I have created several advanced flows with Homey Pro 2026 that end with a speak message via Alexa. They have all tested well and have worked as intended …. for a few days. However, about every 2 to 3 days they fail. The reason consistently appears to be that the App (Alexa by Janie Speake) has lost contact with Amazon Alexa. ‘Repair’ requests Amazon log-in and password with the appropriate server which immediately corrects the problem for another few days. I am delighted with the results when they work but the inconsistency means I cannot rely on them for warnings etc. Is there a known problem with Alexa and how can I overcome this?
