OneHome Smart Panel installation

Time: ~60–90 minutes 

What you’ll need

  • Phillips screwdriver, level, pencil, utility knife

  • Voltage tester (non-contact)

  • Wire strippers

  • U.S. single-gang old-work box (if adding a new location)

  • 120V AC supply (hot/neutral/ground) in the box

  • Optional: Cat5e/Cat6 LAN cable, low-voltage speaker wires (14–16 AWG) to your ceiling speakers

Safety first: Turn off the breaker and verify power is off with a tester. Follow local code/NEC. If you’re not sure—hire a licensed electrician.

Step 1 — Plan the location (2–5 min)

  • Choose an eye-level spot (typically 48–54 in from floor).

  • Avoid direct sunlight and high humidity (don’t install in bathrooms).

  • If using wired speakers or LAN, confirm those cables can reach this box.

Pro tip: Center the panel near the main living area so scenes are one tap away.


Step 2 — Install or prep the wall box (10–20 min)

If you already have a U.S. single-gang box:

  • Remove the faceplate, gently pull wires forward, confirm hot is off.

If you’re adding a new box:

  1. Trace the old-work box template and cut the drywall opening.

  2. Pull 120V cable into the opening (hot/neutral/ground).

  3. (Optional) Pull Cat5e/Cat6 for LAN and speaker wires (14–16 AWG) for multiroom audio.

  4. Secure the old-work box per manufacturer instructions (flip-out ears snug, not over-tight).


Step 3 — Make the electrical connections (10–15 min)

Always with the breaker OFF.

  • Connect hot (black) → panel line, neutral (white) → panel neutral, ground (green/bare) → panel ground using listed connectors.

  • (Optional) Plug in RJ45 LAN for the most reliable network.

  • (Optional) Land speaker wires to the panel’s speaker terminals (observe polarity + / −).

  • Dress wires neatly so the panel sits flush.

Do not feed PoE into the LAN port. The panel is 120V AC powered (100–240V compatible).


Step 4 — Mount the panel (5–10 min)

  • Align the panel’s mounting plate to the box; level it.

  • Fasten screws until snug (don’t overtighten).

  • Attach the panel to the plate (hooks/clicks depending on model) until it’s secure and flush.


Step 5 — Power on & basic setup (10–15 min)

  1. Restore power at the breaker; the panel boots up.

  2. Follow the on-screen guide to join 2.4 GHz Wi-Fi or confirm LAN.

  3. Log in to the OneHome / Tuya / Smart Life app.

  4. Add devices (lights, switches, sensors, curtains) and assign rooms/zones.

  5. Create your first scenes (e.g., Morning, Movie, Goodnight).

Pro tip: If you have voice assistants, enable Alexa/Google and link scenes for hands-free control.
