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.
