This post is going to cover normalizing all media_player volume levels with Home Assistant and Node-RED. If you haven’t already, I’d recommend reading my previous blog post on sending Text-to-Speech notifications which dives a bit deeper on the optional accessibility Subflow this Flow consumes.

Have you ever wanted to send Text-to-Speech (TTS) notifications with Home Assistant and Node-RED? In the sections below I’m going to be using Amazon Alexa Media Player Integration to send TTS notifications. Please note you can easily switch out the TTS integration to the one of your choosing and still use this Subflow (with a few tweaks).

I define accessibility as a critical necessity to be inclusive to everyone. No matter how big or small the task, anyone should be able complete the task at hand regardless of the disability (e.g., vision, hearing, mobility, device access, language, etc).
