      Every day at 07:00 my M1 sends me a text message that confirms the text messaging process is working. This has worked flawlessly for several years. I had to implement a Google  App Password back in summer 2024 to keep it working but have experienced no problems before or after this, receiving several text messages every day as various rules sent messages in response to gate and door openings, freezer temperatures, power failures etc.

      The last message I received was late on the evening of February 23. Since then, no messages. All other aspects of the M1 are functioning fine. System logs confirm this.

      Troubleshooting to date:

      1. Using the Test button on the M1XEP Setup window fails. It worked previous to this.

      2. Confirmed Google’s recommended Gmail port and server URL/IP have not changed.

      3. I tried using Gmail’s alternate port without success.

      4. My Google account and email have not changed.

      5. I deleted the relevant Google App Password and asked Google to create a new one. No success after updating the M1XEP with the new password.

      6. Successfully tested the cell service email address I use to receive M1 messages and send them to my iPhone as SMS. Did this with both a Gmail account and an ISP provider account. Worked quickly and perfectly.

      Out of ideas. Does this sound familiar or any suggestions for me to pursue?

        Are you running M1XEP Firmware 2.0.51? If not please try updating. In the M1XEP Setup under the TCP/IP Setting tab what do you have for the Primary DNS Server IP Address? You might want to try using your Gateway as the Primary or Google 8.8.8.8 and leave the Secondary blank.

          Support for apps sending to Google email has stopped working for other people and platforms. They are requiring stronger authentication methods. There is some discussion going on about this with the Universal Devices controllers.

            Problem solved. Updated the M1XEP to 2.0.51. Did not have to try anything else. Turned on update checking each time ElkRP2 is started to remind me to update.

            During my research, as Guy noted, there is a lot of information available about Google restricting 3rd party apps from accessing Gmail starting in summer 2024. Sooner or later I expect this may end up impacting M1 owners using Gmail for text messaging.

            Thanks Brad and Guy!

              Where do I look to see what version of M1XEP Firmware I have?  The program shows these Main Program 2.0.41

              Thanks,

              John

                OK, I got the bootloader and firmware updated. Email works, but……

                When I start ELKRP2 and connect to network, I get the yellow warning that says XEP Setup has conflicts.  I tried:

                -View differences, it save it cannot display them

                -Send checked items, save and restart still comes back

                -Receive checked items, save and restart, still comes back

                -Delete checked items, says it cannot do it.

                – I also went in MEP Setup and checked all the tabs for any possible new settings, nothing.

                How do I clear this?

                Thanks,

                John
