OLED LED Hygro MCU

An “app call” = a command sent from the phone, through the cloud + bridge, into the Onyx’s firmware. Every upgrade below rides this same path.

The four upgrades

1
OLED screen synced with LEDs
One app call sets a look, and the screen + lighting move together (matched color / theme), instead of being controlled separately.

★ NEED THIS 2
Push hygrometer seasoning via app call
Send a seasoning routine from the phone — the hygrometer runs the guided humidity ramp on its own. No manual on-device setup.

Always-on / sensor-activated hygrometer
Choose continuous readings, or have the sensor wake on activity (lid open / motion) to save power — selectable behavior.

Upgradable firmware with headroom
Over-the-air firmware updates, plus spare memory + compute so future features can be added after units ship.

Where each change lives: App Firmware Hardware / BOM (greyed = not affected)
★ Item 2 (push seasoning) is the must-have for this reorder. Items 3 & 4 carry hardware/BOM implications — confirm cost before locking the run.
