Hi everyone! I’ve been working on a DIY security system using an ESP32 and a PIR motion sensor. I followed this tutorial on ESP32-based motion detection with email alert:

It helped me get the motion detection and alerting part working using email, but I’d like to shift to something more local and privacy-friendly, without relying on cloud services. Now I’m trying to figure out the best way to send alerts locally either by triggering an HTTP request to a local server, using MQTT, or implementing SMTP directly on the ESP32.
Have any of you implemented something similar? I’d love to hear your suggestions on lightweight, secure, and fast methods to handle local alerts in a home setup. Bonus if it works well offline and preserves data privacy.
