    Hello guys,

    I had the same problem with st=fail, also with this output: "Error sending command, check your hardware/device (blablabla :D)". I can give you here my hints, maybe they will help you. First of all I am using the latest beta domoticz and beta mysensors library v1.6.

    I am using two types of nrf24L01+ (with built-in antenna and external). For built-in antenna I am using #define RF24_PA_LEVEL_GW RF24_PA_HIGH in my sketches, BUT for external I need to lower the power because Arduino cannot provide enought current for it (even with attached capacitor): define RF24_PA_LEVEL_GW RF24_PA_LOW. I had this st=fail when I was using HIGH settings for nrf with external antenna, but now it is fixed. Also make sure that you have enough coverage.

    I have Arduino Mega2560 installed 1 week ago with 16 channel 12v relay board together. I had the the same problem like you "Error sending command, check your hardware/device". Two days ago I realized that maybe there is a problem with my powering my gateway. I have RFXtrx433, APCups and Ethernet Arduino Uno gateway connected to Raspberry Pi USB. I connected my MySensors gateway separately via 5V charge to the wall socket and this error problem is gone. Conclusion was this that my Raspberry couldnt supply enough current for all attached devices. Now I am planning to install PiHut USB hub with external power supply and move all connected USB interfaces to it and then just with one connection cable to my raspberry (maybe RFX will work better :) we will see).

    Update us if these two hints helped you ;D.

    Cheers
    Maciek

    @macieiks Could't find what my problem was. I've tried changing the gateway code to the sensor, same issue, change the radios, the same thing.

    I ended up downloading again the Mysensors library, the same issue, i then changed the baud rate for the debug and serial gateway to 19200 and that seemed to solve the issue, i can now issue commands to the nodes, thanks for the help.

    My sensor and gateway are all Pro mini, 8v 8Mhz, i remember now that i've read something in the forum, but can't find it now.

    Domoticz, mysensors 2.3.1, RFM69 and RF24 sensors

      This may come into a great help, I have two external antennas that I thought where damaged since arrival, maybe this is the problem. I'm going to try this next week.

      Although, this still makes me thinking of distance, the error appears with the hardware separated by +- 3m with no obstacles .

      Cheers

      @hugo_pn Is's possible to see the sketch? Im insecure where to alter the sketch.

        Hi,

        I'm trying to find it. As soon as I do and if I do I'll tell.

          Hi,

          Can't find the specific line. The most similar one is in the MyConfig.h line 115

          #define RF24_PA_LEVEL_GW RF24_PA_LOW

          Going with the GitHub file I don't even find it...

          Where exactly did you change the mentioned above?

          Thanks

          Hugo

          P.S. I can't find the V 1.6 library for my sensors. That's why I mentioned github

            1.6 is the default branch when you go to the github project.

                st=fail means the gw radio doesnt reach the node.
                It can be a power issue (search the forum) which can be fixed with caps and/or other power.
                It can be a range issue and then you need a repeater.

                  @sundberg84 The node is 2 meters from the gateway.
                  It most be an power problem. Is it with the gateway or node?

                    Hi!
                    Can be both (or even worse, faulty hardware/bad fake nrf radios).

                    I power my gateway through USBCharger and have a 4.7 + 47 uF cap paralell on VCC/Gnd.
                    On my nodes i use a single 4.7uF cap VCC/GND

                    In best case its just one of your radios thats bad or misswired... check wiring and/or change the radios if you have another one.

                      @sundberg84 On my gateway (nano) is an 4.7 uF og it is connected with USB to the domoticz. How can I do it different?

                      Im getting this from the node. It reads okay.

                          I had this problem due to range but 2m shouldnt be any problem... so strange you can recieve but not send.

                          Some things to consider if someone else doesnt know better than me:

                          • Change radios if possible
                          • Send commands without relays attached (to see if there is some spokes or disturabnce from relay)
                          • Connect MYSController to debug if possible

                          Whats your node ID on that node?
                          Im not good reading those serial lines but if they are beginning with 0 its like its sending to the gateway!?
                          In my case when i send: 103;1;1;1;2;1 where 103 is node ID, Child(Relay) 1, MsgType = 1 (Set), Ack = 1 (yes), 2 = V_LIGHT, 1 = On

                            How can i Send commands without relays attached? Where i see log from the gatway?
                            I also tryed change radios. No change.

                              Sorry, Domoticz logs and hardware doesnt provide any info about the radio traffic. MySensors NodeID and Domoticz ID is not the same either.

                              If you disconnect the relay from your Arduino you should still be able to send the switch command and with this the relay disconnected it doesnt make any power spikes that could interfere with the radio.

                              Could you please post your sketch and logs from the gateway again... I cant seem to figure this out.

                                  How do i change the node number?
                                  It select node 2 all the time with new nodes?

                                  In the sketch they are set to AUTO.

                                  Im using standard sketch from the libery.

                                    Change: gw.begin(incomingMessage, AUTO, true);
                                    To: gw.begin(incomingMessage, 3, true); (If you want 3 as node id)

                                      Made a test (with the external antenna on Gateway) the other day and this is what happens.

                                      I put the nrf24 with the external antenna attached to the Nano and Upload the Serial Gateway Scetch onto it.

                                      Ran The Serial Monitor and get this

                                      0;0;3;0;9;gateway started, id=0, parent=0, distance=0

                                      0;0;3;0;14;Gateway startup complete.

                                      I remove it from the PC, attach it to the Raspberry Pi I give two switch commands that work, then at the third attempt the message comes to life "Error sending switch command, check device/hardware !"

                                      Back to PC this is what I get.

                                      0;0;3;0;9;radio init fail

                                      After a few minutes It's OK again like the beginning.

                                      Thanks

                                        It (radio init fail) means that when you power it up (connecting it back to PC) it cant initialise radio.
                                        Mostly this is = check wires and/or power issues.

                                        Actions:
                                        Check wires, check wires and check wires :)
                                        Try powering your nano without the relay attached if possible (and see if you get Radio Init fails)
                                        If not - power your relay seperatly if possible (relay often create interferance with radio).

                                          Thanks for the reply, the thing is that I'm powering the Nano via USB from the raspberry Pi (serial Gateway with the external antenna).
                                          The wires I don't think are the problem because it works with the integrated antenna.

                                          Can I power Up the Nano with the Raspbery Pi USB and a 5V Transformer with out burning everything?

                                          From what I remember, parallel tension doesn't sum up, but the current does. Wright?

                                          Will I damage everything, including the Raspberry?

                                          Thanks
