The 3 generations of timer switch plug used in my household

Timer switch plug is a kind of gadget that can easily convert a normal wall socket into programmable timer socket. 

I have been using it for quite a long time, from one generation to another.

Some scenarios of using timer switch plug include:

  • To supply electric power to TV and audio-visual devices in the morning, so that they are well standby to be turned on instantly, and to cut off the power at mid-night.
  • To switch off the air purifier when you go to work, and to switch it on when you back home.
  • To turn on the light at night, and turn off in the morning.
  • To turn off the wall charger power 2 hours after charging.
  • etc.
Here are some photos of the 3 generations of them (front view, side view and back view):





Surprisingly, all the 3 generations are selling at almost the same price in the market now.

The 1st generation only support programmable timing interval of 15 seconds time period, and you can decide during that particular 15 seconds it should be turned on or turned off by toggling its key position to be up or down.

It will rotate and repeat its setting every 24 hours. It has no clock to keep track on the actual time. In the event there is a power blackout, it will stop rotating, and therefore after the power resume, its setting will be offset and you might need to readjust its setting.

The 2nd generation, a digital one, is more advanced. It has an internal clock, powered by an internal rechargeable battery, and its programmable period is up to a week.

With this capability, and its programmable timing interval of 1 second, it is possible for you to set it to turn on and turn off at different timing for each day in the week.

The 3rd generation, a smart plug which I am using now, is even more advanced. You need a mobile app (either Smart Life or Tuya Smart) to control it.

The smart plug connects with the corresponding mobile app via 2.4GHz WiFi network that is connected to the Internet. There is a gateway server in the cloud that link it to your mobile app.

One mobile app can be used to control multiple smart plugs.


Scheduling the time for it to be switched on and switched off is a basic function, available in the app.

On top of that, the smart plug also has the capability to monitor and record down the electric power consumption of the devices attached to it.




Together with the sensors in your handphone accessible by the mobile app, it is possible to program for scenario-based automation, such as:
  • Turn off when you are away (your handphone detected location is leaving the smart plug)
  • Turn on when you are back (your handphone detected location is near to the smart plug)
  • Turn on/off at sunrise/sunset, which will be on different timing during different season
  • Turn on/off when it rains (it can get the weather information from your phone)
  • etc.


It even can integrate with some voice control assistants, including Alexa, Google Assistant, SmartThings, IFTTT, etc. so you can actually speak to your voice assistant and ask it to be turned on/off with your voice command.

Converted my Asus RT-AC86U router into AiMesh node and linked it to my new Asus RT-AX86U router to form home AiMesh system

Recently, I purchased a new Asus RT-AX86U router to replace my 4-years-old Asus RT-AC86U router. The main reason being I want to take advantage of the RT-AX86U's WiFi AX (a.k.a. WiFi 6) capability for some of the newer devices in my household.

What should I do with my old Asus RT-AC86U router after I have successfully replaced it? Well, I converted it into an AiMesh node to form a stronger, stabler home WiFi with larger coverage area, by creating an AiMesh system with the 2 routers.

Initially, I faced difficulty in getting my RT-AX86U to discover my RT-AC86U AiMesh node via wireless network, in order to add it into my home AiMesh system. I managed to resolve the issue by using a network cable.

Here are the steps to form an AiMesh system, with RT-AX86U as the AiMesh router, and RT-AC86U as the AiMesh node.

  • Make sure both the routers have already been updated to the latest firmware version. I am using  AsusWRT-Merlin firmware for both the routers, and the current latest version for both of them is 386.5_2.
  • Use a network cable to connect your PC or laptop to one of the LAN ports of the old RT-AC86U router. This is for you to use your browser to access the router's configuration web interface. Alternatively, you can also use WiFi connection to access the router's configuration.
  • Go to Administration > Operation Mode and select AiMesh Node. Click the Save button to confirm your selection.

  • Wait for your router to reset and restart itself into an AiMesh node, ready to join an AiMesh network.
  • Use your network cable to connect the WAN port of your AiMesh node directly to one of the LAN port of your AiMesh router.
  • Now, login to the configuration web interface of the AiMesh router, which should be the new router that links your home network to the Internet.
  • Click on the AiMesh button at the bottom of the Network Map page. The right panel will switch to AiMesh function.

  • Click on the Search button to search for your AiMesh node.
  • You should be able to find the old router as the search result almost immediately. If you don't use a network cable to join the routers together, but trying to use wireless connection instead, you might have trouble in finding the AiMesh node.
  • Follow the screen instruction to setup your AiMesh system. This process will take some time (about 1-2 minutes).
  • Once the AiMesh system is successfully established, you will be able to see the content inside the AiMesh function of the new router.
  • Congratulations. If you reach this step, your AiMesh system should be established. Now you can remove the network cable joining the 2 routers, and they should continue to link up with each other using WiFi connection.
  • Put your AiMesh node router to the location where you want to place it, and you are done.
You might want to configure your DHCP to give a fixed internal IP address to your AiMesh node router. You can find out its MAC address used to join the AiMesh system by clicking on its icon under the "List of AiMesh nodes in your AiMesh system" section, then click on More Config.

In future, you can update the latest firmware to your AiMesh node(s) from the AiMesh router's configuration page, under Adminstration > Firmware Upgrade.
