Virtual Switch for Washing Machine Notifications

Hey everyone, I’m trying to set up a virtual switch to notify me when my washing machine is done. I’ve installed a power sensing switch on my washing machine, and it sends a notification when the power drops to zero. Now, I want Alexa to tell me, ‘The wash is done,’ but I’m not quite sure how to set this up. I’ve tried a few virtual mechanisms, but none seem to work. I was wondering if anyone has experience with this or could suggest the best way to trigger a voice notification. I’m using a power sensor, and it works well, but I need help connecting it to Alexa. Any tips or advice would be greatly appreciated! I’m really looking forward to getting this working so I can be notified without constantly checking the machine. Thanks in advance for your help!
