I recently bought a used RFXcom (with temperature sensors), it had wireless RFXCom temp sensors connected to it. The wireless temp sensors work on a (X10 protocol). Within the rfxmanager I could set the RFXCom protocol to X10 and it was able to read the data from the older RFXsensors. I was looking for an upgrade for my setup. So I went looking for newer temp/hygro sensors. I came across the Bresser Hygro/thermo wireless sensors. Now I would like to connect this sensor to my RFXcom, however that did no go as easy as I hoped to. The rfxmanager does not show any data from the new sensor. I also can't find on which protocol the new sensors works.
So my question is, how do I setup my RFXCom for a new sensor?
