I believe there is an issue with the recent Athom firmware .bin compile or flash on these bulbs. I received 4 bulbs. 1 I'm pretty certain is DoA. Of the working 3 bulbs, none will connect as a client to a Wi-Fi network. I even tried a few different routers / access points with no success. I am afraid to try to upgrade the WLED software because Athom writes a but of custom code in to be able to factory default the bulbs with an on-off-on-off-on-off-on procedure. This currently isn't something that is build into stock WLED releases. There is also other strange behavior on these bulbs as in other settings not saving other settings, presets, etc. In addition to the bulbs, I ordered some strip controllers and those are operating as expected, but they do have different builds on them. I am hoping that Athom can help. I did reach out via the "Contact Us" option and you said that you would send replacement bulbs, however, I do not want replacement bulbs if they will have the same issue as the bulbs I have now. Here is what I am finding: LB01-15W-WLED-1 - WLED 0.13.1 (build 2203150) - problem firmware / device
WLED ESP32 Music Addressable LED Strip Controller - WLED 0.13.2 (build 22102011) - WLED SR version 0.13.2 - seems okay
LS4P-WLED - WLED 0.13.0-b6 (build 2112080) - WLED 0.13.0-b6 (build 2112080) - seems okay
Any and all assistance is appreciated.
I would never have thought that out of the 4 bulbs I ordered, all 4 would be defective, but that is indeed what happened. Athom made it right and shipped me 4 replacement bulbs and all have tested good and I am satisfied.
I would strongly advise that they change production units from the TYWE3S module to an ESP-12F to improve Wi-Fi signal and mitigate some quality control issues. I would easily pay the minimal cost difference on these bulbs for this change.
Thank you Athom for making it right. Now to order some additional Athom open source devices...
I have spent *HOURS* trying to figure out what exactly is wrong with these bulbs. I've come down to either the power supplies are faulty and creating and low voltage situation causing erratic operation of the TYWE3S, or the TYWE3S is somehow faulty itself. I don't have the tools or skill set to know for sure. The odd part is that serial flashing works every time. I tried other builds of WLED and even Tasmota. All flashed to the ESP8266 successfully, but every time the erratic overall operation and Wi-Fi problems persisted.
So, I give up. There has been no other responses from Athom and it looks like every version of their 15W RGB bulb is now out of stock. Perhaps they realized there was a bad batch and pulled them. That is the only thing I can think of otherwise I assume others would be posting similar experiences.
