The ITGW-433 Lan gateway can only be used with intertechno radio receivers.
If you wish to operate blinds/shutters or garage doors controlled by Somfy or other third parties, you must install an intertechno radio receiver in parallel.
For example ITL-500 (1204316 1) /ITL-1000 (1204305 1) , then it will also work with ITGW-433.
