘ or ‚name‘ of that card. That was ( for me) missing in that tutorium, to make it perfect. But thanks again, I appreciate you’re video and I’ve learned a lot.
