Troubles with Lohas devices

[unlucio]

Hello,
I have 4 spotlights and a bulb from Lohas:

I can control them using the Tuya app, and they appear in my Tuya developer portal. However, when I try to scan them, I mostly receive ECONNRESET errors across all protocols:

➜  ~ tuya-cli get --ip 10.6.9.69 --id <my device id> --key <my devce password> --protocol-version 3.1

      ^

If I nmap them, they all have the 668 TCP port open:

➜  ~ nmap 10.6.9.69
Starting Nmap 7.95 ( https://nmap.org ) at 2025-01-12 14:47 CET
Nmap scan report for ESP_B2D874.local (10.6.9.69)
Host is up (0.025s latency).
Not shown: 999 closed tcp ports (conn-refused)
PORT     STATE SERVICE
6668/tcp open  irc

Nmap done: 1 IP address (1 host up) scanned in 2.61 seconds

I briefly managed to communicate with 1 of them using protocol 3.1 and get a list of datapoints, but it stopped responding afterward.
They all work fine in the tuya app.
I find the whole Tuya stack very confusing, and that doesn't help.

Can someone help me find some clarity? and perhaps to fix my white problem?
