## What is FMCU?

FMCU Button of the Cowards is the ideal button for those (like me) who do not dare to make a physical one. It makes it easy to control your lab remotely using MQTT. Enter your Lab ID once, then tap the toggle button to send messages over MQTT.

• Instant feedback
	•	Connection status indicator
	•	Lab online/offline indicator
	•	Haptic and system-click audio on tap

• Built-in countdown
	•	Shows time remaining until your lab session expires (12 hours from last ON)

• Simple configuration
	•	Store your Lab ID in a dedicated settings page

FMCU is a straightforward companion for any FMCU-enabled lab or person.
