Hermai is a minimalist companion app for TRMNL e-ink device owners. Named after the ancient Greek inscribed stone pillars that displayed information at crossroads, Hermai brings calm, focused device management to your pocket. See your fleet at a glance View all your TRMNL devices in one place. Each device card shows its name, status, battery level, WiFi strength, and a thumbnail of what's currently on screen — so you know everything is running without opening a browser. Inspect any device in detail Tap into a device to see its full profile: firmware version, MAC address, signal quality, refresh rate, battery voltage, and Developer Edition status. The current display section shows a large preview of exactly what your TRMNL is showing right now. Set up devices and retrieve API keys Select your device model and provision it directly from the app. Once set up, your Device API Key is stored securely and ready to copy with a single tap. Preview your screens See what each device is displaying without advancing the playlist. The current screen preview loads the live image from your device so you can inspect e-ink rendering on the go. Built for developers Quick access to Device API Keys, Friendly IDs, and MAC addresses. Everything a Developer Edition user needs to integrate, debug, and manage their TRMNL setup. Private by design Hermai has no backend server. Your API keys are stored exclusively on your device using iOS Keychain, never transmitted anywhere except directly to the TRMNL API. No analytics, no tracking, no cloud sync. Logout erases everything. Calm technology No push notifications. No badges. No urgency. Just pull-to-refresh when you want. A monochrome, e-ink-inspired interface that respects your attention — just like TRMNL itself.
