Typical time

  1. 01

    Home Theater Audio Cutting Out or Dropping

    Photograph the back of the receiver, then unplug and re-seat every HDMI cable; a half-seated ARC cable is the most common cause of drop-outs.

    easy 30–90 min· $10–30 for an HDMI cable or banana plugs

  2. 02

    Security Camera Night Vision Is Blurry or Washed Out

    Look at the night image first: a milky glow all over is reflection off the lens cover; bright streaks are a web or a raindrop; one bright corner is a nearby surface bouncing infrared.

    easy 15–45 min· $5–15 for cleaner and spray; $20–40 for an IR illuminator

  3. 03

    Security camera sending constant false motion alerts

    Open the app's activity history and note what triggered the last twenty alerts; the pattern — headlights, a branch, a spider at night — tells you which fix to apply.

    easy 20–60 min· $0

  4. 04

    Smart Doorbell Not Connecting to WiFi

    Stand at the front door with your phone on Wi-Fi only and run a speed test; below about 5 Mbps up, or one bar, the doorbell will never hold a stream.

    easy 30–90 min· $30–80 for an extender or mesh node; $15–25 for a transformer

  5. 05

    Smart doorbell not ringing

    Test each layer separately: press the button and check the app's event log — if the press is logged but nothing rings, it is a chime or notification setting; if nothing is logged, it is power or Wi-Fi.

    easy 20–60 min· $0 for settings; $30–50 for a plug-in chime

  6. 06

    Smart Garage Opener Not Syncing

    Test the layers: the wall button works, so the door is fine — the problem is between the hub or opener radio, the Wi-Fi and the app.

    easy 20–60 min· $0 for settings; $30–80 for a mesh node

  7. 07

    Smart Lock Battery Draining Too Fast

    Close the door and turn the thumb-turn by hand: it should move freely with no rub. If it drags, the strike plate is out of line and the motor is straining on every cycle — that is the battery drain.

    easy 20–45 min· $5–15 in batteries and screws

  8. 08

    Smart lock not responding

    Use the physical key or the keypad first so you are not locked out, then work through the layers: batteries, radio, mechanics, pairing.

    easy 15–45 min· $5–15 in batteries

  9. 09

    Smart thermostat short-cycling the HVAC

    Photograph the wires on the thermostat base before touching anything and switch the HVAC off at the breaker.

    moderate 30–90 min· $15–30 for a C-wire adapter

  10. 10

    Smart thermostat won't connect to WiFi

    Stand next to the thermostat with your phone on Wi-Fi and run a speed test; below two bars the thermostat will keep dropping off.

    easy 20–60 min· $0 for settings; $30–80 for a mesh node

  11. 11

    Wi-Fi dead zones in your home

    Walk the house with a Wi-Fi analyser and note the signal in each room; you are mapping which walls block it, not just where it is weak.

    easy 1–2 h· $100–300 for a mesh kit
