I can return for a refund in GR, the purchase is local and I can return the item within 14 days if not satisfied, no questions asked. But still, this is an item that does not perform as expected and it is only 5 days in my hands. I will opt for another led strip.
I am not saying the ledstrip is bad, but the wifi protocol chosen in the controller, is ancient in wireless terms if it is a simple 802.11.
The box of the led strip says 802.11b. Legacy wifi does not need to be present with 802.11b, unless of course the 802.11b exists only in printed paper.
Some other brand led strips work great when it comes to their connectivity but the controller fails and others have a problem with the strip and the leds itself. It is very difficult to find a good and reliable led strip, whether RGB or RGBIC. Other led strips I have used were TP-Link RGB, similar to this Sonoff. I bought 4, the controller in 3 of them died in under 6 months. I find this to be a pattern so I requested a refund for all of them and managed to get my money back.
Producers need to make reliable devices. It is better than making them cheap. The long term reward is much more profitable.
As for the reply, I really wish you good luck. My other support topic where I was asking for help, got unlisted by an admin and the topic now has a private link. This means you cannot find it unless you know the link to it. How am I supposed to get help here? I was told to raise a ticket. I raised a ticket on 21 January 2023. I got an answer 15 days later where I was asked things I explained in detail. When I replied explaining the same things I wrote in the first place, asking support to read before answering, I got nearly the same answer, plus more of a confusion from support which sounded as if they were writing to another customer. I asked for someone who can read and write English so we can communicate properly, I even made 8 videos since words were not understood, and I have received no answer since February 10. Two weeks now waiting for some kind of “support”. So when I wrote in this help and feedback forum, they unlisted my topic making it private. They left a message asking me to raise a ticket “especially for software-related issues”, when the problem is not software but hardware. Needless to say that I have already raised a ticket as I wrote. It is more than 1 month now they cannot even understand what I am writing, not to mention they are not replying to my ticket last 2 weeks, athough I have sent 2 reminders in this time. But hey, raise a ticket and we will remove the post in the meanwhile so you can get no help at all. 
So once more, good luck expecting an answer in the problem, even more good luck if you raise a ticket. 
Switches are great, this 1 bad out of a total 10 switches, really kills me though…
