Model: HS100
Hardware Version:
Firmware Version:

We have a number of smart plugs and bulbs in the house. We use the Kasa app. Everything has worked faultlessly for a couple of years. Suddenly, all control has stopped working, for all devices, either locally or remotely. The devices are reported by Kasa as offline or unavailable. I have logged out, and back into, the app. I have turned off, and back on, the plugs. They appear to connect to wifi - green light - and can be turned on off via the switch on  the plug. But the app has ALL of them greyed out. I have tried to contact TP Link but no one ever answers. Any advice please???

@MikeP Thank you for the suggestion.  After much investigation, all devices came back online after I forced the router to rescan Wifi channels.  It was odd, because no other devices in the house were affected, only the TP Link plugs. But a rescan of channels fixed it, immediately.

You don't mention if you tried this, but if they're not flashing the first step is to force your phone onto your 2.4GHz SSID to see if it can find the switches. If it does, make sure remote access is enabled - then your phone will probably find the switches when you go back to your 5GHz SSID. If not, try rebooting your router. The problem must be network/app connectivity as it's unlikely all of your devices would fail at the same time.

@smithhn 

 

Hello, how many smart plugs and bulbs do you have? And what are their model number? 

 

Try to reboot the smart home devices; and you can delete the App and reinstall it. 

 

You can reboot the main router to give it a go as well.

 

Still the same, you can take one or two of them to reset and reconfigure. 

 

May it help.

@smithhn I have the same issue with my devices. How did you force the router to scan the channels again? 
 

thanks!

@smithhn what do you mean by "rescan the wifi channels"? I have this same issue and I've tried resetting the router but the issue remains. All ~20 devices working fine until this morning and now none can be reached.
