Revision as of 16:27, 2 April 2023

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.

Compatibility

The bulb has two product IDs:

  • LSH-B22RGB10W
  • CSH-B22RGB10W

Both of these are stamped on the bulb, these are not separate products: Laser Co seems to sell this bulb under its own brand and the Connect SmartHome brand it owns.

At least two hardware revisions of this bulb exist:

  • Older versions that use an ESP8266 chip
  • Newer versions that use a WB2L chip

This bulb is still sold so it's likely there are newer versions too.

These product IDs of the bulb have not changed between revisions, so there is no way to know if the version you have is the version I have.

As always, follow random instructions online at your own risk. You may brick your lightbulb.

That said: These bulbs need to be exploited to flash new firmware. If your bulb is incompatible with the exploit then nothing should happen. Otherwise it's likely the same hardware. Good luck.
