The FS20 / FHT system by ELV is currently the most successful wireless home control system in the low cost sector. This arises from the large number of components and the continuous expansion of the system. But the relatively low price, the comprehensive home control systems far below the price of such EIB systems permits, plays a crucial role.
This FS20 modul is based on CULFW by Rudolf Koenig and supports a wide range of protocols:
- FS20: send/receive
There are numerous FS20 devices, all of them are fully supported. - FHT: send/receivey
Communication to the FHT80b is supported. - S300: receive
Examples of such devices: S300TH, KS300-2 - EM1000: receive
Devices: EM1000FM, EM1000GZ, EM1000WZ - HMS: receive
Devices: There are numerous HMS devices, all of them are fully supported. - ESA2000: receive
- Lacrosse TX2/TX3: receive
Connection
The RFM12 is connected to the MCU like in FSK Mode with a small difference. The output FSK/DATA/nFSS signal (Pin 3) is connected to one of the INT pins of the MCU.
The software uses the digital filter of the RFM12. In order to receive near and far sender as well. To improve sensitivity on short and long distances the C_arssi capacitor needs to be replaced with a value 150 pf.
