Turn off LED help – Vanilla OPENWRT installed on Beryl MT13000

[eponymoussquid]

I have a spare Beryl v1, so I thought I’d have a play and installed vanilla OPENWRT, version:

“OpenWrt 23.05.3 r23809-234f1a2efa / LuCI openwrt-23.05 branch git-24.264.56413-c7a3562”

Kernel Version: 5.15.150

As far as I can tell, everything is working very well. I have 3 x SSID, one without VPN, the other two routing through a Proton VPN wireguard tunnel using policy-based-routing. I also have a pihole blocking ads, network wide.

What I cannot figure out now, is how to turn off the LEDs on the router.

When I was using the stock Gl.Inet firmware, I must have turned down the brightness because now, it’s super bright and my wife is complaining.

I have gone to:

Luci / system / LED Configuration – and turned everything to ‘always off (kernel:none)

But the light is still super bright.

Any help would be much appreciated.

Install package: i2c-tools
Enter command in console: i2cset -f -y 0 0x30 0x04 0x00

Add this line to /etc/rc.local to make this permanent after each reboot.

i2cset

I have a follow up question. As the internal storage is very small, I have just expanded the internal storage using Extroot with a USB drive.

extroot_configuration

But now, using the command: i2cset -f -y 0 0x30 0x04 0x00
no longer appears to work.

the latest version of the i2c-tools is installed Package i2c-tools (4.3-3) installed in root is up to date.

Now I'm using Extroot to extend the storage over USB, do I need to do something different for the command to work?

Thanks in advance for any help.
