It may operate both:
* On [especially designed hardware board](http://www.lazyhome.ru/index.php/featurerequest) 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](http://controllino.biz/)
(Controllino and ESP8266 is not tested enough and in experimental stage yet)

Lighthub allows connecting together:
* Contact sensors (switches, buttons etc)
* Analog sensors (Leak detectors, Knobs etc)
* 1-Wire temperature sensors (up to 20 on single bus)
* Temperature/Humidity/CO2 sensors: DHT22, CS811, HDC1080
* Standard nonexpensive Relay board with TTL inputs, [like this](http://ali.pub/2zlosh) to control AC powered lamps, floor heaters, boilers etc
* [Standard nonexpensive LED dimmers](http://ali.pub/2zlokp) and [AC DMX-512 dimmers](http://ali.pub/2zlont)
* Modbus RTU devices (Currently, are deployed two types of Modbus devices: AC Dimmer and Ventilation set (Based on [Vacon 10 controller](http://files.danfoss.com/download/Drives/Vacon-10-Quick-Guide-DPD00714F1-UK.pdf))
