TP-Link Tapo P100

Hardware
5

Bad news I am afraid, it does not seem to work out of the box. I tried with discovery: true and with an explicit switch and IP address. No, luck.

I dug into it a bit, it seems that the HA tp-link component(1) uses pyHS100(2) as a dependency. pyHS100 seems to have been based of the great work done by a security researcher(3) and a set of libraries(4). The security research noted that ports 80/tcp, 9999/tcp and 1040/udp were open, this does not seem to be the case with the tapo device. Port 80/tcp looks to be open but it has a different API.

At first glance it appears to use requests to an /app endpoint with a token. The request and response looks like JSON enveloping around encrypted payloads.

{
    "method": "securePassthrough",
    "params": {
        "request": "..."
    }
}

{
    "error_code": 0,
    "result": {
        "response":  "..."
    }
}

I only got it in the post an hour ago so I will dig into it more later.
