Is adding Home Assistant the right way to go?

Hilt

I too use HA in a container on Synology. I make the dashboards within HA and use iFrame’s to display them on the MagicMirror. This way you can make the dashboards as pretty as you like. You really don’t have limits.

To get some idea :

https://forum.magicmirror.builders/topic/19738/home-dashboard?page=1

Initially I was running an older version of MagicMirror and I had to add the following in the configuration.yaml file of Home Assistant to have them to display :

http:
  use_x_frame_options: false

To be fair, I haven’t tried excluding this since I rebuilt the MagicMirror using the latest build at the time. But it’s still in there today and isn’t causing any harm. It was more a HA workaround in any case

@Hilt @sdetweil sorry for the delay in response. School holidays, plus investigating options for heat pumps and keep getting distracted. I did manage to install Docker and Portainer (hadn’t seen your response yet) to my Pi and so am going to have a play with HA today. However, also going to check all your suggestions to see what can be useful :)

@British_Kiwi have fun. Lot to learn…

Hey Sam

Hope you are having a good week! I’m back! I have had a fun week playing with MM and HA and with a few issues with permissions which I finally fixed I am certainly getting there. So have a couple of questions for you (or anyone else reading along)

So my set-up is RPi5 with Bookwork. MM is on there and I have used MMM-pages - first page is things like my calendars, weather etc. Second page is currently my testing page, and am going to put the HA on there.

I have used Docker and Portainer on the RPi for HA. I have created a Dashboard for our solar and batteries etc. I followed the “Home Assistant - Recreate Synergy ‘Home’ Card #184” on here https://github.com/TypQxQ/Sigenergy-Local-Modbus/discussions/184.

I tried to add iFrame which is now read only so tried MMM-iFrame-Ping. As a basic test I tried to display our (Australia) ABC news site and it couldn’t be displayed. I even just tried google in case it couldn’t go in an iFrame and that didn’t pop up either.

I then tried MMM-HomeAssistantDisplay and have managed to get the title Home Assistant up but of course the templates on my code don’t exist, but I wanted to clarify something. For this module, can I display a dashboard, or do I have to build the page with templates. Does each template act like a “card”? I haven’t tried to do anything with templates as yet.

Any pointers? I like the idea of doing both ways, but the first doesn’t work and the second I think I might need to know about templates more.

@British_Kiwi Did you add the iframe statement above to the HA config file? Mentioned in
https://forum.magicmirror.builders/post/128421

I dont have a lot of experience with either approach
I used the sample from HoneAssistantDisplay to build a table of settings

And I just put a dashboard on a pages page w MMM- EmbedUrl
I didn’t size it so it’s just a corner
It didn’t work before adding the iframe stmt to ha config

For the module. I use the programmatic approach
https://github.com/wonderslug/MMM-HomeAssistantDisplay?tab=readme-ov-file#programmatic-sections

Hilt

@British_Kiwi

Try the following :

In your HA configuration.yaml file, include the following

http:
  use_x_frame_options: false

Restart HA first, wait for it to finish, then restart your MM instance to see if the iFrame shows.

If not, give this this older MM module a shot. It’s more straight forward than iFrame Ping and it works with custom button cards ( i use them in my notification area ).

Within HA, you can also make use of the Kiosk Mode HACS add-on to hide the header and/or sidebars. Once installed, you simply add the following at the top of your dashboard YAML using the Raw configuration editor ( this step is shown in the vid ).

kiosk_mode:
  non_admin_settings:
    kiosk: true
    ignore_entity_settings: true

I did have to logon thru the iframe for the dashboard to appear instead of the HA logon panel
the logon persisted across MM startups, at least close in time

the HomeAssistantDisplay module use the api token

@sdetweil and @Hilt

I have made progress (sort of). Before when I was testing the various versions of iFrames I hadn’t even tried linking to HA and was using basic websites and just couldn’t see it.

I commented out the HA Display one for now in case it was all throwing a wobbly and I tested that I could access the HA login screen from the monitor using the browser.

I have used this to add an iFrame with the URL for the HA:

           {
			module: 'iFrame',
			position: "fullscreen_above" ,	// This can be any of the regions.
			classes: "testing",
			config: {
				// See 'Configuration options' for more information.
					url: "http://xxx.xxx.xx.xx:8123/",
					width: "100%", // Optional. Default: 100%
					height: "100vh", //Optional. Default: 100px
					border: "1px",
				},
		},

I can now see it, but I cannot get it to fill the page. It is a very thin window at the top. I have tried changing height to 100%, but found something on the forum about vh. I have tried fullscreen, fullscreen_below and other sections and nothing seems to make it particularly big.

The other thing I have noticed is that on my first page “home” my google calendar is missing, or at least the data has gone. I am using MMM-CalendarExt3 and my Todoist (MMM-Todoist2) list has all gone too. the title is there, but no tasks. I had noticed that the calendar and page indicators etc needed updating so I tried that afterwards, but no luck. Is it because I have multiple places using URLs? The calendar has 5 google calendar’s, though the Todoist is using an API.

Apart from that, it is going well 😂

sdetweil

@British_Kiwi you dont want full screen_above, that puts it on top of every other module, hiding them

Try mmm-embedurl, works for me

British_Kiwi

@sdetweil . I’ll try that tomorrow. Just about to head to bed.

I think I might know why I lost my google calendar in the meantime. I had seen there were updates which I had been ignoring, but in the end i updated the calendar, pages and page indicator. I have since seen that the new MM update has impacts on the calendar and looks like my nodjs was an old version. I followed your instructions from here https://forum.magicmirror.builders/topic/19770/nodejs-version-update-issue/2?_=1759892047767 and have updated nodejs to v 22.18, but I still don’t have any calendars showing.

A problem for another night!

sdetweil

@British_Kiwi if you had used the upgrade script it would have been done for you

Nothing in the MagicMirror upgrade should have affected calendar.

sdetweil

@British_Kiwi MagicMirror is a 3 layer design

Full screen_below on the bottom
Module positions. (These will hide parts of fs_below)
Fullscreen_above on top (this will hide anything below it), great for a security panel when no one is around, for example

Hilt

@British_Kiwi

You can also try placing it bottom right and sizing by pixel count, increasing gradually until you reach your monitors full(ish) resolution

I haven’t tried full screen. But one of my configs looks like this :

                {
                        module: "iFrame",
                        position: "bottom_right",
                        header: "HOUSE STATISTICS",
                        config: {
                                url: "http://192.168.1.4:8123/mm-dash-right",
                                        width: "410px",
                                        height: "215px"
                }
                },

If I increase width, the iframe expands to the left. If I increase height, it expands up. Worth a shot.

@sdetweil and @Hilt

Sam, I usually use your script (not quite sure why I didn’t, blaming lack of sleep). I have run it and all running correctly. keep getting a message about environment variables, but have been running the following code which seems to sort it till the next time.

pm2 restart 0 --update -env

Thanks for giving more details about fullscreen below and above. I don’t have anything else on that page, so I am surprised why this didn’t fill up the screen.

@Hilt I ended up using your code about using bottom_right and after a bit of tweaking and I can now see it. just need to log in.

My main problem now (there is always one) , is that I still can’t get the calendar to populate or todoist. Of course, my last back up was not just before this stopped working and I think it was around the time I updated the module. However, I didn’t update the Todoist module so a bit baffled. I’ll have to check my code and see if I have inadvertently done something. I am using VSCode and doesn’t look like I have, but will go through it carefully after work. Here is what it looks like now:

I do have to tweak my sizing of the modules on my home page as there is a little overlap when everything is populated, but apart from that this page was working well.
Anyway , have a great day :)

sdetweil

@British_Kiwi ok

Calendarext3 gets its events from the default calendar module
Do you have that configured, and does it work?
To
Make it not show just comment out its position using // in front of that line

Now, because ext3 gets events from the default calendar module, and there couple be many individual calendars contributing events, the developer doesn’t want the screen to be flashing for individual updates

So there is a cycle, refresh interval, default 10 minutes
So every 10 minutes the events received since last time will be displayed

Now the first time you don’t want to wait 10 mins
So there is a waitFetch parm, 5 seconds

After 5 seconds, whatever events have arrived will be drawn, even if none, then we wait refreshInterval and do it again

You can increase the waitFetch time, side effect is NO Display til after that time limit

British_Kiwi

@sdetweil the default calendar isn’t working either! I have commented out ext3, I have reduced the calendar entries on the default calendar to just Australian holidays in case Google is having a fit! It just says loading. I had not touched any of this code in the config at all. I have seen there have been cases of calendar’s not loading last January and few again now. Is it worth me raising it on the github discussion or issue list?

https://github.com/MMRIZE/MMM-CalendarExt3/issues ?

sdetweil

@British_Kiwi can you look at the output of npm start to see if an error is reported

British_Kiwi

@sdetweil not sure if I am doing this right. I thought I had made notes about how to check logs etc, but after some googling I have this (which I don’t think you were after):

admin@raspberrypihome:~/MagicMirror $ npm run config:check

Not too sure which module this is referring too.

Here are the pm2 logs. I’ve removed yesterdays stuff. All I have done this morning is pm2 restart 0 --updated-env (as it keeps saying something about environment variables which I haven’t seen prior to a few days ago.

It does it look like there is an issue with a module, but I can’t work out which module. Any ideas on how to work it out?

At the moment I have commented out calendarext3, home assistant display, but I do have iframe showing on one of the pages.

sdetweil

@British_Kiwi if you start a private chat with me, you can paste your config and I will look at it. I agree on the ‘this’ module is unclear!..

sent you a message

@British_Kiwi said in Is adding Home Assistant the right way to go?:

This module configuration contains errors:
undefinedmust be object

accidental extra comma between modules (commented out module, but the trailing comma was on a sep line)

    { 
     module:"foo",
    }.
     .    <--- that guy
    {
      module:"bar",
    }

this is a bug,
opened issue
https://github.com/MagicMirrorOrg/MagicMirror/issues/3910

as a separate way to avoid this, you can add

   disable:true,

after the module: line
to disable a module without having to comment it out

disabled: false,

makes it active again
