      position: 5

#

this is what i have now. but the Position line at the bottom that says 5. should be the position that cover.lamellen_woonkamer_domoticz is set to

#

i tried replacing the 5 by trigger.attribute or cover.lamellen_woonkamer_domoticz.current but then the automation goes into error after reloading

#

You can use a template there to retrieve the value from the entity that triggered it. You have the right idea, just the wrong syntax.

#

{{ trigger.to_state.attributes.current_position }}
Something like that should do it.

#

The trigger object has (amongst other things), an object for the new state and the previous state of the triggering entity.

#

so every time you want to use a variable you need to put it into {{ }} (this is jinja2 notiation right?)

https://www.home-assistant.io/docs/automation/templating/

#

Yes, that's Jinja. More on that over in #templates-archived. But the trigger object is unique to automations, and that page I linked gives you more help.

#

i tried a few things but it keeps saying configuration invalid

#

in "/config/automations.yaml", line 16, column 0```

#

Share your automation again with the new template.

#

i forgot the double quotes 😄

green onyx Aug 16, 2021, 7:47 PM

#

I thought so 😉

#

JSON is valid inside YAML, so it thought you were just giving it another object.

#

how can i debug what the automation is doing? is there a way to see the full content of the trigger object when it ran?

is what i currently have. but when i reload automations and go to automations the automation is disabled and i cant enable it

#

You've given it an ID, which means you can use the trace tool to see the trigger object and anything else your automation references. But first, you have to get it enabled and run it at least once 😂

#

What does the command line config check say? Don't trust the UI one.

spring hedge Aug 16, 2021, 7:56 PM

#

there is a command line config check ? 😄

green onyx Aug 16, 2021, 7:56 PM

#

I can't do the bot commands here, take a look in the main channel

spring hedge Aug 16, 2021, 8:00 PM

#

on the link given by the bot i can not find a command to run on the cli
https://www.home-assistant.io/docs/configuration/troubleshooting/#problems-with-the-configuration
on the webui though if i go to logs it says
value must be one of ['close', 'close_tilt', 'open', 'open_tilt', 'stop'] for dictionary value @ data['type']. Got None. (See /config/configuration.yaml, line 8).
but it seems to me like this is not the real issue. since if i replace my variable by the number 5 it works as expected. so the set_position type should be valid

green onyx Aug 16, 2021, 8:04 PM

#

If might be a false positive. If there's no real trigger, the template won't give a value.

#

How did you install HA?

spring hedge Aug 16, 2021, 8:05 PM

#

loaded the qcow2 file into a proxmox vm

#

oh no. i tried that but in the end i found a script on github that downloaded HA and created a new VM in proxmox

green onyx Aug 16, 2021, 8:07 PM

#

HA OS then. From the command line (I have no idea how you get there), run ha core check

spring hedge Aug 16, 2021, 8:07 PM

#

okay so i ran the automation once while i set the variable back to the static 5
then looked at the debug.
so the object would be trigger.to_state.attributes.current_position
but it seems like as soon as i add a template to the automation the automation wont load with the error i gave above

green onyx Aug 16, 2021, 8:08 PM

#

Ah... you're using device actions 😂

#

The best advice we can give you about that is: don't.

#

Get used to using the services exposed by the individual integrations. It'll be something like cover.set_position for covers.

spring hedge Aug 16, 2021, 8:09 PM

#

green onyx Ah... you're using device actions 😂

dont expect me to know what im doing. only installed HA today ! 😛

green onyx Aug 16, 2021, 8:09 PM

https://www.home-assistant.io/integrations/cover/#service-coverset_cover_position

#

You're doing fine already.

#

The UI prefers to generate device triggers and device actions. They're not intuitive and there's little to no documentation on them.

spring hedge Aug 16, 2021, 8:13 PM

#

it fucking works 🎆

#

finally 😄

green onyx Aug 16, 2021, 8:14 PM

You can get way more clever once you have more stuff added to your HA instance but you've nailed the basics. Templates and service calls are the core of almost anything you'll do.
