After installing the smart speaker, I found that the socket is behind the sofa! Or the speaker can only be placed in a corner! The whole house WiFi is dead, and the surveillance camera is frequently disconnected; the whole house intelligence is not sensitive, no response, and the scene is not executed; the smart installation is not working well, and I want to change it back to the ordinary one, but I found that there is no control line at all and it cannot be changed! These rollover scenes are staged every day; smart home cannot be achieved by buying a few devices, and the core secret is hidden in the wiring planning in the early stage of decoration.
The three core layouts that must be done in the water and electricity stage, 80% of families will miss them;
- The whole house zero line is the lifeblood of the whole house smart lighting system! Traditional wiring only leaves the live wire, and the later installation of smart switches can only choose the high-priced single live version (poor stability + doubled cost). Be sure to ask the electrician to leave the zero line for all the lamps in the house so that it can be upgraded without loss in the future.
- No matter which wireless smart device you choose, just follow the original wiring and add a neutral line in the bottom box; in case you don’t want to install smart devices later, or feel that it is useless and want to change back to ordinary switches, you can only change back if there are control lines and dual control lines; if the smart brand you choose is the kind that only needs neutral and live wires for all switches, it is still safest to follow the original wiring;
- Network cable solution
a) Put the main router + AC controller in the weak current box, and pre-bury Category 6 network cables in each room. Pre-bury 2 cables in the living room, one for the TV and one for the AP panel; in areas with water stains in the kitchen and bathroom, you can reserve network cables on the opposite wall. There is no pressure for WIFI to pass through a wall, so that the whole house WIFI network can be covered without dead angles, and the roaming delay is <10ms. The WIFI AP panel can be selected as a dual-band gigabit.
b) Reserve an extra network cable in the central air conditioner in the living room. The smart home central control host will have a better signal if placed here;
- Fiber optic solution: Pull single-mode fiber from the weak current box to the TV wall or the room where NAS is arranged, which can support future 10G transmission. This is suitable for homes with high network requirements, and it is not necessary for ordinary families.
- Socket curtains: Reserve five holes on the top of the curtain motor and a splash-proof socket next to the toilet (smart toilet cover + mobile phone charging); remember: it is better to leave more than less, and the smart socket can directly replace the original socket.
- Wired smart home: KNX and 485 can be arranged directly in a professional store; PLC wiring sounds simple, but it is actually quite troublesome; IV. Security system 1. The ultimate solution for monitoring power supply: Don't use a plug for the camera! Pre-buried POE power supply network cable in the ceiling (one cable transmits data + power supply at the same time), which is beautiful and beautiful.
Sensor wiring:
a) Human motion sensor, human radar wave
b) If a gas alarm is installed, the power cable is pre-buried in the kitchen ceiling, and the sensor is installed 30cm from the top (natural gas is lighter than air). If you install a water sensor, it is best to leave a socket in the cabinet so that the wires can be hidden and look more beautiful.
For air conditioners, floor heating, fresh air central air conditioners, Japanese ones generally do not need special wiring, and can be directly installed with a home controller. For other brands, you can ask the air conditioner construction party to connect a shielded wire from the external unit to the adjacent internal unit; Appendix:
- The distance between strong and weak electric pipes must be >30cm! Wrap tin foil at the intersection, otherwise the smart device will ventilate intermittently
- Do not put the weak current box in the smart gateway! The best location is in the geometric center of the house (in the living room ceiling)
- Wiring is the focus of smart home
