    I have the problem that I always get this error: !TSM:FPAR:NO REPLY

    Once it worked briefly yesterday.

    What have I tried everything?
    All hardware exchanged - without success.

    Now I have just written two small scripts that send RS485 back and forth. without problems. So wiring has to fit. I spent then in the serial montior the data which the node sends me, there comes some. Then I once tried to display the data that sends the GW, because nothing comes.

    Does anyone have an idea why my GW does not answer?

    @andreas-sieber could you post the debug output from the node and the gateway?

        why don't you use the stable 2.2? Anyway the node is missing the my_node_id define and second it seems the gateway isn't receiving anything, so I guess there is something very wrong in communication

          in the 2.2 the same problem, i have now updagradet to alpha.

          When you have a solution on 2.2 i will downgrade. no problem!

          Guys you are good! I had set the mynodeid. But befor i include the my sensors.. that's the mistake..

          hour of hour to search... thx!

            Is it possible, or will it be possible to build a combination between wired and wireless nodes?

                Consequently the gateway can't find any device.
                I have tried also with RS485 with different baudrate. Finally I just connect my USB TTL directly to ouput pins, but always same result.
                How to fix it?

                  @Pavel-Polititsky
                  To me this looks like you mixed between-node communication (RS485) with debug output (and maybe also serial output of the gw).
                  The corresponding serial interface for RS485 should be dedicated to RS485 exclusively.

                    Hi,
                    first of I have to thank you for your effort on this project! It helped me a lot.
                    In my house I would like to build 2 networks, one with serial gateway with RF24 for ground floor and outside. Second will be in cellar and I was thinking about Ethernet gateway (W5500) but sensors will be connected via RS485. Do you have code for that? On the video it looks like that in the box on right side it is something like this.

                          @giebek could you describe the problem, what your setup looks like, and what you have tried so far to troubleshoot it? There are 137 posts in this thread so it is a bit hard to figure out which problem you are referring to.

                            Imo this indicates your node doesn't have a NodeID yet. When using RS485 you have to assign the ID's manually in the sketch, auto doesn't work... (e.g. #define MY_NODE_ID 123)

                              Thanks for the answers.
                              And even more thanks to the rejoe2

                              #define MY_NODE_ID 123

                              it helped 100% the transmission went, domoticz sees children.

                                hello MySensors friends,

                                I am currently making a node based on an arduino Mega 2560 with transport via RS-485, the build page says that we should use the MEGA pin 46 & 48, I was wondering if I would like a reference for this. in the sketch.
                                Second question; can I use pin 47 for the DE pin with:

                                #define MY_RS485_DE_PIN 47
                                

                                I haven't tested anything yet, so actually I just ask a lazy question ;)

                                  Hello, I would like to better understand the concept here. It sounds like we still need a gateway connected to a controller (serial, Ethernet, WiFi, etc.) but the interface between gateway and multiple nodes is over wired RS485 serial interface. Please confirm. Thank you for your great efforts!

                                    @apl2017 Yes, also for RS485 variant you'll need a gateway. Only the communication between the gateway and the other nodes is handled over RS485, connected to a second (typically software) serial interface (for remote nodes, you may just use the hardware serial interface to connect the RS485 transceiver, if you do not need debug output; but imo this option is not recommended for beginners).

                                    Controller: FHEM; MySensors: 2.3.1, RS485,nRF24,RFM69, serial Gateways

                                      I have it working, so you don't have to adjust anything for a Mega, and pin 47 for DE also works!

                                        in a node how many children can put rs-485
                                        thanks good work

                                          and it can have blockages if there are sensors that function or even time
                                          thanks
