How does it work?

I have a Candy RO4274DWMS7/1-S washing machine.
As I understand it, it isn’t possible to read the remaining wash time locally over Wi-Fi without using the hOn app and without an active Internet connection, is it?

In pairing mode, the machine broadcasts a Wi-Fi network with the SSID WIFIWASHMACHINE-14d6. After connecting to this network and issuing the command:

curl -k https://192.168.0.1/http-read.json?encrypted=1

I receive the message:

This URI does not exist

Once the machine connects to the router, HTTP/HTTPS on its IP address no longer works.

How, then, does the official hOn app (and likewise Andre0512’s pyhOn) communicate with the machine? Is it like this:

1. The washer connects to the home router.
2. Through the router, the washer acts as an HTTPS TCP client(?) and connects to the Haier cloud.
3. The hOn app sends a request over the Internet to the Haier cloud to fetch the current parameters (including remaining wash time).
4. The Haier cloud sends a query (via the connection established in step 2) to the washer and receives its response.
5. The Haier cloud relays that response back to the hOn app.

Is that how it works? If so, it’s crazy that you need an Internet connection just to poll the washer for its status.
