    If you have used this same sensors as a test in the past you may need to clear the eeprom data also.

    Just a guess...

      @manutremo thanks, I have used the parselink text utility but I should have paid more attention
      mm Ive used the same hardware but never got it working. .. your right maybe its stored a dud nodeID.. Looking at the docs https://www.mysensors.org/download/sensor_api_20 I can set a nodeID manually.. I'll give that a go

        Here's the clear eeprom sketch if you need it.

            @manutremo , you hit it bang on.. The NODE_ID wasnt being sent, setting a node id to a number using
            #define MY_NODE_ID 42
            worked.

            Curious, so I can debug this myself in the future, which line indicated the NODE_ID was blank?
            was it this line?
            mysgw: TSF:MSG:READ,255-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0:

              @Angelo-Santagata happy to know that you got it working. Yes I think that's the line which in the log parser showed an empty payload. It would be interesting to know why the gw is returning an empty payload when an ID is requested, though, since that's not usual behavior with the default settings. Let us know what you find out!

                If there is no controller assigning an ID, the gw can't make up one out of nothing. 😀

                  That's certainly the most probable cause, Angelo didn't mention any controller so I assumed there is one... which controller are you using (if any) Angelo?

                    There could be a controller but if it is not assigning any ID is it just as it wasn't any 😁

                      Yes, the fact that it works with a static node id seems to point in that direction - should that not be the case, i sincerely wouldn't have a clue on where to look at.

                        Hi all,

                        ok this is the embarrassing bit, no the controller wasnt attached.. Im using home assistant and what I didnt realise that was that a) the controller sends the IDs and b) the controller couldnt talk to the Gateway..

                        BTW Why do we need a controller to assign the unique sensor IDs? I thought the Gateway would do this?

                          @Angelo-Santagata the gateways are designed to be stateless. The stateless design makes it easy to implement a gateway on low-power hardware. It also makes it easier to correctly implement and verify the gateway functionality, and to troubleshoot if there are problems. If gateways had to remember which ids had been assigned, they would no longer be stateless.

                              @angeloS thanks. I agree. I can't take credit for it though, most of the stuff was designed before I found the project :)

                                  Does anyone have suggestions on a clearer log message? One that would make it easy to understand what is happening? If we could make the log clearer, other people could understand the reason quicker, saving time and frustration.

                                    @mfalkvidd In my case I think if the log had said, No Controller provided SensorID, that would have been my first clue

                                      @angeloS Fully agree - a warning instead of just sending a message with an empty payload would have been easier to spot. Maybe something to propose in Github?

                                          We could add a sample message, in the troubleshooting guide, when the node has no Node ID and the gateway is responding an empty message, so a Node ID must be defined in the sketch
