Received mine yesterday. Works pretty well.
What i’m missing ist extra symbols. Any idea to add own symbols? Like a door, a window or a shutter?
Thanks

Great that you are happy with your new display.
It is not possible to add extra icons or other graphic elements.
Zigbee (or any other low power wireless protocol) has very low bandwith and is therefore not suitable for broadcasting graphics.
This is why graphics is hardcoded in the firmware and is part of the data request from Homey. The only way to add anything is via a firmware update which also has to be supported in the Homey app.
Currently Homey doesn’t support OTA (over-the-air) firmware updates. So in principle it is not possible to update the firmware on our display. We have though included a micro-usb on the board which could connect to a computer for updating. This requires disassembling the device (opening the enclosure) and is only for potential critical issues.
does it work on homey 2023 already? I cannot pair it to homey, just hangs and time outs?
Thanks for the answer.
I have a problem that display is not showing correcly in landscape mode, see picture.
Any idea how i can fix this? Changing screen definition for symbols dont fix the problem.

There is nothing wrong with your display. It is working as planned.
All graphics (icons, fonts, sizes) and their relative positions are hard coded in the firmware on our display. This is the only way to make a display work using low power and low bandwith wireless protocols such as Zigbee.
No graphics are broadcasted from Homey to the display. Only commands what on-board graphics to show and the position.
Data is divided into three different categories: numeric (numbers), boolean (yes/no) and enumeric (text).
Only numbers have a unit attached to the value. Both boolean and enumeric are pure text values.
Due to space restrictions, it was decided from a design perspective to disregard from showing the icon for boolean and enumeric values in landscape, to make room for more text and in a bigger font size.
I might very well have been a wrong decision.
It also seems like the values (‘ZU’) in landscape is placed slightly too high from the description (‘garage’ and ‘kloofenster’).
Both issues are something we will consider for a future firmware update.
Sorry for the inconvenience.
And I hope you are still happy with your new display.
Are there plans for OTA updates via Homey? Like is it being prepared or does Athom don’t have plans yet to support this.

The Homey 2023 firmware is still experimental and not fully developed. The Zigbee firmware on H23 does not support pairing with the smpl mini display yet.
We will keep testing and will communicate when it is supported.

OTA is in theory possible with the Zigbee firmware but no-one has implemented it. So maybe it isn’t, and thats a big guess.
OTA over Zigbee is a technology that isn’t efficient because of the bandwidth and there are better alternatives developed over the years.

works well on HA zigbee2mqtt, it takes 15 min but is ok and not an issue when it is stable . perfect for tuya devices.

Upgraded to Homey Pro 2023 yesterday and the smpl display does no longer work even if it says compatible with the new Homey Pro. First tried to repair, than a complete reinstall of smpl app, but could not get it to pair. Homey Pro 2023 are shipping in big numbers now, so I hope this issue will be fixed soon.

Calling all users 
We are planning a minor firmware and app update to deliver on some of your feedback. Stay tuned! 
We might have room for a few more icons. And are open for suggestions without any promises.
What icon(s) are you missing and for what use-case?

Here the same. Today I received my new display. I got it paired with my homey 2023. It is also switching from 1 to 4 ‘fields’ but not more than that. No numbers or text. Can you give more info when you expect this display to work with homey 2023? Many thanks in advance for the info!
I have a problem that my smpl display doesnt updiate sins some days ago.
Ive tried to restart the app and i have tried to restart homey, but nothing helps.
Any ideas what i can try?
Hi Rikard. Great to reach out to the community. You are also welcome to contact support: Device manual - The smpl mini display
Any ETA for getting this to work with 2023 pro? I got it paired ok, but it’s not showing anything on screen except the text that I got it paired. Response within homey is OK with battery life etc.

No ETA yet.
A HP2023 will finally arrive in Ukraine tomorrow (Tuesday 25th April) for the hardware team to perform different tests and report back to Athom.

same here, haven’t updated in over a month. Absolutely no response, won’t even power off after pulling the batteries. No way to reset it.
After changing battery my smpl worked again.
A litte bit annoying that the battery never hade less than 100% in the homey app.

Hi Adam.
You received a pre-production unit together with other community developers last year before official launch.
I never heard from you again.
Great to know that it has worked for you. Please share more as agreed.
I don’t know if you have updated the firmware? If not, you are running an old version without factory reset option.
You cannot see an e-ink screen ‘power off’. The graphics stay the same. That’s the nature (and advantage) of e-ink.
Sorry about that. We will evaluate the battery level algorythm in a next fw version. It will always be an estimate, but should be better than that.
