Troubleshooting: Smart Bulb Wi-Fi Connection Issues on 2.4GHz Band, Tested with Hotspot

Question

Hello. I recently purchased smart bulbs. I can not connect them to the phone, I did everything according to the attached instructions without effects. In the end, I tested them by connecting through the hot spot created on the second phone where they connected without any problem. And here the...

A model would be useful, a few other information would not hurt either. Greetings

Bulb model: Kobi Smart LED GU10 5W RGB

What else information? All I know is that this is not a light bulb or telephone problem. I tested on another phone with the same result and only creating a hot spot and connecting to it gave the effect and it worked without any problems.

Stitch12 · Answer

If the bulbs connect to the hot spot on the phone (which I assume you had at hand), it means that they work and I would look for the problem elsewhere.
I bet on Wifi. Perhaps one of the devices (light bulb or phone) was not connected to the same wifi network all the time when adding the device to the app

Neaxx · Answer

So I know as much as before. I just don't know why there is a problem with the wifi. The bulbs need to be paired so they do not connect immediately to the first better wifi, only in the application you need to select the network and then they start to connect, I made sure several times that the wifi was selected properly (2.4 band).

Stitch12 · Answer

The simplest mistake that comes to my mind is maybe you entered the Wifi password incorrectly on the app?

Neaxx · Answer

Well, I have entered the password so many times that I already enter it from memory, but it is correct because I always check it. I managed to connect one bulb, but when unscrewed and screwed in it was described as off the mains. As if she did not see wifi suddenly, although I have a router in my room.

There is one more application that looks identical to Tuya Smart. Why not try with her? It's called Smart Life.

Neaxx · Answer

Unfortunately, I have already tried that, even two others. They work on the same principle. : / Added after 10 [minutes]:

Stitch12 · Answer

Are you trying to add bulbs manually or by car? After looking at the photos, I played with my dimmers. I noticed that in automatic mode, the app does not detect devices. Maybe that's the problem

Check how your WiFi security is set - this may be the problem. Try to set WEP and see if it will connect successfully.

Neaxx · Answer

Set to WPA / WPA2, but unfortunately I will not check because I returned the bulbs.

gustdelf · Answer

Unfortunately, I got the same thing. After the purchase, I connected my polux bulb to the home router without any problems, but at some point, it ceased to be seen by Tuya. I tried both connection methods, and the bulb does not want to reconnect. I set up a hotspot on my phone and connected from there with no problem. There must be something on the router-bulb line wrong, just what? I will not change the key to WEP because it is not secure encryption without it. Is it possible to somehow remove this device from the router's memory? I suspect that there may be a problem here. I do not know about my router, but the Ubiquiti that is on the way, I know that it remembers the device. Maybe it does not want to assign a new IP to the bulb.

adwlodar · Answer

When the IP address lease time in the DHCP service expires, the router will forget it. You can also release it manually. What does ubiquiti mean? Access Point to WiFi? If so, it probably doesn't have DHCP service enabled, because that's what the router should do. Ubi's remembering has nothing to do with it. Added after 2 [minutes]: I don't mean to be malicious, but adding this type of shit to your home network is a bad idea - the problem of switching to WEP is just one of many. Turn on customer isolation in Ubi for sure.

Set an additional wifi band for guests in the router and connect the phone and bulb to them - it will work, if it works, connect the phone again to the normal wifi band and the bulb will stay in the guest band. You will be able to control the bulb without any problems

Marcin_Www · Answer

I read at the top and nothing helped, I was about to return them but ...

-App location must have access to full location (not just while running)
-The device (Android for me) must have unchecked permission to locate devices nearby in the settings of the pairing application

Then the app easily found and I could add a bulb-type device
(even in 5 GHz network)

xdtgs89 · Answer

So much setting, playing and it was enough to give these two permissions to the application (for me on android 13) mentioned in the above post and everything works without a problem ...
Thanks master you are great!

MironTV · Answer

You don't read the instructions attached to the lighting.
I had the same problem today.
The problem was not with the wifi or even with the device (phone), pull the plug and switch the plug on 3 times, after the 3rd try the lights should flash, then you can connect the device to the lsc without any problem. Greetings, goodbye.

Does anyone know how the bulb gets the wi-fi password and why they need my location?
