That's why I've been touting the Smartenit product. For as little as $75 (Harmony P2.with 2412U PLM) you get a we'll supported product that exceeds the capabilities of the WM100 and the PiX10Hub combination. It's been running perfectly since installation in March '19. Having an actual Alexa Skill makes it a no brainier and the Harmony firmware automatically updates as needed. The additional support for Insteon and ZigBee adds to the flexibility and allows the 3 protocols to interface seamlessly. It runs schedules with all the expected dawn/dusk variables based on location, does DST and internet time and does email & text notification. Everything is set up through an app or web portal. It's a very well thought out product.
