BLECM Development Kit vs HA! I'm Home!

Microchip's BLECM (Bluetooth Low Energy Client Module) Development Kit is designed to enable you to quickly and easily connect an embedded system for monitoring and control using this iPhone application which also serves as a gateway for remote monitoring/control with a cloud-based server, such as Amazon Web Services(AWS). This will reduce the learning curve and help you get connected using Bluetooth quickly. The BLECM Development Kit is available from Microchip Direct.

HA Im Home detects when you arrive home and instantly triggers your Home Assistant automations — before you even reach the door. HOW IT WORKS The app uses a combination of GPS geofencing and barometric pressure (elevator detection) to know you're almost home. It then connects via Bluetooth Low Energy to a Mac Mini running the HA Im Home daemon, which securely notifies your Home Assistant instance. No cloud servers. No subscriptions. Everything stays on your local network. FEATURES - Automatic arrival detection via GPS + elevator pressure drop - Bluetooth Low Energy — fast, battery-friendly - HMAC-SHA256 authentication — cryptographically secure - Works with any Home Assistant automation - Presence sensor per user — supports multiple family members - Runs silently in the background REQUIREMENTS - Home Assistant instance on your local network - Mac with Bluetooth (always-on, e.g. Mac Mini) - HA Im Home integration installed in Home Assistant - HA Im Home Mac daemon running on your Mac PRIVACY Your location never leaves your device. Authentication secrets are stored only in Home Assistant — never on any external server.
