Flat Display v2 — Capacitive switch with display and humidity sensor, custom design

About the Flat Display v2

Flat Display v2 is a Zennio glass capacitive KNX switch with a 2.4-inch OLED display of 128 × 64 pixels above five touch buttons^[1][2]. The buttons work individually or in pairs, each with its own LED^[2]. The display keeps one permanent page, normal or thermostat, and its built-in character set includes Cyrillic, so labels can be written in Russian^[2].

Touch input can be locked by a binary object or a scene, and the cleaning function ignores touches for a set time so the glass can be wiped without triggering anything^[2]. The beep is disabled by a parameter or an object, and the brightness of the display and LEDs switches between a normal and a night mode^[2]. The built-in sensor measures humidity with ±5% accuracy^[1]; the value goes to the bus, and the switch can report humidity that is too high or too low^[2].

It is powered by the KNX bus alone, up to 17.5 mA at 29 V, and a probe, motion sensors or push buttons are wired to its two inputs^[1]. It fits a square or round back box on the ZACHOLD3 plate supplied, stands 9 mm proud of the wall, and the display must not be pressed while it is fitted^[1]. On the ZVIFDV2C360 version the glass background is fully custom, with logos and lettering^[3].
