What might cause Fibaro double switches to flash when trying to add Aeotec Multisensor 6?

Questions & Help
1

Hello something strange going on when I try to include an Aeotec Multisensor 6 (Devices > Add >
Aeotec > Multisensor 6 > Connect > press button once > press button again)

First, all the previously installed Fibaro Double Switch 2 devices toggle Q1 mostly lights flashing)

Second, the Aeotec Multisensor 6 installation fails or shows wrongly as a Fibaro Double Switch 2, which is also flashing / toggling Q1

Tried resetting the Aeotec Multisensor 6 and restarting Homey, and re-adding - got the same result.

Any ideas what might causing it / how to overcome it?

I guess you already installed the Aeotec App in Homey?
I did a factory reset of the Multisensor 6 and had it very close to the Homey when adding (less than 1 meter).
