# What is it

I have a few home automation devices on my todo list like sensors, lights etc.

Usually I am using ESP32s connected to my MQTT broker for these things, so I decided to write a basic firmware with all the necessary features to create a starting point for developing the individual firmwares

# Used Versions etc

ESP-IDF: v5.0.1

Hardware: ESP32-WROOM-DA with 4MB

# Features

- System info on startup

- Wifi with settings from flash

- Time sync from NTP server

- MQTT

- Simple command receiver for MQTT commands

- OTA firmware update with rollback

# Notes

- PSRAM is enabled, but ignored if not found

- The system stops at a panic and is not rebooting!

- For HTTPS Requests: Server cert verification is DISABLED! :warning:

- FW version check on OTA update is disabled

# TODOs

- Handling of WiFi disconnects and mqtt reconnect

- Error handling, not simple ESP_ERROR_CHECKs

- Wrapper for accessing NVS

- Namespacing of NVS Keys

- Handling ot multiple mqtt subscribes

# WONT DO

- Firmware signing

- Secured MQTT

- Configurable timezones
