Why doesn't Hermes Agent speak in the Signal group? By default, the group will not be monitored, and the SIGNAL_GROUP_ALLOWED_USERS will be assigned first

Hermes Agent can be used in Signal private chats, but when entering the group but not speaking at all, this is usually not a broken bridge, but the Signal group is closed by default. The official documentation is very clear: to allow Hermes to listen to group messages, you must configure SIGNAL_GROUP_ALLOWED_USERS, and if you don't fill it in, it is equivalent to disabling group chat.

How to open a group chat

1. Configure SIGNAL_GROUP_ALLOWED_USERS=groupId1,groupId2 in ~/.hermes/.env.
2. If it's just a test, you can temporarily set it to a * so that the bot responds to all the swarms it is in.
3. Keep SIGNAL_ALLOWED_USERS, don't just let go of the group and not let go of people.

Why is it officially turned off by default?

Because Hermes Agent has terminal capabilities, once the group is too wide, it is easy to turn what was originally just a private chat assistant into a public entrance to the group. The official recommendation is to only allow groups you trust, or to turn off group abilities altogether at first.

So the key to this question is not "why is Signal unstable", but "Signal group chat is not open by default". Just think of SIGNAL_GROUP_ALLOWED_USERS as a whitelist switch, troubleshooting is simple.
