            Between the above two error codes, there are several similar code with different “PCM surroundNo.” end (21, 40, 41, 50, 51, 71) like:

              @James thank you for reporting the bugs. I will try to fix them soon.

              The code doesn’t save the photo into the file. The image data base64 encoded is passed from the camera module to the node_helper. I could add this, but am I afraid of filling up the space on the RPI.

              Which provider did you configure the nodemailer with?

                @alexyak Hotmail. And one thing I need to confirm with you is that “email & password” are filled in between “‘’” or “<>”?

                  @alexyak bug report:

                  1. pm2 won’t restart MM after a reboot and press Alt+F4 for the first time. (This occurs randomly, I tested for several times even if not the first time to press Alt+F4 after a reboot)
                  2. I need to run “pm2 restart mm” to get MM restart again.
                  3. After this sometimes the modules not work. I’m not sure which one is. camera or voicecontrol? Errors ouputs as follows:
                  Expression 'r' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2097
                  Expression 'PaAlsaStreamComponent_FinishConfigure( &self->capture, hwParamsCapture, inParams, self->primeBuffers, realSr, inputLatency )' failed in 'src/hostapi/alsa/pa_linux_alsa.c', line: 2731

                  IOError: [Errno Unanticipated host error] -9999
                  
                  1. Finally, I received Selfie, that the email & passward need to be filled in without “<>”. You may change the sample config code in the readme.md as well :)

                  Thanks,

                        Tested the voice control + camera module today and got both working. Thanks @James for the tip on the missing config curly brackets. Was starting to drive me crazy as no JS Linters were picking it up.

                        For future reference, the voice control module now comes pre-packaged with the three camera commands by default in the voicecontrol.js file, so in your config.js file, you only need to add:

                        {
                            module: 'voicecontrol',
                            position: 'bottom_left'			
                        },
                        

                        In fact, if you do add the config: definitions and any keywords to your config.js file, it actually overrides the three default camera commands. With that said, is it best practice to add additional keyword commands to voicecontrol.js OR to remove the defaults from voicecontrol.js and place everything in config.js?

                        I also get the ALSA lib error messages in Terminal after quitting the mirror, as well as the countdown bug James mentions after taking a picture, but everything seems to work and I DID receive the email no problem (using Gmail, after following @alexyak’s instructions on “Allowing Less Secure Apps” and “Allowing Access To Your Gmail Account”).

                        All in all, awesome work, Alex! Thrilled to now have 3 of your modules running on my mirror as I’m running motion sensor too!
