General Issues

1. If the logs show "COMMS_MANAGER: Unable to fetch device info: -1" . You may need to enable third party compatibility using: https://www.tp-link.com/au/support/faq/4416/ . If Device still ceases to work, replace the KLAP Device driver with the V2 Outlet or light, and set the correct Mac address if using agent (or IP, if not using Agent)
2. If you are using Control4 4.0.0 or later , you must be using version 20250721 minimum for full support in all drivers.  In particular, Versions older than  20241209 will not operate in X4 at all due to changes in Control4, and must be upgraded for any functionality. 
   
3. Ensure the driver is showing licenced or is operating in trial mode. If you upgraded from a purchased version older than 20240805, you may need to also migrate the licence to Chowmain marketplace
   
4. V1 drivers are no longer supported. Ensure that all V1 drivers have been removed from project, and they are replaced with supported drivers. You may need to reboot controller after doing so
   
5. Run Display Diagnostics, and check the output in Lua Terminal
   
6. Ensure that the devices are running the latest firmware. 
   
7. In TPLink agent, ensure that the TPLink Account credentials have been added  
   
8. 
   

Tapo P100 Outlet (And Other Tapo Devices) Unable To Authenticate

1. Ensure that the Tapo P100 or Tapo device is running the latest firmware. Old firmware uses the Klap V1 protocol which is not supported
2. In some circumstances, the device is unable to connect despite having the correct authentication details entered into Control4. This issue can be resolved by factory resetting the device and re-adding to the TAPO account using the Tapo mobile app. Generally, the driver itself requires no reconfiguration, and will simply work

V2 Device Has Ceased Operation

1. Check the IP address in the Control4 driver is correct
   
2. Ensure that the device can be controlled from the TPLink Mobile App
   
3. Some firmware updates update the driver protocol to  KLAPv2 (either via Automatic Update, or manually). Check Diagnostics in TPLink Agent which will be able to identify if the device is using the V2 driver, instead of the correct Klap device driver. If so, you will need to replace the V2 driver and replace with our KLAP drivers. EP25 and KP125 are two products which are known to have received updates which require the V2 driver to be replaced with KLAP
   
4. UDP / broadcasting is not working correctly on the network. The most common cause of this is that the network has been reconfigured incorrectly, or IGMP has been enabled. Test with IGMP Snooping disabled, and if it works, reconfigure network for correct operation
   
5. Ensure that all devices are in the same network segment. Some WiFi AP's (particularly Mesh) may not route UDP broadcast traffic correctly
   
6. Check WiFi signal for device

KLAP Device Has Ceased Operation

1. This may occur due to a change of the TPLink authentication details in the Mobile App. Please check the username and password in the TPLink Agent
   
2. Ensure that the device can be controlled from the TPLink Mobile App
   
3. If Authentication is failing and the device has been newly added, factory reset the device using the TPLink App.  In some circumstances (particularly the Tapo P100), authentication may fail without the factory reset after the firmware update has been performed.  
4. If this device has just been added using Auto Setup, we have found in some cases that the device may have been detected incorrectly as a KLAP instead of V2 device. Delete the KLAP device and test using V2 Light / Outlet instead
