If Alexa is having trouble understanding the names of the devices:
- Do not use special characters (e.g., *(&%’#_) in the device names.
- Avoid typos or grammatical errors.
- Do not use conjunctions (e.g., and, or, etc.)
- Avoid using device names that are homophones of each other (e.g., Aaron’s Lights and Erin’s lights, etc.).
