The aspect of templates that you are missing is types, you seem to be changing things to strings and not understanding why it’s wrong. There are 7 main object types, here’s a watered down description of them all.
int
a number without a decimal place.
1
float
a number with a decimal place.
1.234234
string
a series of characters. Denoted by characters wrapped in single quotes or double quotes.
'324dalkfsdjlk234'
"32342fsdkj32l4k2j3;523423442kja"
bool
true, false, 1, or 0
True
False
1
0
tuple
a collection of items. It cannot change shape, once it’s defined it will always stay that size. I.e. if I have 4 items, I cannot remove or add an item. Each item is identified by the order it was placed in the collection.
(1,2,3,'a','b','c')
Accessing items:
my_tuple[0] # Returns 1 (first item in tuple)
my_tuple[1] # Returns 2 (second item in tuple)
my_tuple[n] # Returns ? (n+1 item in the tuple)
my_tuple[-1] # Returns 'c' (lastitem in tuple)
list
a collection of items. You can add or remove items from it. You can filter it down. There are also some other operations that happen. Each one is identified by the order it was placed in the collection.
[1,2,3,'a','b','c']
Accessing items:
my_list[0] # Returns 1 (first item in list)
my_list[1] # Returns 2 (second item in list)
my_list[n] # Returns ? (n+1 item in the list)
my_list[-1] # Returns 'c' (last item in list)
dictionary
A collection of items. Each one is identified by a unique identifier, typically a string.
{'foo':1, 'bar':2, 'blah': 3, 'state':'my_state'}
Accessing items:
my_dict['foo'] # returns 1
my_dict.foo # returns 1
my_dict.get('foo') # returns 1
my_dict.get('junk', 74) # returns 'junk's value if it exists, if it does not returns 74
trigger
The trigger object is a bunch of nested dictionaries. It’s not a string. Learn this object through the docs.
Your Code
So with that all being said, the only valid code you have is
{{trigger.to_state.attributes["battery"] == 100}}
The rest seem valid but you’re making small mistakes. So lets look at them.
{{is_state("trigger.to_state.attributes['battery']",100)}}
is_state() accepts an entity_id as it’s first argument, and the state as the second argument. States are always strings unless it comes from an attribute. In the case of an attribute, it can be ANY object type.
Mistakes:
- You’re feeding the string
"trigger.to_state.attributes['battery']" as the first argument. Is this an entity_id? No. Should trigger even be a string? No.
- All states are strings. Is
100 a string? No, there are no quotes around it.
But even if you were to correct those mistakes, it still wouldn’t get the correct answer because you’re trying to get the result of an attribute. is_state only compares the state, not an attribute.
{{is_state_attr('trigger.to_state','battery',100)}}
is_state_attr gets compares an attribute to a result. It’s first argument is an entity_id, the second is the attribute name, and the third is the value you are comparing to.
Mistakes:
- You’re feeding the string
'trigger.to_state' as the first argument. Is this an entity_id? No.
- Even if you were to correct mistake 1 and remove the quotes, you’re accessing the wrong piece of information. You’re grabbing the trigger.to_state object, which is a dictionary, not a string. And it’s not the entity_id.
Putting it all together
{{ is_state_attr(trigger.to_state.entity_id, 'battery', 100) }}
{{ state_attr(trigger.to_state.entity_id, 'battery') == 100 }}
{{ trigger.to_state.attributes.battery == 100 }}
{{ trigger['to_state']['attributes']['battery'] == 100 }}
... etc ...
