I did a similar setup with another Homey App and an API endpoint (instead of MQTT): Local API | Homey
Setup Actions (Tested with my small Shelly Wall Displays)
Configure URL and “command”
And afterwards you can use a Flow to run commands per action:
thx Andi! you’re too fast with bug fixing 
Energy Device Tab → works
Camera on/off toggle → works
quick filter → works
hamburger room select (requested via github) → works
Danke!
Hi Andi
Quick Question → is it possible to have a “then” card for the wall display to show a device?
E.g. if the doorbell is activated (in my case a shelly 1pm) THEN open my unifi camera device on the wall display. this would always show me on the walldisplay (near the entry) if someone rings the bell who the person is) 
(i guess live stream is not possible, currently i get the latest picture with the unifi cam)
Great news — this is now implemented in v1.3.50!
A new Flow action card is available: “Show camera on dashboard”
How it works:
When the Flow triggers, the dashboard will automatically open the camera snapshot modal on the selected display(s). No manual interaction needed.
Example Flow: When Shelly 1PM (doorbell) turns on → Then Show Unifi Camera on Entry Display
Note: The snapshot shown is the latest image from the camera — live streaming depends on the camera app (Unifi in your case). But it pops up automatically so you can immediately see who’s at the door!
13h ago the request - 7h later the solution… Kudos my friend
Works smoothly
Hi!
Sorry, I had to return it. The Shelly Wall Display XL is a terrible piece of hardware. I have no idea how a device with such a laggy UI is released and sold at a premium price in 2026.
I have no bad words about the app, but holy cow what a terrible device.
Hi Andi
Some usecases are just popping up in my mind during “daily life”. would it be possible to have a feature like “messages” on the walldisplay? e.g. i need a reminder for something (take out the trash / robot vacuum needs cleaning / …). like a message popup which you can send to your display. could be like a modal or popup. also with the function that it will disapear after x min.
Hi Rick - As I’m on a short summer break soon, could you please open it as an issue on github?

Thank you
Can I delete the room names on a shelly x2i and see only devices for a cleaner look ?
Hi,
Big thanks already for this app, really appreciated is everything i was looking for.
still have one issue/question:trying to understand the energy dashboard:
while i check the real situation:
in the homey app, the data is also same is the real situation
can you explain me why house says 10? seems like its making the sum, but that isnt what it should do?
thanks already for the feedback
Looks fine as long there is no solar production - right?
Open the Meter device in the Homey app during solar production and check the live measure_power value — does it show positive or negative when you’re actually exporting to the grid?
If it always stays positive, I’ll need to add alternative direction detection in the dashboard (e.g., derive the sign from the meter_power.imported vs meter_power.exported delta).
well i don’t think its looks fine even without solar productions, because as you see here
my house is asking 0.70kw , and that import is coming from the battery.
So i am not taking 0,70 from the grid and 0,70 from the battery, it just 0;70 from the battery that i am using atm for my house
so the 1.50 he shows is wrong, the house should show 0,70
i hope it makes sense what i am trying to explain.
Hi Wesley - Please try the new TEST version: Shelly Wall Display Dashboard | Homey
Hi Andi,
This looks really interesting. I’ve tried it through the web browser, and I’m considering getting a Shelly Wall Display (4") for my home office. However, there are a few things that feel a little “clunky” to me, so I’m not entirely sure whether I should invest in one.
Light controls
I’m testing this on my tablet (which is probably the closest I can get to the Shelly touch experience without actually having a Shelly), and I find the dimmer slider quite frustrating. Quite often, the light turns off or on when I’m simply trying to dim it, because I haven’t touched the slider precisely enough. On a small 4" screen, I imagine this could be an even bigger challenge.
Blind controls
Some of my blinds, which are integrated through the Bond Bridge app, show sliders on their tiles, similar to light dimmers. However, the Bond app doesn’t actually allow the blinds to be set to a specific position (although they actually can through the original blinds app).
I know this is an issue with the Bond app, but with a standard Homey device tile I can choose the control method, including both a slider and up/down/stop controls. It looks like this isn’t currently possible in your app, as only the slider is shown by default. As a result, I literally can’t control those blinds from your app because they only work properly with up/down/stop controls.
I also have another set of outdoor blinds that don’t show a slider, but controlling them is still quite unintuitive. Tapping the tile acts as a toggle: tap it once and the blind starts opening/closing, tap it again and the motor reverses. To stop it, I have to aim for a small stop button in the top-right corner.
Information displayed on tiles
Maybe I’ve missed a setting, but there’s some information on the tiles that feels unnecessary and, at least for me, just adds clutter. For example, some of my lights report power consumption in watts, and that information is displayed directly on the tile. I personally have very little use for that information.
I understand that standard Homey tiles do something similar, but they can be displayed in “compact” mode, where this kind of additional information is hidden.
Tile shape
Some tiles are square, while others are rectangular (taller than their width). This may just be an issue with the browser version, as in the photo from your first post the tiles all appear to be square (except camera ones that don’t have extra informtion). I also tried the “height same as width” option, but it doesn’t seem to make the tiles completely square.
Please don’t take any of this as criticism. I think it’s great that an app like this exists, especially since both Athom and Shelly seem to be too lazy to create an official solution.
That said, have you considered following the official Homey design guidelines more closely? For example:
Adopting the familiar Homey style controls would also mean users wouldn’t have to learn two different interaction methods depending on whether they’re using Homey normally or your app.
Again, great work, and thanks for creating the app! I’m really interested in it and will follow closely to see how it develops.
Cheers,
Alex
Hi Andi,
Works great for me!
The one thing I’m missing though - to be able to display widgets from Homey. I am using Calendar-cloud app which lets me display a widget with my calendar on Homey dashboard, would be awesome to show it on shelly wall display as well.
