I am sorry Sofia but your response is unhelpful and just makes your customers even more disappointed in their purchases. 
 

It is not hard to combine the two product on a single app. As seen in an earlier post a third party was able to do it on IOS. If a third party can do it then it stands to reason that the company that developed the platforms can do it even easier. Fact is it has nothing to do with how hard it is and simply TPLink has no interest in doing it. Two very different things.

This is a product sector that is all about convenience and having two incompatible lines is very inconvenient for your customers hence the backlash. TPLink can choose to ignore that but I suspect they will loose customers as a result. Simple fact is if anyone is looking to build up a smart home then they need the various products to simply work together or it is not very SMART.

To that end I have a few questions:

1) Is KASA planned to be replaced by TAPO? I am new to this and will be very disappointed if I continue my investment in KASA only to have your organisation drop it in favour of TAPO. 
 

2) do both platforms support API control and interaction? If so will the remote support of this continue even if you end of life One of them?

I am here to join the crowd.  I have way too many apps for my smart devices and having two of them for the same company is dumb.
