How Can We Help?
Use a USB Keypad to Control Home Assistant
Not everybody wants to talk to Alexa just to turn a light on. A cheap USB numeric keypad can become a physical Home Assistant controller.
Pass it through
If Home Assistant is a Proxmox VM, add the USB keypad to the VM and reboot if necessary.
Find the input device
Under Settings → System → Hardware → All hardware, find the keypad input event such as /dev/input/event3.
Configure and learn key codes
Add the keyboard-remote configuration to configuration.yaml, restart, then listen for keyboard_remote_command_received events while pressing each key.
Create automations
Use event triggers for the key codes. Trigger IDs and a Choose block let one automation handle several buttons for lights, curtains, TV controls or scripts.
