Automation template - how to detect slider last and new state and compare it in action template

Configuration

    for i in range(10):
        service_data = {'host':'192.168.2.1', 'packet':'{}'.format(rf['C'])}
        hass.services.call('broadlink', 'send', service_data, False)
        time.sleep(0.55)

try this

cmd = data.get('command')

def call_service(hass, host, rfkey, count):
    rf = {
        "C":"JgBQAAABJpIUEBQ1FBAUEBQ1FDUUERM1FDUUERQ1FDUUEBQQFDUUEBQ1FBAUEBQ1FDUUEBQQFDUUEBQ1FDUUEBQQFDUUNRQQFAAFJAABJ0UUAA0FAAAAAAAAAAA=",

Hi @petro I tested your solution but not working.

Error:

Error executing script: name 'rf' is not defined
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/homeassistant/components/python_script/__init__.py", line 159, in execute
    exec(compiled.code, restricted_globals, local)
  File "ct_control.py", line 19, in <module>
  File "ct_control.py", line 9, in call_service

interesting. It seems it’s limiting the scope of the definition. I edited the previous post, try it again.

Still errors:

Error executing script: name 'hass' is not defined
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/homeassistant/components/python_script/__init__.py", line 159, in execute

It would appear you have to pass the hass object as a parameter to the call_service function in order to be able to use it within the function.

There’s an example of it in this recent post by Marius:

So you will have to change the function’s signature to this:

def call_service(hass, host, rfkey, count):

and modify every call to the function. For example, this:

call_service('192.168.2.1', 'C', 10)

changes to this:

call_service(hass, '192.168.2.1', 'C', 10)

Kind of odd that the scope doesn’t work properly in that env.

@lpt2007 made changes again

Now is working. :slight_smile: Thanks @123 and @petro

Here is link if someone have similar ir light.

I try to make new automation + python I already have working version with one problem.

Here is link.

On remote I have only one button of on and off. When I decrease fan speed and when I add slider to 1 automation call FAN + DOWN in python script because I configured it like that:

part from automation:

{% elif slider == 1 %}
  6

part from python:

elif cmd == 6:
service_data = {‘host’:‘192.168.2.1’, ‘packet’:’{}’.format(rf[‘FAN’])}
hass.services.call(‘broadlink’, ‘send’, service_data, False)
time.sleep(0.55)
loop = 1
rfc = rf[‘DOWN’]

Question: What I must add to line {% elif slider == 1 %} to only trigger that line when I increse slider?

When diff is positive number. --> {% set diff = (from - to) | round(0) %}

63

I figured out. Simple :slight_smile:

{% elif slider == 1 and diff == '-' %}

64

:thinking:

If diff is the result of a subtraction then diff == '-' will always return false.

I don’t know theoretically but I did like I say and is working :sunglasses:

66

I’m glad to hear it is working for you. Although, honestly, I don’t know what you expect it to do because the following statement will always evaluate to false.

{% elif slider == 1 and diff == '-' %}

For the elif statement to evaluate to true, both slider==1 and diff='-' must be true. The problem is diff=='-' is always false. So this elif can never be true and whatever code is underneath it will never execute.

You should listen to @123. He’s right. This will never ever be anything other than false.

This should only trigger on positive differences.

{% elif slider == 1 and diff > 0 %}
68

I don’t know why but solution you suggested not working.

My solution works :slight_smile:

{% elif slider == 1 and diff == '-' %}

Well you haven’t posted your full template so we are assuming you’re doing the math correctly. If you post the full template, we can help steer you towards a correct template and a robust automation.

Link is dead, is that a private repo? Can you just copy/paste the template?
