Enabling WhatsApp on Hermes Agent self-hosted: three pitfalls (and how I overcame them)

I wanted a simple thing: to send a message to my AI agent via WhatsApp. The Hermes Agent, from Nous Research, promises exactly that — you spin up the gateway and talk to it via Telegram, Discord, Slack, WhatsApp, Signal, or email. In theory, it’s one command: hermes whatsapp

.

In practice, I ended up struggling until I discovered the simplest alternative. This post is an honest account of what I tested, what didn’t work, and what did work — with real logs. If you run Hermes in Docker (especially within an unprivileged LXC container with data on NAS, like me), you’ll probably hit the same three pitfalls.
