spejsiot

This is the repository of hswaw spejsiot project, meant to IoTize EVERYTHING easily.

This includes simple framework for building appliances compatible with Homie MQTT convention, based on cheapo ESP8266 SoCs and Sming.

It currently supports most of Homie protcol (with homie/ prefix replaced by iot/), OTA and preliminary SSL support. (provided by Sming itself, currently not enabled)

Sample application is present in switch/ directory. (simple relay device) For more information take a look at project wiki page.

Getting started

# Create relevant environment variables in your ~/.bashrc
cat >> ~/.bashrc <<EOF
    # ESP8266 toolchain setup
    export ESP_HOME="$HOME/esp-open-sdk"
    export SDK_BASE="$ESP_HOME/sdk"
    export XTENSA_TOOLS_ROOT="$ESP_HOME/xtensa-lx106-elf/bin"
    export PATH="$XTENSA_TOOLS_ROOT:$PATH"
    
    # Sming setup
    export SMING_HOME="$HOME/Sming/Sming"
    export ESPTOOL="$ESP_HOME/xtensa-lx106-elf/bin/esptool.py"
    export ESPTOOL2="$HOME/esptool2/esptool2"
    
    # This is for Wemos D1 Mini and some NodeMCU boards
    export ESPPORT="/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0"
    export COM_PORT="$ESPPORT"
    
    # Make flashing slightly (4x) faster.
    export ESPBAUD=460800
    export COM_SPEED_ESPTOOL="$ESPBAUD"
EOF

source ~/.bashrc

# Setup ESP8266 development environment (some additional packages may be needed)
git clone --recursive https://github.com/pfalcon/esp-open-sdk.git $ESP_HOME
pushd $ESP_HOME && make && popd

git clone https://github.com/raburton/esptool2 $ESPTOOL2/..
pushd $ESPTOOL2/.. && make && popd

# Setup Sming environment
git clone --recursive https://github.com/SmingHub/Sming $SMING_HOME/..
pushd $SMING_HOME && make && popd

# Build test spejsiot app
git clone https://code.hackerspace.pl/informatic/spejsiot
cd spejsiot/switch/ && make flash

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.

Configuration

Basic node configuration (MQTT broker IP, 802.11 credentials) is present in common/common_config.h.

TODO

  • Store configuration (credentials, broker IP, maybe endpoints?) in flash memory
  • Docs, ffs
