Newbie idiot to HA and ZHA, currently battling LEDVANCE Bulbs

I’m not sure why it is not working for you. For me my bulbs were upstairs, and as mentioned in one of those other threads that initial pairing connection is happening directly to the bulb from the device you are running tuya-cli on before it sends your SSID and password to the bulb so what I ended up doing was taking a laptop into the room with the bulbs and
running tuya-cli directly under the bulbs… I could never get all 3 to go at once so that’s why I ended up doing one at a time.

Do you have any info on the bulbs? Like a specific model/revision number on them? It isn’t out of the realm of possibility that some are coming with different chips than the original run that most people had. Also had you completely removed them from the sylvania smart life app?

Yeah I completely removed them from the app and my Model Number is LDVWIFIA100E27RGBW. I hope that helps and if its not the model number I would appreciate it if you could tell me where to find the model number.

I am also sitting right under the Bulbs with my computer.

I am having similar issue, I am running HA with a sonoff usb zigbee dongle, just bought a ledvance smart+ lighting zigbee, reseted it (it is blinking), but HA can’t find it. Do you have a solution for this?

Update Zigbee Coordinator firmware and use a long USB extension cable + follow general advice. See:


  • First batch came pre-flashing with older firmware from 20210120 which works out-of-the-box with ZHA and Zigbee2MQTT, however, it is highly recommended to at least upgrade to firmware Z-Stack 3.x.0 build 20211217 or later
    • Other than many bug-fixes the newer firmware offer +9dBm transmission power instead (instead of +5dBm transmission power) as well as the possibility to configure up to +20dBm transmission power via software settings in ZHA integration and Zigbee2MQTT respectively.
  • To avoid EMF interference strongly recommended buy and use → Long USB extension cable
    • Another reason for using a USB extension cable is that the USB-plug design of ITead’s Sonoff Zigbee 3.0 USB Dongle Plus hardware adapter is a little short which makes it harder and sometimes impossible to plug it into some USB ports if the computer enclosure/chassis/casing is to thick around the USB-port as that will physically prevent the USB dongle from actually making a proper connection inside the USB port even if it looks like it is plugged in all the way that is possible.
    • Also follow general tips in and as all Zigbee Coordinator adapters is very sensitive to EMI/RFI interference (e.g. a noisy radio frequency environment will jam the signal and prevent it from receiving all Zigbee messages to it without errors). Connecting the dongle via a long “shielded” USB extension cable in a USB 2.0 port or USB 2.0 hub (and not a USB 3.0 port) to get it away from EMF sources will usually help a lot if experiencing connection or pairing symptoms/issues.
  • Win/Mac need Silabs drivers → CP210x USB to UART Bridge VCP Drivers - Silicon Labs
  • ITead official FW flashing guide → SONOFF Zigbee 3.0 USB dongle plus firmware flashing
  • Unofficial FW flashing without open case →
  • Dongle hardware can also be used as Zigbee router (a.k.a. repeater) → flash router firmware

were you able to solve this Issue? I have the same Pairing Problems with Zigbee Dongle and Ledvance Smart+ Zigbee Bulbs

Hi, were you able to solve this? I recently bought some SMART+ INDOOR SWITCH MINIs. When trying to pair them with the Sonoff stick they immediately abort the pairing, nothing can be seen in HA, like zha events or sth. I realised that they don’t support Zigbee 3.0 and only Zigbee Light Link but they still should work somehow, right?
Interestingly when I hold them to an Ikea Repeater they don’t fail to pair, but still I can’t see anything in HA, no device discovered or any event sent.
