Bin and Img

Each device type has a custom version of the nodemcu runtime. The modules to include are defined in devices folder user_config.h and user_modules.h. This changes infrequently, only when a new module is required from the nodemcu source. This is generated and flashed using the build_nodemcu.sh script.

Each device type also has a img file with it's Lua source code. This changes frequently. This is generated using the build_src.sh script.

All files are stored in the relevant devices folder.

Mosquitto Bridge Configuration

As the system uses ESP8266, they do not work well on TLS. The solution to this is to have a local broker running with a secure bridge to the platform. This can run on a RPi or router that supports MQTT bridges.
