⁠Galaxy SIA Notification Server for Honeywell Galaxy

A lightweight, self-hosted Python server that receives SIA protocol messages from Honeywell Galaxy alarm panels and forwards them as push notifications to your phone or computer.

⁠Features

• SIA protocol support (Levels 0–3)
• Honeywell Galaxy Flex compatibility
• Honeywell Galaxy Dimension compatibility
• Real-time push notifications via ntfy.sh⁠ — free, no account required
• Telegram, Pushover and webhook providers included
• Extensible notification provider plugin system
• Optional heartbeat monitoring with connection-loss alerts
• Runs on Raspberry Pi, router, NAS, Docker or Windows
• No cloud subscription required — fully self-hosted

⁠Docker

This image is available for:

• linux/amd64
• linux/arm64

The container uses an external sia-server.conf file for account and notification configuration, so your configuration is kept separate from the image and persists across image updates.
