That is not correct. Because Kasa KE100 ist fully supported in current Tapo App 3.6.116 Release version (not Beta) via Google Play Store.

I can add KE100 to my H100 Hub (no need for KH100) in Tapo App without any problems.

If you have no option to add another KE100 or your previously added KE100 disappears in the Tapo app, contact TP technical Support Team. They are aware of this issue.

This behavior is account related. TP Link have to made some special adjusments to your account.

After this you should able to add and manage your KE100 valves again in the Tapo app.

This worked for me and many others with this issue.

Thats what I wrote before: Account and/or Country (Region) related issue, not an Tapo App issue.

  @Jebeyer Ok I understand and thank you!   And if I may ask, is it possible to know when it will be available in my country or can I do something to make it available in my country as soon as possible?

I'm not an TP Link employee nor working for TP Link.

I'm also only a simple costumer.

So I can't answer your question.

Please contact your local TP Link Support Team.

Thx.

  @Jebeyer Of course I understand, thank you.   And 1 more question, where can I contact the local tp-link customer service?
