CSH-B22RGB10W
In 2021 I bought a Connect 10W Smart RGB Bulb for my room so I could have a dimmable light without installing a dimmer in my house. It cost around $10 and I promised myself I wouldn't hack it.
In 2023 I was annoyed at having a dimmed lightbulb. I logged in to the app and brightened my room, but the anxiety of using cloud services to dim a bulb set in. I promptly flashed new firmware and after a few hours of reverse engineering and troubleshooting, managed to have light in my room again.
This page documents roughly how to do this and my hardware findings.
