Smart bulb toggling once a second and Wi-Fi connection failure

edward

Hello,

I recently purchased a set of seven smart bulbs, which I successfully installed and integrated with Home Assistant. However, I’m encountering a persistent issue with one of the bulbs in my kitchen.

Initially, this bulb was connected and functional. It later disconnected from the Wi-Fi and became unresponsive. To address this, I attempted a reset by power cycling it six times, which allowed access to the Tasmota device’s web interface via its default network at 192.168.4.1. I reached the Wi-Fi network selection screen and entered my network details, but unfortunately, the bulb failed to reconnect to my Wi-Fi. It now continuously toggles on and off every second.

Despite multiple attempts to reset the device and clear its configuration through the web UI, the problem persists. I can consistently access the Wi-Fi selection screen, yet the bulb remains unable to establish a stable Wi-Fi connection and continues to flash.

I tried selecting ‘reset configuration’ from the Web UI, this did not fix the problem.

Could you please provide guidance on further troubleshooting steps? Are there any specific settings or procedures I should try to resolve this connectivity and flashing issue?

Thank you for your assistance.

Hi Edward,

The only other fix I’d suggest is a firmware update during the period it’s successfully connected…
Another suggestion would be to locate it closer to your router as a step to rule out it being just a signal issue.

Aside from that, the ESP chip may be being weird, so feel free to drop us an email, and we’ll sort you out 🙂

I hope this helps!

Thanks for the advice. I followed your suggestions and now the smart bulb is working again.

I moved it closer to the Wi-Fi, it managed to connect to the Wi-Fi and it stopped toggling on and off. The web UI showed Sonoff Basic, so I imported the template like it says in the documentation.

The smart bulb is working correctly in my study, but not in the kitchen, which must be a problem with the Wi-Fi signal not reaching. I’m going to order another access point to improve the Wi-Fi in the kitchen.
