Add basic support for IKEA Fyrtur blinds by ggravlingen · Pull Request #26659 · home-assistant/core

ggravlingen · 2019-09-15T09:59:06Z

Description:

This PR adds basic support for the IKEA Fyrtur window blinds.

Caveat: I don't have one myself, so I need to find someone to test the code. I suggest this to be done before reviewing the code.

We use the IKEA constant in many platforms. We can move it to const.py in the package.

Hmm, looking more closely at it, I'm not sure it's being used at all. I'll remove it from all files.

We don't need to check for this. It's validated by the service schema already.

Thanks, removed it.

Fixed and changed in all files.

I've posted in the HA forums where adding support has been requested for and asked for someone to do a test against a real blind.

Thanks, I have a sneaking feeling there was something I'd forgotten in the process! Mind if I add a link to that blog post to the development checklist?

robbinonline · 2019-09-16T13:52:24Z

How can I test this?

ggravlingen · 2019-09-16T18:44:57Z

@robbinonline: clone my branch, run the docker script and start HASS. Pair the gateway as usual and the blind should be there.

robbinonline · 2019-09-16T19:20:08Z

Hmm that sounds like a big project. Not possible to install it like a custom component or update the changed files?

ggravlingen · 2019-09-16T19:30:16Z

I’m afraid I don’t know how that works. You need to update pytradfri to 6.3.0 and add a file to the tradfri folder but if that is possible as a custom component is beyond me.

The dockerfile ia dockerfile.dev (in my repo, not the official one) if you feel adventurous.

robbinonline · 2019-09-16T20:11:54Z

I have updated pytradfri to 6.3.0 and change .coveragerc and add cover.py. Do I also need the other files for the blinds?

ggravlingen · 2019-09-16T20:28:01Z

No, only cover.py.

ggravlingen · 2019-09-17T03:11:49Z

@robbinonline woke up this morning realizing I’ve forgotten to change one file. 🤦‍♂️ Will fix and post here when done.

robbinonline · 2019-09-17T06:21:51Z

Ah thats hopefully the reason its not working here, try it for hours yesterday 😅

ggravlingen · 2019-09-17T06:29:46Z

Really sorry about that 🙈 Its been a while since I last built something för HA.

robbinonline · 2019-09-17T06:37:07Z

Really appreciate it, looking forward to the updated code!

ggravlingen · 2019-09-17T07:53:21Z

@robbinonline the forgotten change has been added to the code now. You also need to update the __init__.py file.

robbinonline · 2019-09-17T09:44:59Z

@ggravlingen Allright update the code, and now the blinds shows up in the Integrations, only with the state: entity not available

Checking the logs:

Error doing job: Task exception was never retrieved
11:35 components/cover/__init__.py (ERROR) - message first occured at 11:35 and shows up 2 times

    raise NotImplementedError()
NotImplementedError

Did I miss something?

ggravlingen · 2019-09-17T12:40:12Z

@robbinonline you did nothing wrong at all and this is the reason we're testing 😄 It appears I needed to add a is_closed method. I've done so now but it might still be the case that it's not working and I need to add more methods that are required for the blinds to show up.

robbinonline · 2019-09-17T13:51:27Z

Allright, update the cover.py, now the blinds appear :)

But the controls don't work it only reads the state, and only updated the state by example how far are the blinds open after a restart.

MartinHjelmare · 2019-09-17T14:18:47Z

+        """Return if the cover is closed or not."""
+        if self.current_cover_position == 0:
+            return True
+


Add a return False here.

ggravlingen · 2019-09-17T14:45:32Z

@robbinonline that's a bit of progress then that we can track current state :) No errors in the log?

I've also adressed the comment of @MartinHjelmare but don't know if that will do anything to make changing the state work.

@MartinHjelmare sorry about spamming this PR. I can ping you when it's working if you want to turn off notifications for this PR?

MartinHjelmare

Don't worry about notifying me. I'm happy to see the progress. It's also easier to review small chunks at a time. 👍

robbinonline · 2019-09-17T16:44:42Z

@ggravlingen Update the latest cover.py nothing changes still no errors.

ggravlingen · 2019-09-17T16:48:56Z

@robbinonline please try again, I pushed some important changes 30 secs ago

cbromley · 2019-09-18T19:19:12Z

@juppe1969 you mention that the state of the blind is not updated? Is that on the latest version of the code as well?

I can confirm using the latest code that the blinds are not updating their status, seems to just read the state on HA boot. To test I moved all my blinds to closed, then restarted HA. On boot I saw the below details for the covers:

I then moved all blinds to 50% using the slider, waited 10 minutes but the covers all still showed the same as above. I also then repeated the same process starting with the blinds open and the results were the same as in no state or attribute update.

Edit: Just to add,
Open and closed all working for me now (as in not in reverse like yesterday), that's the open/close cover service and the set_cover_position service, 0 closing them and 100 opening. The slider also works but just doesn't remember the position.

MartinHjelmare · 2019-09-18T19:35:22Z

So something about the feedback mechanism probably isn't working correctly.

ggravlingen · 2019-09-18T19:35:31Z

@MartinHjelmare am I missing something obvious in the _refresh-method? Trying to figure out why HA is not updating. Just read the dev docs on polling and it seems it should be set to False for subscriptions. Also made a comparison against the light file and couldn't spot any obvious differences.

MartinHjelmare · 2019-09-18T19:38:52Z

Has someone tested the observation method in pytradfri with the blinds?

ggravlingen · 2019-09-18T19:41:03Z

@MartinHjelmare good point, I'll go back to pytradfri to find someone to test. This would have been so much easier if I'd had a blind. :)

ggravlingen · 2019-09-19T06:31:17Z

@MartinHjelmare I made some changes to pytradfri to see if we can fix the error that's starting to pop up with the new gateway firmware (#26673). Hence the version bump to 6.3.1.

MartinHjelmare · 2019-09-19T06:42:45Z

It would be better to put the library bump in a separate PR since we then could include it in a patch release since it's potentially a fix for a problem.

ggravlingen · 2019-09-19T07:19:43Z

@MartinHjelmare I agree and I will do so as I reckon it will take a bit longer to sort out observation.

There are a few people who are up and running testing this branch, including a few who experience the bug, so I figured it'd be an easy way of testing to just bump the version here.

ggravlingen · 2019-09-20T05:57:04Z

Argh, I rebased and messed up 🤦‍♂

ggravlingen · 2019-09-20T06:05:28Z

I'll fix this later tonight

ggravlingen · 2019-09-22T11:59:51Z

@MartinHjelmare when you feel the code is in line with HA standards, this one is good to go. I got confirmation on the forums that it works as expected:

Source: https://community.home-assistant.io/t/please-add-support-for-blinds-activated-in-the-ikea-integration/137253/38

MartinHjelmare · 2019-09-22T16:43:54Z

+    def __init__(self, cover, api, gateway_id):
+        """Initialize a cover."""
+        self._api = api
+        self._unique_id = f"cover-{gateway_id}-{cover.id}"


The entity registry is aware of the integration domain and platform domain of the entity, so adding cover isn't necessary.

I'll remove it but just a double check as I saw this in light and also noticed who made the change, so I figured it wasn't put there randomly?

The light platform has two kinds of entities, light and group. If there are more than one type of entity in a platform and the rest of the id is the same between the two kinds, we need to add a differentiator.

I don't know if this is actually the case for the light platform, ie if group.id and light.id are the same.

That makes sense, thanks for the explanation

MartinHjelmare · 2019-09-22T20:09:00Z

Can be merged when build passes.

ggravlingen · 2019-09-22T20:26:18Z

Thank you for the advice during review and to all the testers 🎉🙏
