# LightHub is Flexible, Arduino-Mega based SmartHome controller It allow to connect 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 LED and AC DMX-512 dimmer boards * 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 Where is possible both, to configure local control/mapping between inputs and outputs (light, floor heating thermostats) and remote control from Openhab or Openhab2 Smarthome software Scalability 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 and propagate commands across network Prease refer our Wiki for insructions.
