"only to some TP-Link official partners like Alexa and Google"

Is there a cost associated with access to the API ? Or is there an avenue to sign an NDA to gain access to the API?

Have you tried some API docs on Github to controlling Tapo smart plug, I found one that works for Tapo P110.

  @Little_C I also got annoyed after my last kasa plugs order supplied me tapo plugs with the same issue.

A bit of poring thru the tapo and kasa github code, some tinkering on node-red, and I produced a POC node-red flow

for accessing both tapo and kasa devices (in my testing; I use the same logins for both apps)

Note the forum won't let me paste the flow contents here - it complains about illegal URLs

I've recently built a Rust API Client that works with TP-Link Tapo smart devices. Tested with light bulbs (L530, L510) and plugs (P110, P100). You can find it at https://github.com/mihai-dinculescu/tapo.

Yes, Tapo uses the same API server as Kasa. Google kasa API Joshua for information.
