way while the network crashes, you won't be able to communicate with the switches. The daily programs will continue to work regardless.

Setting this up properly does require some networking knowledge and how to properly implement security. The switches both work on hidden and broadcasted SSID Wifi networks. Half of my switches work on the hidden SSID and the other half are connected to the broadcasted SSID. They do support security password keys, but if you want an extra layer of protection, turn on your router/basestation's MAC address control to enable only recognized and authorized devices access to your wireless network.
I have assigned static IP address to these switches by way of their MAC addresses, to avoid IP conflict when power cycling happens to my router. This is the general rule for all of my stay-at-home devices.

Update 2017
My eleventh switch will be arriving tomorrow. The first switch I bought in 2013 is still working to this day. All switches are still working reliably.
Works perfectly with NEST thermostat, Amazon Echo and IFTTT.

Update Dec 2017
1. The WEMO App first lets you name each switch and then allows you to set up "Rules" for unattended on/off times to a switch or a group of switches. So that a switch or a group of switches will turn on/off at a scheduled time.
2. The Amazon Alexa App allows you to first create intelligent named "Groups" of switches, such as "Exterior Lights", "Interior Lights", "Living Room Lights", so you can use voice control to address them in a meaningful way. "Alexa, turn off Living Room Lights" or "Alexa, turn off All Lights."
3. IFTTT will integrate all the functionality of your smart devices with WEMO and ALEXA (NEST and others too). i.e. The GPS in a smart phone can be used to create an invisible fence that can turn WEMO switches on/off as you pass in/out of its perimeter. My living room lights and exterior lights come on when I'm about half a mile from home. NEST can also sense I'm coming home and start cooling/heating the house. The are thousands of "recipes" ready to use.

With these three Apps together, there are thousands of possibilities to automate your home if you are willing to experiment. These are just some of the ways I use mine.

Update March 2018
1. Recently purchased the Wemo Mini Smart Plug to make the uplights in the kitchen cabinets smart. Set up was easy but I first had to add the switch's MAC address to my basestation before connecting to one of my home's SSIDs.
2. That makes twelve switches and all are active and functioning as you can see.
3. The Wemo App is very laggy, but luckily with voice activation, I rarely launch the app except to take screenshots. I use Alexa's voice recognition instead. The Mac version of the app needs to support higher resolution displays like the Android one does.

该灯开关和其他插座式插头已可靠工作超过3年。偶尔会有像电源中断之类的小插曲，导致开关重新启。但我从来没有遇到这这种失败的例子。然而，你在网络连接的摆布下，如果你碰巧在网络崩溃时离开，你将无法与交换机通信。每日计划将继续工作不管。正确设置这一点确实需要一些网络知识以及如何正确地实现安全性的技能。交换机都工作在隐藏和广播的SSID WiFi网络上。我的交换机的一半工作在隐藏的SSID，另一半连接到广播的SSID。它们确实支持安全密码键，但是如果您需要额外的保护层，打开路由器基站的MAC地址控制，以便只允许已识别和授权的设备访问您的无线网络。我已经通过它们的MAC地址为这些交换机分配了静态IP地址，以避免在我的路由器发生功率循环时IP冲突。这是我在家里所有设备的一般规则。

2017年更新：

我的第十一个开关明天就要到了。我在2013买的第一个开关至今仍在工作。所有开关仍然可靠地工作。与NEST恒温器，亚马逊回声Echo 和IFTTT完美地工作。

2017年12月更新：

1. WEMO应用程序首先让您命名每个交换机，然后允许您为交换机或一组交换机设置无人值守的开关时间的“规则”。因此，开关或一组开关将在预定时间打开关闭。2. Amazon Alexa应用程序允许你首先创建智能的“开关组”，例如“外部灯”、“室内灯”、“客厅灯”，这样你就可以用语音控制，以有意义的方式来称呼它们。“Alexa，关掉客厅的灯“或者“Alexa，关掉所有的灯”。3. IFTTT将与WEMO和Alexa（或者Nest和其他产品）整合您的智能设备的所有功能。也就是说，智能手机中的GPS可以用来创建一个不可见的围栏，当你进出周边时，它可以打开或关闭WEMO开关。当我离家大约半英里的时候，我的客厅灯和室外灯就亮了。NEST 也可以感知到我回家，开始冷却或加热房子。它们有数以千计的使用方法。有了这三个应用程序，有成千上万的可能性，使你的家自动化，当然如果你愿意实验的话。这些只是我使用的一些方法。

2018年更新：

1、最近购买了WEMO迷你智能插头，使厨房橱柜中的吊灯智能化。设置是容易的，但我首先必须把开关的MAC地址添加到我的基站之前连接到我家的SSIDs。2、这使得十二个开关和所有的活动和功能，这个是你可以看到的。三、Wemo App是非常落后的，但幸运的是，可以语音激活，我很少启动应用程序，除了截屏。我用Alexa的语音识别代替。应用程序的MAC版本需要支持像Android系统那样的高分辨率显示器。

is to help anyone else who purchased this and is having trouble getting it to connect to your local WiFi network. I did get the unit working fine, but I removed two stars from my review because of the hassle of getting it to work. I spent over an hour with WeMo tech support, who offered no solutions, and made me jump through a bunch of hoops in the process. Cycling a reboot of my router did nothing. Changing my WiFi password did nothing. Disconnecting my phone from cellular service did nothing. The issue with these early units lies in the fact that they seem to get "confused" if you have other WeMo devices in your home. When trying to set up this WeMo mini, the WeMo app on my iPhone would find the device after I connected to its WiFi. The screen would show the device, ask me to name it, and click "Next". After clicking next, it would get stuck trying to get the device to find my home WiFi network. I have 4 other "older" WeMo devices (none of which ever had any issue connecting). I have a WeMo light switch, and 3 regular WeMo smart plugs. Two of the other WeMo smart plugs were easily accessible, so I tried completely unplugging them (not just turning them off). I did a factory reset on the WeMo mini I purchased, went through the app process of connecting it again, and voila! It immediately found my WiFi network and connected. And then it immediately downloaded a firmware update. So it seems like WeMo is aware of an issue, yet their tech support wasn't informed. And so far, I seem to be the only one publicly acknowledging the issue with these early release devices and buggy firmware.

So long story short, if you have other WeMo devices in your household, and have trouble getting this WeMo mini to connect, try unplugging as many of the other devices as you can (they will automatically reconnect online after you plug them back in), factory reset the mini, and go through the setup process again. It should hopefully work.
