MyHome is a proprietary bus system for home automation developed by BTicino. HSYCO fully integrates with MyHome using the OpenWebNet (OWN) protocol.
HSYCO supports all MyHome devices and features that the OWN protocol officially supports, including lighting, automation, scenes, AUX and CEN addressing, the temperature control unit and burglar alarm unit.
The bus architecture can be arranged as a single bus or with a riser and several local busses.
Communication
HSYCO supports the Ethernet IP connection to MyHome through IP-based OWN gateways, including the F452, F453, F454, F453AV, MH200 and MH200N.
HSYCO also supports the L4686SDK module through an USB connection and an associated virtual serial port.
Gateway Configuration
The OWN gateway must be configured to allow open OWN connections from the IP address assigned to the HSYCO server.
L4686SDK Module
The L4686SDK interface module is connected to HSYCO using a USB cable.
The operating system creates a virtual serial port; its name depends on your HSYCO server configuration, and should be ttyUSB0 if there are no other devices connected to the USB ports.
You could also use the ftdi-n-n.n alias, that is unique for each physical USB port on the server. In this case, you should also list the full device name in the CommPortsList parameter.
L4686SDK Limitations
- L4686SDK firmware version 1.20.0 or later is required
- Not all protocol frames are supported. The I/O server has been tested with the following functions: scenarios, lights, automation, temperature control, AUX and CEN plus
- Check the L4686SDK documentation to know which functions are actually supported, also based on the L4686SDK firmware version
- The clock read and sync functions are not supported
- HSYCO only support the L4686SDK module on a single main bus; private raiser buses are not supported
- the USB connection cable should never be unplugged during normal operations. If the cable is unplugged, HSYCO will not be able to restore the connection to the L4686SDK until it is manually restarted.

Note on temperature control units
The 4695 four zone temperature control unit uses a zone address for the control unit itself. This address has to be marked as a special address in the tempzones parameter, enclosing it in round brackets.
For example:
tempZones=(32);33
defines a central unit having address 32, and an additional zone with address 33.
The MyHome I/O Server supports only one central unit for each SCS riser bus.

Because the MyHome burglar alarm panel cannot be directly controlled via OpenWebNet commands, there are no standard control objects for this system.
