    How To Receive La Crosse TX7U on RFXrec433?

    I currently have 2 RFXrec433 receivers connected over serial IP to Raspberry Pi. I use them to receive all the Oregon Scientific Temperature Sensors. Unfortunately Oregon Scientific seems to have stopped making their temperature sensors. I was looking at La Crosse 433MHz temperature sensors to be able to keep adding on. Can anyone tell me how to receive from the La Crosse TX7U? Any special configuration on the RFXrec433?

    Thanks for any help!

    enable Lacrosse on the receiver config page.
    Use the latest RFXtrx433 Type1 firmware. Check the current firmware version using RFXmngr in case you have to go back.

      Thanks so much. Right now I have two receivers connected to the RFXCom

      As you can see RFX 1 is hardware 1.3 RFXtrx433E and RFX 2 is hardware 1.0 RFXtrx433, is it ok to update both of these to RFXtrx433 Type 1 - 1025 (They are already at 1025 but of Receive Only, which is fine, since I have nothing to control. Is the transceiver function needed for La Crosse temperature sensors?)

      Last question, do you have a recommendation for simple wireless temperature sensors to replace the Oregon Scientific ones that are no longer being sold? Does does anyone know why they have discontinued the Oregon Scientific Temperature sensors?

      Thanks again!

        One of your devcies is a RFXtrx433E which can be flashed with Pro1 firmware. This supports the Ambient weather F007TH
        https://www.amazon.com/Ambient-Weath.../dp/B00C3HBRIW

        see chapter 2 in the RFXtrx User Guide for the list of supported sensors.

          Awesome... Out of curiosity, since the Ambient weather F007TH is a 433 MHz temperature sensor, why will the RFXtrx433E be able to decode it but the RFXtrx433 not be able to?

            Pro1 firmware cannot be flashed in the RFXtrx433 due to the small memory of this device.

              That I understand, what I am asking is why can the Pro1 firmware on the RFXtrx433E be able to decode a 433 MHz Ambient weather F007TH Temperature sensor but the Type 1 Firmware on the RFXtrx433 not be able to decode that same sensor?

              Is it simply that the code for decoding the sensor just does not exist on the Type 1 Firmware on the RFXtrx433 and not a technical radio limitation?

              (I am somewhat new at this and just trying to understand how it all works)

                You are correct, the RFXtrx433 is technical able to decode the sensor but this F007TH protocol cannot be added to the firmware.
                The old Type1 and Type2 firmware are frozen as there is no memory avsailable to add new protocols.

                  I get it now! Thanks so much! Since I would like to have two receivers (one in each part of my house). Is it possible for me to purchase a RFXtrx433XL? I do not see them for sale.
