|
===============
|
|
|
|
This repository is a storage for my mqtt and IoT (( ͡° ͜ʖ ͡°)) playground.
|
|
|
|
|
|
Hardware
|
|
--------
|
|
|
|
Current tests involve NodeMCU ESP12-E/ESP8266 boards. Switch is activated with
|
|
GPIO0 (FLASH button on NodeMCU) and light is connected to GPIO2, where blue LED
|
|
is directly connected on ESP-12E module.
|
|
|
|
|
|
Software
|
|
--------
|
|
|
|
Mosquitto contained in docker is used as a broker. For proper TLS you need to
|
|
create self-signed certificate and store its SHA-1 fingerprint in
|
|
`common/common_config.h`.
|
|
|
|
ESP8266 code uses [patched slaff's
|
|
fork of Sming framework](https://github.com/informatic/Sming/tree/patch-1).
|
|
(For axTLS support) Set your Wifi configuration in `common/common_config.h`
|
|
(used by both `switch` and `light`)
|
|
|
|
|
|
Thoughts
|
|
--------
|
|
|
|
Oh my, that's slow.^W^Wquite fast, when patched properly.
|
|
|
|
**WARNING!** `Sming.reset();` jumps to (serial) bootloader right after flashing.
|
|
This causes OTA to fail with `wdt reset`. External RESET assert is required after
|
|
flashing.
|
|
|
|
TODO
|
|
----
|
|
* Store configuration (credentials, broker IP, maybe endpoints?) in
|
|
flash memory
|
|
* [!] Fix OTA
