is Flexible, Arduino-Mega/Arduino DUE/ESP8266 open-software and open-hardware SmartHome controller. RU HOME-site RU It may operate both: * On especially designed hardware board with 16 optocoupled digital inputs, 16 ESD protected digital/analog Inputs/outputs, 8 open-collector outputs (up to 0.5A/50V), DMX IN/OUT, MODBUS RTU and hardware 1-wire support circuit. * On plain Arduino MEGA 2560, Arduino DUE, ESP8266 and even on Controllino (Controllino and ESP8266 is not tested enough and in experimental stage yet)
Lighthub allows connecting together: * Contact sensors (switches, buttons etc) * 1-Wire temperature sensors (up to 20 on single bus) * Standard nonexpensive Relay board with TTL inputs, like this to control AC powered lamps, floor heaters, boilers etc * Standard nonexpensive LED dimmers and AC DMX-512 dimmers * Modbus RTU devices (Currently, are deployed two types of Modbus devices: AC Dimmer and Ventilation set (Based on Vacon 10 controller) * Simple DMX wall sensor panel like this
Where is possible both, to configure local control/mapping between inputs and outputs (light, floor heating thermostats) and remote control from MQTT enabled software. At the moment, LightHub tested with following set of complementary free software: * Openhab or Openhab2 Smarthome software Openhab provides own native mobile app both, for IoS and Android, and even allow you to use Apple's HomeKit to say “Siri, turn on light in bedroom” but requires some server to be installed (Raspberry PI with Openhabian will good enough) * HomeRemote mobile client Home Remote mobile applicatios for IoS and Android requires just MQTT broker to be working. Any Cloud-based MQTT broker, like CloudMQTT will enough to serve average household, even with free account. * Node-Red Possibly, the best solution to deploy event-based authomation and scripting on top of MQTT/LightHub. The easy to use universal and visual tool to wire many different devices in single system. Having own Dashbord which allow control from web/mobile web, even without mobile apps (but excelent co-working with OpenHab and HomeRemote)
Scalability of Lighthub is virtually unlimited: Setup so many controllers you needed in most convenient places of your house - MQTT broker will allow controllers communicate each other and with Openhab/NodeRed/HomeRemote and propagate commands across network.
Finished portation of project to Arduino DUE and ESP8266 (ESP32 not tested).
Compiled image has been added to compiled/ folder. Flash your Mega 2560
avrdude -v -V -patmega2560 -cwiring -b115200 -D -Uflash:w:firmware.hex:i
or flash your DUE (need to correct path and port, of course)
/Users/<user>/Library/Arduino15/packages/arduino/tools/bossac/1.6.1-arduino/bossac -i -d --port=cu.usbmodem1451 -U false -e -w -v -b firmware.bin -R
Note: binary images usually not up-to-date with recent code. The preferred way, to compile and upload firmware to your controller.
(quite big number of libs required. Use git clone to have your local copy in your Arduino libs folder) Please check updates for all dependences.
For patched libraries, appropriate GitHub repo URL provided:
The normal path to find this file in platformio is: .platformio/packages/framework-arduinosam/variants/arduinoduex
In linux\OSX you can open terminal, navigate to your programming directory, then
git clone https://github.com/anklimov/lighthub.git cd lighthub ``` now prepare project files for your IDE pio init --ide [atom|clion|codeblocks|eclipse|emacs|netbeans|qtcreator|sublimetext|vim|visualstudio|vscode]
Set custom build flags. first make your own copy of template
cp build_flags_template.sh my_build_flags.sh
then edit, change or comment unnecessary sections and source it
nano my_build_flags.sh source my_build_flags.sh
build and upload firmware for due|megaatmega2560|esp8266 board
pio run -e due|megaatmega2560|esp8266 -t upload
Clean pio libraries folder. Try it if you have compilation problem:
rm -Rf .piolibdeps
open COM-port monitor with specified baud rate
platformio device monitor -b 115200
