HiveMind DeltaChat Bridge

Relay a DeltaChat account to a HiveMind hub.

DeltaChat is an end-to-end-encrypted chat that runs over ordinary email. This bridge is a HiveMind satellite whose input and output are DeltaChat messages instead of a microphone. Each incoming chat message becomes an utterance sent to the hub. The hub's spoken reply goes back to the sender's chat. Any HiveMind hub, and the OVOS skills behind it, becomes reachable as an email-based chatbot.

DeltaChat (email)  ⇄  HiveMind-deltachat-bridge  ⇄  HiveMind hub (hivemind-core)  ⇄  OVOS skills

Prerequisites

• A running HiveMind hub (hivemind-core) reachable over the network.
• A HiveMind access key + password for this bridge, issued by the hub with hivemind-core add-client.
• An email account for the bot (address + password). DeltaChat works with any IMAP/SMTP mailbox. The address is what users message to talk to the hub. The easiest option is a chatmail account (instant, bot-friendly): see docs/accounts-and-chatmail.md for how to get one and the full operator walkthrough.
• The native libdeltachat / deltachat-core library installed on the system. The deltachat Python package binds to it.

Install

pip install HiveMind-deltachat-bridge

Or from a checkout:

git clone https://github.com/JarbasHiveMind/HiveMind-deltachat-bridge
cd HiveMind-deltachat-bridge
pip install .

This installs the hm-deltachat-bridge console command.

Quickstart

1. Register the bridge on the hub (run where hivemind-core is installed):

hivemind-core add-client --name deltachat-bridge \
  --access-key "your-access-key" --password "your-password"

2. Store the HiveMind credentials so they are read automatically:

hivemind-client set-identity \
  --key "your-access-key" \
  --password "your-password" \
  --host "ws://192.168.1.100"

(set-identity ships with hivemind-bus-client, a dependency of this bridge.) Alternatively, pass --key/--password/--host on every run.

3. Run the bridge with the bot's email login:

hm-deltachat-bridge \
  --email "bot@example.com" \
  --email-password "mailbox-password"

4. Send a message. From any DeltaChat app (or plain email), message bot@example.com:

what time is it?

The bridge forwards the message to the hub, waits for the speak reply, and answers in the same chat.

Configuration

hm-deltachat-bridge options:

When --key/--password/--host are omitted they are read from the stored NodeIdentity. If none are available the bridge exits pointing you at hivemind-client set-identity.

Troubleshooting

• NodeIdentity not set: run hivemind-client set-identity, or pass --key/--password/--host.
• No reply to messages: confirm the hub is reachable and the access key is authorized (hivemind-core list-clients), and confirm an OVOS pipeline produces spoken answers.
• Mailbox login fails: verify IMAP/SMTP is enabled for the bot mailbox, and that the password is an app password where the provider requires one.
• ImportError on deltachat: install the native libdeltachat / deltachat-core for your platform.
