easy to read

Small in size but easy to read. Effective and aesthetic. The smpl mini display has an e-ink display with a 264 x 176 resolution which makes it easy to read even in direct sunlight, evening lightning and from across the room.

flexible design

A versatile magnetic wall-mount gives optimum flexibility. The smpl mini display is easy to place elsewhere temporarily and effortless to replace the battery. You decide whether it should be placed horizontally or vertically.

Got a question?

Only a pairing button is implemented in this first version to keep cost down and to keep the device as simple as possible. There are also a lot of switches and buttons around in people’s homes already. But something we will consider for the future.

The primary idea is a flexible device that can be placed anywhere. Mains power will make the unit dependent on electrical outlets. And adding a dual power option will increase the cost and make the device too thick.

We have chosen two CR2450 button cell batteries and very efficient power management to have maximum battery lifetime. Based on tests with minute-by-minute updating we estimate several months battery lifetime.

Using high quality batteries and having an optimized Zigbee network will ensure maximum lifetime. You can furthermore dramatically increase battery lifetime by manually decreasing the update frequency as well as utilize the pause/resume flowcards. This will easily give you 6 months or more.

Homey is the most versatile and user-friendly smart home hub on the market. We are Homey enthusiasts and have developed the smpl mini display based on feedback from the Homey Community Forum.

Electronic Paper Displays (EPD) offers numerous advantages over both TFT and OLED. Especially when it comes to power consumption where it outperforms massively. This is because it only draws power when refreshed or the content of the screen is changed. And power efficiency is crucial when the display is battery powered. It’s clear readability in direct sunlight also makes it ideal for information display indoors.
