This guide provides step-by-step instructions on how to get the button on the LAMY Al-Star EMR pen to work as an eraser on the Remarkable 2. The steps to do this are relatively easy and will be safe for most people and take under 10min total.

I don’t take responsibility if you break something and can’t provide support. That all said, I have done this and it worked for me, so sharing for others. I am not associated with the hack, Remarkable, or LAMY.

If you’re trying to make a decision about using the LAMY EMR pen with your Remarkable 2, I can absolutely say it’s worth it. It’s a better experience than the standard Remarkable 2 Marker, using the button as the eraser is life-changing, and overall I prefer the feel of the LAMY pen. The best LAMY Al-Star pen for the Remarkable 2 is this one on Amazon.

For the best writing feel, you need to swap the tips on the LAMY for those used in the Remarkable Marker. Remarkable’s Marker tips (also available separately) just have the right friction, but the LAMY tips do work “as is” if you want.

If you’re interested, I wrote up a review of all Remarkable 2 Marker alternatives here. If you don’t want to hack, there are after-market pens, like this Staedtler Noris Jumbo model, that have a built-in eraser and work like the Remarkable Marker Plus without a hack.

Before you begin…

I would encourage you to turn off automatic updates on your Remarkable 2. This is because software updates will disable the Remarkable 2 LAMY Eraser hack and you will need to reinstall it. It’s always a little frustrating when an update happens when you’re at work and don’t have time to reinstall the hack.

To disable Remarkable 2 automatic software updates.

Settings > General > Software > tap the Version number > Switch Automatic Updates to “Off”.

You can always manually check for updates as needed in the same menu setting should you want to update the Remarkable 2 software. Just always remember that updates erase the hack. But don’t worry, you can always reinstall the hack and continue with a working LAMY eraser button on your Remarkable 2.

Once all of this is done, you’re ready to begin!

Step 1. Get the IP Address and Root Password of your Remarkable 2

First, you need to get the IP address and root password for your Remarkable 2, you can find these details in:

Settings > Copyright & Licenses

At the bottom of the screen, under “GPLv3 Compliance” you will find your Remarkable 2 password in bold. Remember, passwords are CaSe SeNsItIvE. The password will also change if you ever reset your Remarkable 2. It’s safe to leave your Remarkable on at the GPL screen during the process so you can just read and copy the password.

The IP address of your Remarkable 2 will be the last thing you see on this screen. If you see two IP addresses listed, it’s because you have your Remarkable 2 connected to your computer via USB C, the second IP address will be one you use to connect via WiFi to install the LAMY Al-Star Button Remarkable 2 Eraser Hack,

Step 2. SSH into your Remarkable 2

You now need to SSH into your Remarkable 2. Your Remarkable 2 and computer will need to be on the same WiFi network. This means this is typically something you will need to do at home as the Remarkable 2 will not authenticate on networks that require a browser window to open e.g. offices, hotels, cafes, airports. See this Remarkable WiFi FAQ.

I recommend turning your Remarkable 2 off/on before going through all of the steps below. If your Remarkable 2 goes into sleep mode as you’re entering commands, you will lose the connection and need to pick up from where you left off. Which means SSHing in again, etc.

Tip: On both Windows and macOS you will be promoted to confirm you trust the authenticity of the host and the RSA fingerprint when you first SSH into your Remarkable, make sure you say yes.

Windows and macOS Users

On Windows 11, you can start a Terminal/Command Prompt in Admin mode, on macOS you can start Terminal. On both Windows and Mac you connect to the Remarkable 2 using:

ssh root@<IP Address>

where IP Address is the IP Address of your Remarkable 2.

You will be prompted for your password (remember it from Step 1. Then, if it’s your first ssh into your remarkable, to confirm and accept the ssh key (say yes!).

If you entered your password correctly, you will get the Remarkable Zero Sugar login confirmation as per below. This is from my Mac, but it looks pretty much the same on Windows.

Step 3 Install the LAMY Al-Star Remarkable 2 Button Eraser Hack

There are a few LAMY Al-Star EMR pen Remarkable button hacks available, I use this GitHub repository as it only installs the LAMY eraser hack and nothing else. It’s also very easy to uninstall should you change your mind.

  1. First, you need to create a directory for the LAMY Eraser hack.
cd
mkdir RemarkableLamyEraser
  1. Now you need to change to the directory and install the LAMY Eraser hack binary and the service.
cd ~/RemarkableLamyEraser
wget https://github.com/isaacwisdom/RemarkableLamyEraser/releases/latest/download/RemarkableLamyEraser wget
https://github.com/isaacwisdom/RemarkableLamyEraser/raw/main/RemarkableLamyEraser/LamyEraser.service
  1. Now you need to make the binary executable, start the LAMY eraser hack service, and configure it to restart on boot.
chmod +x RemarkableLamyEraser
cp LamyEraser.service /lib/systemd/system/
systemctl daemon-reload
systemctl enable LamyEraser.service
systemctl start LamyEraser.service
  1. You’re done!
Step 4 Using the LAMY Al-Star Button Hack on your Remarkable 2

The Remarkable 2 LAMY Al-Star button hack has two default behaviors, as follows:

  • Erase: press and hold the button to erase, release to use as a normal pen.
  • Undo: double-click the button to undo

You can customize the buttons, but I haven’t found any real need to do this. Customizing the buttons requires additional commands, starting and stopping the LamyEraser.service, etc. which is more trouble than it’s worth.

Removing the LAMY Al-Star Eraser Hack from your Remarkable 2

If you change your mind and want to uninstall everything, just SSH back into your Remarkable 2 and run each of these commands. This stops the service, erases it, and deletes all of the associated LAMY hack binaries.

systemctl stop LamyEraser.service
systemctl disable LamyEraser.service
rm -rf ~/RemarkableLamyEraser
rm /lib/systemd/system/LamyEraser.service
systemctl daemon-reload
systemctl reset-failed

General SSH Tip

Windows 11

If you need to delete all of the .ssh keys on your Windows PC, you can do this via Command Prompt/Terminal.

Windows put .ssh keys in the \users\<username>\.ssh folder. Just change to this directory and delete “known_hosts” but please note this will delete all ssh keys.

macOS

If you need to delete all the .ssh keys on your Mac, you can do this via Terminal using this command, it too will delete all current ssh keys, so be careful.

rm -rf ~/.ssh/*
