About iMessage Hermes on a Raspberry Pi
iMessage Hermes on a Raspberry Pi is an always-on AI agent that runs on a Raspberry Pi in your home. It uses the open-source Hermes agent and a real phone number you can text via iMessage or SMS from anywhere. Setup involves handing a guide to a coding agent that performs most of the work over SSH.
Review
iMessage Hermes on a Raspberry Pi takes a different approach to personal AI agents by dedicating a physical device in your home. Instead of running on your laptop or phone, it sits on a low-cost Raspberry Pi, always on, reachable by text message. The project is free and open-source, with a community building various home automation extensions on top of it.
Key Features
- Always-on agent on a Raspberry Pi, reachable via iMessage or SMS using a real phone number provisioned through the Plow Chat API.
- Thread-based communication with pre-approved participants, requiring a verification code to opt in - no open phone number.
- Setup by handing a step-by-step guide to a coding agent that works over SSH, with checkpoints at each stage to confirm success.
- Hermes agent is open-source, letting users build custom applications like family calendars or recipe helpers on connected screens.
- Community Discord for sharing what users build on the foundation.
Pricing and Value
The iMessage Hermes software and setup guide are free. The Raspberry Pi hardware and the Plow Chat API service for the phone number are separate. The Plow Chat API's pricing is not defined in the project's materials; users should check the API provider for costs. The tool itself carries no license fees.
Pros
- Runs on inexpensive, widely available Raspberry Pi hardware, keeping the always-on agent separate from personal devices.
- Uses a real phone number with thread-based verification, reducing the risk of unwanted access.
- Setup process leverages a coding agent to automate SSH steps, and each step includes a checkpoint to verify progress.
- Open-source foundation lets users create tailored home automation tools, with examples like a kitchen dashboard and fridge recipe helper already shared by the community.
- Doesn't require a Mac bridge for iMessage; the Plow Chat API handles messaging directly.
Cons
- No built-in protection against power loss or SD card corruption on the Raspberry Pi; an unexpected power cut could corrupt the agent's state.
- Dependent on internet connectivity - the agent doesn't have local fallback for scheduled tasks or offline access to information like calendars.
- Not well suited for users without command-line or SSH familiarity, or those seeking a fully plug-and-play appliance.
iMessage Hermes on a Raspberry Pi fits technically inclined users who want a persistent home AI agent they can text from anywhere. The open-source nature and community extensions make it adaptable, but the reliance on a stable power and network environment, and the need for some setup effort, may exclude less technical households. It provides a starting point for DIY home automation with an AI agent.
