Hey community,
Is there a way to get a direct URL to access the details of an entity?
The URL https://my-homeassistant-instance.com/lovelace/entity/sensor.room_temperature
Would open this or a similar view:
This would be useful for all kinds of notifications, markdown content, alerting, etc.
If not possible atm I would go as far and raise a feature request on GitHub.
Do you know of anything? Cheers
If you use the companion app for notifications and if you have an android phone then you can do this. See here for how.
Thereās no generic link though. As you can see in the documentation I linked its not even a real URL, its basically a special command the android app understands.
I think thereās also a way to make a link to show the more info of an entity in a markdown card that I vaguely recall seeing before but I canāt remember how to do it. If you searched this forum I bet its on here somewhere.
Feature requests belong here, not on github. Thatās how this project is managed.
Thanks,
I recall the android action, yes sadly it doesnāt help here. Iāve just searched for anything related to markdown, however couldnāt find anything either. Iāve investigated the different areas of the Home Assistant UI (lovelace, developer tools > states, settings), there doesnāt seem to be a preexisting option (at least it is not used as far as I can see).
REST APIs return JSON. Not really the same thing.
Fwiw @ThomDietrich I canāt find the markdown thing either. Maybe I just imagined it. Sorry about that.

You can get the link by right clicking on the show more(mehr anzeigen in the image in post before mine)
It can be logbook instead of history
its a shame you canāt use the āmā shortcut though
Indeed! That is a good discovery.
Sadly still doesnāt solve my use case as I want to be able to control and manage the entity after following the linkā¦
Hmm you could potentially go straight to the devices pageā¦ Itās just a url.
The popup window is different because itās a popupā¦
http://homeassstant:8123/config/devices/device/deviceIDorsoemthign
Although at that point you could also go to a lovelace viewā¦
Good idea, sadly I have an entity_id, not a device :-/
I think there are ways to programmatically identify the device an entity belongs. That would be a solution for meā¦ if every entity indeed belonged to a device, which isnāt the case 
Thanks for all your suggestions! Feels like this is indeed not solved yet. If you believe it shouldn please Vote on this feature request 
hmm not sure I see the use-case honestly.
If it doesnāt have a deviceā¦ make it a device?
It looks like a mqtt sensor, just make it auto discovery one, you will be able to link to the device page.
Or just set up what you want to see on a lovelace view and look at that
alert rpi is hot
goto
rpi-lovelace (view graphā¦Turn on server room fan)
you could even start hereā¦
editā¦ you are basically requesting a deep link to developer state pageā¦ seems counter productive when you could actually make a nice lovelace view with all the info from different entities you want.
This went a bit off-topic. Yes your workaround would be a solution if all entities had a device and hopefully, eventually, the Home Assistant world will have matured that far. However clearly this shouldnāt block short-term quick wins. Letās put your devices idea to the side for a second.
Even if there was an over-engineered workaround (devices, custom lovelace ui, some custom component, ā¦), thatās hardly an adequate solution. The original request was for a āDirect URL to entity detailsā. I can think of numerous use cases why something as simple as that makes sense. I will intentionally only list one (not mine, but probably the one everyone can relate to):
āHey Admin, I had to realize that this switch doesnāt work anymore. Could you have a look? Thanksā
I am the adminā¦ in this case, as I look after the entities and home assistant.
I wouldnāt want to link this externally to say github, I would link to whatever the entity relates to eg. mosquitto or an addon.
on the other handā¦ my wife wouldnāt link it to me either. She would say the tv isnāt working you broke it again.
in fact she has limited access to this area as I wouldnāt want her to rename things etc.
She has her own lovelace page with stuff she uses.
Iām pretty sure theyāre envisioning HA sending you (the admin) a notification with that link. Like if say a switch became unavailable for 5 minutes HA would send the admin of the system a notification like this
āHey Admin, I had to realize that this switch doesnāt work anymore. Could you have a look? Thanksā
With a link that takes you to the more info view of the entity. To see when it broke and possibly fix it.
Or at least follow other links to fix it in the related tab. Not much fixing can be done from the more info popup unless the problem is that the name or icon changed randomly.
Yeah i did get that impressionā¦
It is sort of an compelling argumentā¦
Except
It only applies to manual entities as the others can in theory do thisā¦
if they are manual entitiesā¦ Send me the yaml lol, assuming I was remote and not getting yelled at.
it would be from an admin account to admin account. Non admins donāt have access to developers/states. I actually have to check that, it has been ages since I logged into my wifeās account.
non admins are going to see the entity in lovelave to even notice it is brokenā¦ They could link the lovelace urlā¦ Or yell at me.
non admins like my kids shouldnāt be near stuff they can break.
any other reasons seem like they could be automated anyway
I certainly wouldnāt link an entity externally, even if someone else could log in.
I totally vote for this feature.
This could be implemented as an extension of the default action framework.
Basically to add an entry so that, when āmore-infoā or ātoggleā, an attribute with the target entity for such actions can be defined.
By adding that, then thereās multiple ways to use that across Home Assistant, supporting hopefully OP use case and many more like post 84631 or 160476
Thanks!
These can already be done without this feature request. The posts have the answers in them.
84631 how-to-create-a-button-linking-to-another-ha-tab-or-view
160476 open-more-info-of-an-other-entity-climate-at-tap-on-a-glace-temp-sensor
Fair enough for the 84631 is slightly out of topic, but 160476 is a HACS solution, and is not a complete one as it only works on browser that have been āregisteredā, which is a browsermod only thingy.
The idea here would be to be able to develop a more-info home assistant standard action that instead of the parent entity opens another entity more-info popup. With the āproposalā in the other thread the answers need to go device per device enabling the solution which creates a dependency on its implementation and is not scalable. Imagine all hass solutions required you to rework them for every single device accessing the lovelace dashboards!
So still thinking that should be solved through new feature only.
Just an FYI, this request is about being able to send someone a URL that when followed opens HA with a more-info pop-up of a particular entity in focus.
So Iām not entirely sure how actions in a card in a dashboard are related. You can certainly put a button in an HA dashboard that opens more-info or a particular dashboard/panel, thatās not what this is about.
This is about HA sending you a text message or something with a link. Receiving that link on some random non-HA channel and following it to a more-info pop-up.
Right. So like see here a link wouldāve been really handy. Like the whole URL instead of just the random number at the endā¦
EDIT: Iām realizing this may have been you making a point. Like this is what we have to do today (text an entity ID to copy and paste) instead of sending a nice link. If so, props.
What advantage does the url achieve here though(if it doesnāt exist). I could already link to something in my tap action. I may have to make it and it wouldnāt be scalable sure. I also donāt need someone to send me a link.
They can send the friendly name or entity_id and I can find what I need for debugging.
If it is for the intent of sending debug information to an external Adminā¦ then to who and how much are they charging to supply a support and helpdesk feature?
The feature request could be ā¦ make custom-card an inbuilt-card. Pretty sure that has been covered.
It also goes back to my point of most of this request can already be done in lovelace.

@CentralCommand I was trying to avoid your edit of the link tooā¦
Although enough info was actually given for me to quickly find it tooā¦
Here is something that helped me Introduction | Home Assistant Companion Docs
The companion app on Android supports entityId:... URLs which do exactly what this topic is about - opens the specific entity more-info dialog in the app. Unfortunately itās not a fully qualified URL like some people here are asking for but Iām sure itās going to be good enough for some of you.
