Efficient Management of Identical ESPHome Devices

Hey everyone! I’m currently working on a project where I need to manage 30 identical light switches using ESPHome. It’s been quite the journey, and I wanted to share my experiences and ask for advice from the community.

Initially, I was manually adding each device to ESPHome Builder, which was time-consuming and repetitive. I started exploring ways to streamline the process and came across the name_add_mac_suffix: true option. While this worked for assigning unique hostnames, it didn’t apply to other components, which was a bit frustrating.

I’m also curious about handling API keys in this setup. My ideal scenario is to maintain a single “starter” firmware that I can flash in bulk and update via OTA. I’ve heard that this is how “Built for ESPHome” devices are managed, but I’m not entirely sure how to implement it effectively.

Has anyone else tackled a similar project? I’d love to hear about your strategies, whether you’ve used bulk flashing techniques, or if there’s a more efficient way to handle firmware updates and API key management. Any insights or tips would be greatly appreciated!

Looking forward to your thoughts and experiences!
