I don’t think so, personally, Cube on iHost is designed for that device.

Good afternoon!

For your information, I have two SNZB-02D.

From the i-HOST it is not possible to update to version 2.2.0. Both SNZB-02D were maintained with version 1.0.9.

But I used an ULTRA bridge as described by the forum user “Trice”: I paired them both with the ULTRA bridge and from this bridge I updated them to version 2.2.0.

Then, I paired them again on the i-HOST and here if the version 2.2.0 was maintained and I provisionally solved this problem.

I hope that it will be solved soon definitively for the next updates of the SNZB-02D.

Greetings.

Adolf Rupérez

@SuiKa Do we know when Sonoff will update the repository?
