Curtain Switch with OTA flashable FW

[ChrizZz90]

Hopefully, you guys can help me...I bought a Loratap SC500W and thought I could flash it, but the OTA option didn't work and I couldn't manage to serial flash it.

Now, I hope some of you could successfully OTA flash a curtain switch in the last weeks. Please tell me which device, where you bought it, and in the case of a marketplace which reseller.

I know, this doesn't guarantee that I receive a device with the old firmware, but the chance is there.

Thanks for your help...
