Model: ES20M  
Hardware Version: V1
Firmware Version: 1.0.11 Build 240514 Rel.110351

I owned 2 Kasa ES20Ms. Every fews days, they hang and I need to push the reboot button for them to start working again.
Wondering if other folks are facing the same issue and what TP-Link is doing about it since this has been happening for several months now.

  @PJ78729 I have been experiencing the exact same problem and have not found a solution. I have 4 of these switches and they all have to be reset, it is not the router or connection because our wifi is stable.  Seems like faulty firmware.

Same for me as well. Very frustrating. Everything else on network is fine.

  @PJ78729 Same story on mine. I own two, one has to be reset and is probably 10 feet from a 2.4g only access point and the other disconnects frequently but a non-motion Kasa switch in the same box never seems to have issues.

Different issues may present similar symptoms, but this does not mean they have the same underlying cause. To receive efficient assistance, please provide as many details about the problem as possible.

 

Basically, we need to distinguish between different types of issues. For example, a device offline issue could be due to Wi-Fi disconnection (the device disconnecting from the router's Wi-Fi) or cloud disconnection (the device losing connection to the cloud server, making remote management impossible, while still being connected to Wi-Fi for local management). For these two types of issues, you can find relevant troubleshooting tips here. Cannot use the Tapo app to control my smart devices

 

If it’s a crash situation, this is a broader concept with varying symptoms, and more detailed descriptions are needed to identify the specific issue.

  @Wayne-TP thanks for responding. 
The physical buttons become unresponsive rulling out the simple connectivity issues. The switch seems to stay connected until this happens looking at the router clients. 
 

When in this state, the switch is not accessible through anything and even the physical buttons are not working. 
 

please let me know ifyou woupd like further info.

  @PJ78729 

 

I should mention that I have several other models of Kasa switches and do not have this problem.  Also, I've assigned static ip addresses to rule out network problems.

 

All switches are also connected to Home Assistant and third party integration is set to allow.  It is specifically the ES20M that locks up, as soon as I remove them from Home Assistant they work fine without issue, but it seems the issue cropped up after firmware updates.

For this case, we recommend reaching out to the technical support team for assistance directly, email to support.usa@tp-link.com. To receive efficient follow-up, make sure to include the following information in your email.

1. Model, hardware, and firmware version of your Kasa switch.

2. A video of the problem - when the switch 'hangs'.

3. How the issue is triggered, the frequency, and the way to restore it.

4. How long have you been using the switch and when did you notice the problem.

 

 

@John316-  Home Assistant isn't a supported third-party by Kasa. The product's performance cannot be guaranteed when used in unofficial methods.

  @Wayne-TP 

It's just sad that every other product you make works flawlessly, yet TP-Link cowardly and sheepishly hides behind the standard terms and conditions stating you don't work with Home Assistant. You are Platinum certified with Home Assistant and sell a ton of products because of that, but when it comes to trying to solve an issue, you slither away into some nebulous, lawyerly language.  Why can't you just do the right thing and fix the issue instead of being like most corporations? Be a Costco, Discount Tire, or Chick-fil-A, not a hopeless, amorphous mass just getting by with the bare minimum.

 

 

I know this was a waste of internet space, but damn, do better.
