I've encountered an issue with my device that prevents me from integrating it into the evie app or pheilix app. When I try to scan the QR code, it consistently shows as invalid. This is quite frustrating, and I would appreciate your assistance in resolving this matter. Additionally, I'm curious to know if there is a firmware update available for my model. Keeping the device updated is crucial for functionality, so any information you can provide regarding updates or potential solutions to the QR code issue would be extremely helpful. Thank you for your attention to this matter!
