On the device details only the sensor value (and the unit) are shown because a limit amount of characters. Because it is for demo purposes we haven’t include icons.
When switching display layouts the values are updated directly but are read from Homey on an minute to minute interval. So the values are visible on the screen within a minute at most. The screen does not update when the value of the sensor are unchanged.
Looks nice. Somewhere i can register for pre-order notice?
Thank you. We are working on something like that, we will announce when this is ready here in this topic.
Keep us posted…
OMG! I need this!!!
Any indication on a release? (Q2, Q3, Q4, 2023)
Bump
Bump?
In best case late Q2. But most likely in the beginning of Q3.
SIGN UP IS READY 
We have just launched our product web page including sign up, so you can be among the first to know, when the smpl mini display is ready to order: https://www.smplproducts.com
Some delay due to the war in Ukraine
It has taken a bit longer than anticipated to build the device. The smpl mini display is developed by the Danish tech start-up Martins Tech Garage who has assembled a team of European specialists; EKTOS/TECHTO and Koktail.
Our awesome hardware team is situated in Ukraine. The development division was originally placed in Kharkiv, which is situated in the Eastern part of the country only 30 km from the Russian boarder. Kharkiv is one of the cities in Ukraine that has been under constant bombardments from the Russian forces since the start of the invasion. Our test set-up and earliest prototypes was lost and is being re-built in the manufacturing site which is placed in Ivano-Frankivsk in the Western part of Ukraine – far from the front line.
It is very important for Ukraine to keep business running. EKTOS/TECHTO is already back at 90% capacity after successfully moving their development division, equipment and team members including families from East to West. And some women and children to the head quarter in Denmark. The management at EKTOS/TECHTO has handled the situation absolutely fantastic and the team members has shown super-human strength dealing with the terrible actions against their country.

Hi All,
I have just released a new version of the app:
v1.1.0 Feature: add Homey logic as sensor source
Change log:
Do you have any updates for us? 
Bump
Hi all.
Sorry for the long silence.
We are currently testing the first prototype for the device and improving stability and battery performance on each iteration.
UPDATE: FUNCTIONAL PROTOTYPE TESTING. SCHEDULED PRODUCTION
I am thrilled to share that we have finalized electronics including EMC testing etc. to pass CE marking. After several prototype iterations, the final mechanical as well as enclosure design is ready and plastic molds are in production. All components for the first production batch are secured (ordered/delivered).
We are currently doing extensive testing on fully functional prototypes:
What is currently working?
After installing the smpl app, the on-screen and in-app pairing instructions easily connects the display to Homey which then awaits the first data instructions. Then, creating a display layout in the smpl app and a flow to push the layout to the desired display, will start the data push. All sensor templates are now updated once per minute, if data has changed, as a standard.
Pushing the back-button on the display once, will change orientation (portrait/landscape), twice will change the theme (positive/negative) and three times will show a service screen with battery status and release numbers etc. A long press will pair/un-pair the device.
Currently there are 50 different icons to choose from. And three different data types (numeric, boolean and enum/text). The app supports data from Homey device capabilities (sensor values from your installed devices) as well as Homey logic variables (your own list). The device capabilities screen of the display in Homey will show the current display layout including icons and live data of the selected sensor templates. Battery level is also included in Homey. A trend indicator and a recent update indicator has also been implemented as on-screen graphics. The trend indicator will show a small up or down arrow for numeric values. And the recent update indicator will show a small dot to indicate if the data has been updated since last update cycle.
What is next?
Everything now works as intended. And production planning is in process. Scheduled production is August/September.
Further firmware and app development before production includes e.g.:
Remember that you can test the app and a virtual display already now by installing the most recent release of the smpl app in the Homey app store: smpl App til Homey | Homey 6.

Can’t wait 
I started to experiment with demo display. Looks good.
I was wondering if a dim value can be displayed as real percentage.
A dim value has range 0-1.0. So f.i. value 0.1 is 10% and value 1.0 is 100%.
Is it possible to multiply the dim value with 100 before displaying?
In my opinion, you should do this in a calculation flow that puts the result in a variable, then display the result on the SMPL display. It’s not the job of the display to do this kind of thing.
Thank you. I already thought of that solution, but it means extra variables and flows to solve something which I think could be a nice feature for this display. The “dim” capability is a standard homey capability with standarized behaviour. Maybe something to consider in the future to have some built in formatting…. 
Here is a demo of the device:
