Hey everyone, I’m thrilled to share my recent journey with ESPHome and how it’s transforming my home theater setup! As aavid DIYer, I’ve been diving into the world of custom integrations, and I’m currently working on something pretty exciting: controlling my Denon receiver via RS232 using ESPHome. While I’ve got the basics down—like switching inputs with UART commands—the real challenge has been figuring out how to use the brightness slider of a virtual light in ESPHome to adjust the volume.
Here’s where things get interesting. I know the light component in ESPHome doesn’t support UART directly, so I’m brainstorming ways to make this happen through automations. My current idea is to trigger a UART command when the light’s brightness changes, effectively mapping the slider to volume adjustments. It’s a bit of a hack, but I’m optimistic it could work!
I’ve shared some of my code snippets and would love to hear if anyone has tackled a similar project or has tips to make this smoother. For instance, how do others handle the conversion from brightness values to specific volume commands? Any advice on ensuring the UART communication stays reliable would be invaluable.
This project has been a fantastic learning opportunity, and I’m eager to see where it goes next. Whether it’s perfecting the volume control or exploring additional features, I’m all in for the ride! Let’s keep the conversation going—your insights could be the key to making this integration even better. Thanks for your support and wisdom!
