Any one using Fanju 3390 WiFi which was sold by aliexpress
« on: January 28, 2025, 10:01:26 PM »
Long story short - I bought a device under the disguise it is Ambient weather WS-2902 with screenshots, pics, specs etc but unfortunately sold a ODM/OEM. Aliexpress refuse to accept responsibiity and stuck with this Fanju 3390 model

Now the problem is how can I connect this to WiFi. There is no manual I can find online and infact the search fwd me here and wondering any help. Thanks in advance

I don't know this station but surely is a clone

https://www.fanjuhome.com/products/fj3390-wifi-professional-weather-station/

It should be this one


It is like a Sainlogic FT-0835 but the console is different

I found a video about it in spanish

Finally I found this
https://www.lacrossetechnology.com/products/v22-wrthv2
Lacrosse V22-WRTHv2
Maybe sensors goup is different but the console look identical
Manual here

Oh my god, communication with aliexpress (seller & platform) for the last one week didn't yield any results. I don't even know what to say Zoomx for the help. Let me read the manual, watch the video. I think if I can get it to connect WiFi, job is half done. The V22-WRTHv2 looks similar. The challenge with the clone model I rcvd from Aliexpress doesn't have the side buttons + or - and I've tried many combinations to start the WiFi but in vain. Let me try this over the weekned one more time and hopefully I can get this good. Thanks a ton, once again. Appreciate a lot.

Just a thought.. but have you got the mains adapter connected?
One of my Ecowitt consoles will only connect to WiFi if the mains adapter is connected even though it has batteries in and you can use it with just batteries.

With regard to your missing + and - buttons, perhaps they are the up and down arrow buttons? press and hold them both down together for 2 or 3 seconds, maybe worth a try.

Good luck.

Sorry for the slow reply. Had to travel out for business.
Yes, its connected and batteries too. On the + or - buttons, there are up / down arrows and tried multiple times (may be easily 50 times). I think (strongly suspect) this is not a rep but possibly I've been scammed. The exact product is in alibaba - https://www.alibaba.com/product-detail/2023-FJ3390A-indoor-outdoor-wireless-Weather_1600969511182.html?  and based on the specs, it doesnt even have WiFi. While aliexpress shows this https://www.aliexpress.com/item/1005007819784415.html?spm=a2g0o.order_list.order_list_main.5.7a5718025n66Ug (what I bought) which is gross mis representation.

Trying to get refund from aliexpress and it's been a nightmare. Thanks for the help anyways.
