    Weird. It sure looks like it is connected from the config screen dump.
    How does the "Advanced" tab (or equivalent in UI7) look like for the MySensors Gateway device?

      Here are screen captures of three of the four tabs in the advanced section. There was nothing under the commands tab.

        Try setting ComFailure to 0 and save device/reload.

            @hek Do you know why this fixes it?

            Does vera not retry if ComFailure >0 ??

            On my UI7 test box and test g/w, if I turn off the g/w for whatever reason I find I need to restart luup on Vera to get it to re-establish connection to the g/w.

            So I wonder if it does retry after a period ( which ive never been patient enough for )

              I have no idea why it works. As you say.. it probably doesn't retry if this number is larger than 0. I had the same problem with my Alarm system.

                To fix that error someone, needs to update the plugin and include this line:
                luup.set_failure(false)
                This way the can't detect message won't be displayed anymore.

                    i had the same issue and it was the serial chip was not apropriate and won't comunicate. ch340,fake ftdi... that kinds won't comunicate propely and cause problems. after change to a FTDI chip all works good

                    i'm a arduino fan .Even sometimes don't undestanding how to use it :P

                      Thank you @Tmaster. I put this project away a while ago, and just recently realized after some unrelated reading what the issue must be with this adventure. I'm pretty sure this is what is going on and just have not had the time to get back to it.
