Signal

Prepare the core’s computer

Signal uses signal-cli, which you install and link to a Signal number separately. It can be a dedicated number or a linked device for your account. APX does not install or register it for you. Run the daemon on the computer hosting the core, not merely the phone or laptop showing the panel.

For a number already configured in signal-cli, start its HTTP daemon, replacing the placeholder with that number:

signal-cli -a +NUMBER daemon --http 127.0.0.1:8080

Keep this HTTP endpoint private: access to it lends access to the linked Signal account. Do not expose it on the internet to solve a connection problem.

Connect and identify yourself

1. Open Settings › Channels › Add channel › Signal.
2. Enter the signal-cli address and the number, and select the agent that answers.
3. Write to the linked number from your own Signal account. Enter the code under This is my Signal to identify your account; approve other people as contacts instead.
4. Send a simple test message and check the answer both in Signal and in APX’s channel conversation.

Only one-to-one chats are read. Linking Signal does not enable group conversations. Review Strangers and Your messages as described in the channel overview.

Questions and troubleshooting

Signal can establish the sending account, but only after you link the correct account as yours. Questions and confirmations arrive as numbered options; answer with the number shown. Settings changes that require the APX app must still be approved there.

If the channel is unavailable, check that signal-cli is linked and its daemon is still running at the saved address. A remote core cannot reach a daemon on your laptop through its own 127.0.0.1. Diagnose the machine running the core rather than publishing the daemon. Use a direct conversation for testing, and inspect the channel’s error before retrying.
