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).
