Sure 433 is an open frequency and subject to a lot of noise and other transmitting devices but it seems strange if you only get one out of 20. I transmit data (70 bytes four times a second) about 25m with antenna only on the receiver and in a couple of days I have maybe 2-3% loss. The product exists in two versions, the RFXtrx433 using a RF frequency of 433.92 MHz and the RFXtrx315 using RF frequency of 310 MHz or 315 MHz. First the RFXtrx device has to be plugged to the Vera using an USB link.
