@JimT1000 I had the same problem and was frustrated when my plugs and lights became intermittently "Local Only".  It wasn't until I rebooted my router that I realized it was the comcast gateway.  I replaced the gateway and the problem is fixed.  No firmware upgrades, no delete and reinstall of the plugs needed.  Start by simply rebooting your gateway.  Hope this helps.

@thelopi  rebooted many times....no joy

I want to turn them off remotely and the setting is gone. It's a tv device I have three networks, all are part of a bigger network but tplink doesn't see them as one, and I don't want to have to figure out which network I'm connected to/the tplink is connected to early in the morning/late at night when I switch the device connected to the TV off because it's going to take me a while due to restarting the app and whatnot/piss me off.

Going back to the old app wasn't working earlier today. I'll give it another chance tonight.

Seriously hope its a bug that gets fixed soon.

Damm even I am having a similar kind of issue, I have searched all over the internet and even have posted on number of threads on different forum, no solution seems to work. I am really frustrated, can anyone of you here help me resolve this issue, I am very much tired now.

Hello everyone, my issue has been solved as i upgraded my router. My wifi signal is stronger than before and the HS200 connects and works well already for few months since changing rounter. I think most of problem/issues are from network. If you have the same problems, just try first with the wifi network which giving stronger signal and more stable to HS200. 

I have been fighting the Local Only problem for months, and finally solved it (at least, solved it for me). Bottom-Line-Up-Front: Set ALL of your smart devices to a new Reserved IP address in your router. Read on...

Mine boiled down to a bad DHCP lease from my router.  My router provided an IP and Subnet to the smart switch, so I was able to get to it Local Only, with the Kasa app. But it was not providing a proper DNS and Gateway, so the switch wasn't getting to the internet.  I solved this by adding the switch's MAC address to my reserved IP table of my DHCP server (on the router).  When I did this, I gave it a different IP than what it was currently using, outside of the DHCP pool, saved it, and restarted the switch.  And it has worked perfectly ever since!  By giving it a *different* IP from what it was using, it forced the lease to update with the full credentials, and as it is now reserved, it doesn't lose it anymore. *Works*Perfectly*

My Best Practice suggestion:

I have now set up an additional WIFI access point, dedicated entirely to my home automation devices. It is 2.4ghz for wall penetration, SSID turned off, and set with an iron-clad (20char) wifi password. It is set up as an access point, so it simply relays the configuration from my main router.  *All* of my Smart devices are set with reserved IP addresses (15 devices). And I have no more problems.

Note: One of the reasons why my IP leases weren't working right...  There was something wrong with my DHCP lease expiration timeout, and *none* of my leases were expiring on my router.  Once the pool of 99 IPs had been exhaused, my switches were dropping off, and I was getting all sorts of Local Only issues. This would also explain why some people on here fixed their problem by upgrading their router...  A new router would re-issue an entirely new IP lease, forcing the switch to update it's DNS/Gateway. 

Hope this helps someone!

@PeterG Thank you very much for this!

I posted here a while ago saying that I suspected the problem we were experincing was due to network configuration.

As I'm not very network-savvy yet, I wasn't able to diagnose the problem but was shure it wasn't the smart plugs as they worked on other networks from different houses.

Mine didn't work in the office where I work. I know they have a different configuration and the network is larger than the typical home, with many routers.

I encourage everyone having this "Local Only" issue to try @PeterG 's fix.

I don't have the time or expertise to go through all this network troubleshooting and constant rebooting/resetting.  Sadly, TP link smart plugs replaced with Amazon smartplugs was my solution.  As much as I wanted to support this company, there's no point in having smart plugs if I can't  control them remotely.  At least I know Amazon will keep up with updates that allow their devices to remain functional.

@Pipedog I also bought Amazon Smart Plugs to try out and all 3 of them have a critical issue, according to my tests:

THEY TURN OFF WHEN THEY ARE DISCONNECTED FROM THE INTERNET AFTER A COUPLE MINUTES!!!

Can you imagine that?! I have tried all 3 of them in different networks and buildings. I also tried them with different devices, as I thought I might have been overloading them. But no, even with the smallest of loads (like a lamp with a single LED bulb or a Wyze Cam), the "Smart" Plug turns off if it becomes offline, and then it doesn't even turn on automatically.

Needless to say, this is unacceptable for a Smart Plug. For example, if an outdoor night light is connected to your Amazon Smart Plug, and the internet goes down for a couple minutes in the middle of the night, the light will turn off and then remain off for the rest of the night. Same for a security camera, computer, fan; etc.

Other downsides, in my opinion, are:

- The Amazon Smart Plugs can't be controlled locally without an internet connection.

- The on/off button is small and hard to feel and press, especially if the smart plug is located somewhere hard to reach.

I really like the physical design of the TP-Link Smart Plugs as well as the Kasa app. I wish they could just listen to us and fix these network issues so we can keep using this great product. If I were you, I would find some YouTube tutorials on how to change the settings in your network or ask a techy friend to help you so you don't lose your investment.

In the meantime, another alternative is to buy Smart Life compatible Smart Plugs from brands like GoSund , Teckin; etc. They have great reviews on Amazon and all the light switches I have and control from the Smart Life app work instantaneously in local mode. They are usually cheaper as well.
