I’ve been on a journey to integrate several smart devices into my home automation setup, and I’m thrilled to share my experience! 
Recently, I decided to add three Sonoff switches controlled by Tasmota to my Home Assistant system. While setting them up, I encountered a common issue—only the last switch appeared in my configuration after a restart. After some research, I realized I was duplicating the switch platform in my config.yaml file. Once I corrected that by nesting all switches under a single switch platform, everything worked seamlessly! 
For anyone looking to achieve dynamic lighting based on time of day, I’ve implemented a solution using AppDaemon. It automatically adjusts brightness and color temperature throughout the evening and night. For example, it starts bright at 100% in the early evening, dims to 50% mid-evening, and goes even lower at night. This has been a game-changer for late-night trips to the bathroom without blinding me! 
Here’s a quick tip for anyone setting up similar automations: consider using a single AppDaemon script with configurable parameters for each light. This keeps your setup clean and easy to maintain. 
Would love to hear how others are automating their homes and any tips you’ve picked up along the way! Let’s keep the smart home innovations flowing!
