Changed my Internet provider so have new wifi name and password. Have spend my whole Sunday afternoon trying to connect my 3 smoke detectors to the new wifi. I have now managed to disconnect one of my devices. I have uploaded to the latest app and followed instructions. Why does this have to be so difficult. I'm annoyed as I have spend over €300 for this product thinking it was quality and easily setup. It was easy to setup but impossible to change the bloody wifi. Very disappointed with this.
