Model: KL400L5  
Hardware Version: V1
Firmware Version: 1.0.8

Hello,

KL400L5 constantly disconnect from the network. I've noticed that after I turn them off and on for a couple of times they disconnect from the network. They usually connect in about 5-15 mins (sometimes not at all). Smells like a software bug to me. I can easily reproduce this issue. Just turn them off and on and eventually they will disconnect from the network. The error message on the app:

"Device Unreachable"

 

Your device may be powered off or out network range.

  @Antonio253,

Just so that i can ask the right questions:

 

Are you turning the device on and off at the app or at the device? Or unplugging the light? If you are unplugging the light over and over it could be causing the software in the controller to crash when it is starting up and potentially causing further issues.

  @Riley_S I am turning them on/off from the app only. They always disconnect from the network after some time.

  @Antonio253,

Are you able to tell if they are disconnecting from the network, restarting, or only disconnecting from TP-Link servers? 

If you are able to, can you see if the device is listed as online in the router logs?

 

Is there any identifiable sounds that could indicate that the unit crashed and is rebooting?

  @Riley_S The devices become unresponsive. When this happens, the app shows the error I posted and the device is grayed out in the app. My router also shows the device is offline and no ICMP response when I ping the device, hence, why I think the device is rebooting or something is making it crash. No, there are not identifiable sounds. Let me know if there is anyway that I can look at logs or some crash report.

  @Antonio253,

I will get in touch with our Engineers about the behavior and to see if there are any known compatibilities. For additional information, can you list your network setup, such as your Routers or Extenders in your network?

 

Also. would it be possible to have a video of the behavior to sent to our team, that way they can try and replicate the behavior.

  @Antonio253

Thanks a ton for the video,

One last question before I send this off to the engineers, what version of the application are you using? The team is constantly pushing out updates for the app, so I want to make sure that this behavior is still occurring on the newest version of the app.

  @Riley_S Yes, its the latest version of the application. I don't think its releated to the app it self. The device actually disconnects from the Network. Its seems like a device issue, not application (in my opinion).
 

It seems that this is a common problem with these LED strips (KL400L5), I have seen other forum discussions on this issue so I am not alone here.

  @Antonio253

If you go into the me section there will be a version number and a build number. The apps rollout in phases so you may be behind a version even if it is up to date in the app store. 

 

The reason it may be the app, is that i think that the issues that other users have reported have indicated an issue with the cloud connection. On user even had their device show as disconnected, but it reconnected when reinstalling the app. I just want to have all the bases covered, so we don't get a response from the engineers indicating that it has been fixed.
