Hue bulb adding to ZHA with SkyConnect

Hi,
Recently I received the SkyConnect.
Now I have troubles with connecting my last 2 bulbs to ZHA, model LWB010, without BLE i think.

I’ve deleted the bulbs from the Hue app, and tried the TouchLink though Bridge API. The bulb is flashing after the procedure. But I can’t find them within search of ZHA thereafter.

Got someone a solution for this? Was thinking about firmware SkyConnect Switch or firmware Bulbs.
But I don’t know how to update the first one. The second one seems not possible due using an old v1 bridge.

EDIT: Checked firmware bulbs, is a last one v1.50.2_r30933.

Kind regards.
