Hello, I am new to Homey trying to use the Homey Pro 2019 version. I need to pair the hub with couple IKEA Parasoll sensors and with Danfoss Ally radiator valves. I downloaded the applications which are showing that they support the devices. Homey finds the device in the pairing mode and starts pairing but always fails with **“Unknown error occured”**. Does anyone know how to fix this?
