Product Specifications Display 7-inch capacitive touchscreen Mounting Style Wall flush (fits standard single-gang electrical box) Input Voltage 120 VAC ±10% Maximum Current 1 A Maximum Ambient Temperature 35°C (95°F) Warranty 3 months 3. Mechanical Installation ⚠️ Important: Electrical work should be performed by a certified electrical technician. Always turn off power at the circuit breaker before installation. Technician Steps (Electrical Wiring) Step 1: Remove the current wall switch(es) and separate the Line (hot) and Neutral wires. Ground connection is not required — the included USB charger has internal protections. Step 2: Connect the USB charger wires: Black → Line (hot), White → Neutral.
Step 3: Connect the short USB cable (provided with HAUI) to the USB charger. Tuck the wires neatly inside the electrical box together with the charger, leaving at least 1 inch of clearance for the HAUI unit to sit flush. User Steps (Final Assembly) Step 4: With power safely restored and wires secured, connect the USB cable to the HAUI display.
Step 5: Align the top of the HAUI interface with the mounting bracket, then gently press the bottom tabs to snap it securely into place.
Step 6: Once the top is aligned, bring the display towards the bracket until the bottom snaps of the bracket engage with the display.
4. Powering Up & Setup Wizard
Once the USB cable is connected and power is applied, the HAUI will automatically boot and launch the Setup Wizard.
Follow the on-screen steps in sequence to configure:
- Wi-Fi connection
- Hostname
- MQTT connection (optional but recommended)
- Backlight control service
MQTT Integration: When connected, MQTT allows Home Assistant to dynamically adjust screen brightness, dim timeout, and sleep timeout. It also provides useful diagnostics (such as undervoltage events) directly in your dashboard.
If MQTT is not configured, the unit will use safe default settings for sleep and dimming behavior.
On the final wizard screen, tap Reboot. The HAUI will restart and load directly into the Home Assistant dashboard URL you entered during setup.
