      I created a script to make it easier to install the Raspbian OS and the agent on a new Pi:

        @Russ said in Raspberry Pi setup:

        /usr/share/triggercmdagent/app/src/installdaemon.sh

        I followed the steps here, but the list of commands is empty right after install. The command output is:

        pi@raspberrypi:~ $ sudo triggercmdagent
        Run installdaemon.sh to install the triggercmdagent daemon so it runs during boot
        Daemon install: false

          @avs2020, it looks like you figured it out because I see commands associated with your raspberrypi computer now. Please confirm.

            It looks like offCommand is never called using this PI/Debian distribution, do you have an update? Did you forget to include this functionality for Linux, it works fine on Windows.

              @George-Hatzisymeon, sorry I never responded to this. I just noticed it because someone upvoted it.

              I just verified that the offCommand commands.json value is supported in the current version of the Raspberry Pi agent. If you were using that version and it didn't work, then maybe you were missing this part:

              "allowParams":"true"
              

              Here's an example entry I just tested. It turns my led strip off if the parameter was off, and if the parameter was on, it turns the strip on and makes the leds green.

                  {
                     "trigger":"Green",
                     "command":"\/root\/killrun.sh leds.py green",
                     "offCommand": "\/root\/killrun.sh leds.py off",
                     "ground":"background",
                     "voice":"green",
                     "allowParams":"true"
                  },

                What I did wrong? It appears:
                E: Unable to locate package https://agents.triggercmd.com
                E: Couldn't find any packageb by glob 'https://agents.triggercmd.com'
                E: Couldn't find any packageb by regex 'https://agents.triggercmd.com'

                I'm a noob, and sorry for my english.

                  @Ar7hur, the URL to download the Raspberry Pi installer is this:

                  https://agents.triggercmd.com/triggercmdagent_1.0.1_all.deb

                  Does that answer your question?

                      @Ar7hur, how do you get those errors? Can you please give me the command you typed, or paste a screenshot?

                          @Ar7hur, no problem. I'm glad you got it working.

                          You could create a trigger that runs shutdown --poweroff but it won't actually power the Raspberry Pi off. Raspberry Pi's also do not support wake-on-lan, so you couldn't power it on from another computer on your network like you could with a PC.

                          The only thing I can think of is you could power the Pi on/off with a relay by connecting/disconnecting the vbus on the 5volt power input with an adapter you could build with something like this, or you could use a smart plug to power it off/on. You could run a command that runs an Alexa routine that powers the smart plug on or off.

                            Hello, first of all thanks for this amazing integration/work.

                            I've a question:

                            Do you know if there's a way to add a parameter over the "commands.json" file in order to make Alexa speak when you execute the trigger? So she'll reply when you do a query. Would be great so it could be integrated with some bash scripts/ansible playbooks.

                            Thank you,
                            Kind regards.

                              @Jorge-Fuentes, yes, there is a way.

                              You can use the Voice Reply field to do that.

                              This article explains how.

                              Basically, put "{{result}}" in your voicereply field and run the sendresult script that the TRIGGERcmd agent installs here:

                              Windows:

                              %USERPROFILE%\.TRIGGERcmdData\sendresult.bat
                              

                              Linux / Mac:

                              ~/.TRIGGERcmdData/sendresult.sh
                              

                              I know you're on a Raspberry Pi, but I'm pasting the Windows GUI editor screenshot just to make sure the concept is clear.

                              f3d13688-7d34-434a-874d-2168e6ef7daa-image.png

                              In the runs list you can see what the "sendresult" script is sending back to the server as the "result" of the command you ran. If you include {{result]] in the Voice Reply field, The TC, TRIGGERcmd, or Trigger Command Alexa skills will say that text when you use one of those skills to trigger the command.
                              eb58845e-a91a-4835-bd03-15f7e9127f74-image.png

                              Instead of making the command in the commands.json file directly run the sendresult script, normally the commands.json would reference a script that would run the sendresult script last, and send back the value of an environment variable like this:

                              ~/.TRIGGERcmdData/sendresult.sh ${RESULT}
                              

                              The one problem with the above method is it uses one of the non-smart home TRIGGERcmd Alexa skills. Those skills are not as reliable at matching the words in the sentence pattern it uses to run the command. The TRIGGERcmd Smart Home Alexa skill does a much better job.

                              TC / TRIGGERcmd / Trigger Command Alexa skill pattern:

                              • Alexa, ask TRIGGERcmd to run Calculator

                              TRIGGERcmd Smart Home Alexa skill pattern:

                              • Alexa, turn on Calculator

                              If you want to use the TRIGGERcmd Smart Home skill to run your command, you use this method.
