Trigger light effect from another pi

    I am attempting to trigger the lights running on a pi from another pi. As an avid hockey fan i created my own version of the goal lights (similar to police light effect). I want the lights to be triggered automatically similar to the Budweiser red light. I have script running on another pi that checks the score and is currently setup to play audio through a speaker attached when my team scores a goal. What i am trying to do now is get this pi to communicate with the lights pi to trigger the light effect with it. I know on the lights pi i need to send


    /storage/hyperion/bin/hyperion-remote.sh -e "Goal" -d "40000"


    My question is how do i send that from the triggering pi?


    I'm assuming i can just hit a web service link as I think thats how the chrome and android apps work.


    Apologies if this is a simple answer, i'm still fairly new to this. Interaction designer by day, tinkerer/Connoisseur of many things by night.

    I think you should install sshpass and then the following command should work:


    sshpass -p 'YourPassword' ssh user@host `/storage/hyperion/bin/hyperion-remote.sh -e "Goal" -d "40000"`


    However I've never used sshpass by myself, so can't guarantee it's ok.


    You can also add --print to your hyperion-remote command and the JSON result sent to the hyperion RPi via TCP should execute the desired effect.


    I'll have to give that a go, thanks!

    could you clarify the -a? I am uncertain how to communicate with the hyperion-remote on the other pi. I know it should be something simple and i feel i am right on the precipice of figuring this all out.


    I think i should have specified that i do not have hyperion remote on the pi, i was referencing the web app, i was hoping to just pull a script from it, but then trying to put pieces together it hit me that you are probably saying i should put hyperion remote on my triggering pi and then the -a is just the ip of my lights pi. So now just to figure out how to get to Hyperion-remote on the trigger pi. Thanks for the insight, i hope i am on the right track. I dont know why i strayed away from the forums for so long.


    The SSHPass psuedo worked, when I ssh into my triggering pi and run the SSHPass command it first opens the connection to the lights pi and then if i run it again will trigger the lights but stays in the lights pi so i dont think that is a viable option. I've run wireshark hoping to track the TCP but its not quite clear what its sending.

    Just copy hyperion binaries to your triggering pi. Call there hyperion-remote -a ip_from_hyperion_pi:19444 -e Goal -d 40000


    I was actually literally just getting down that road. I was struggling to connect directly to the hyperion-remote, (still a newb to this more back-end stuff i was trying to hit hyperion-remote.sh) But alas it worked! Now i just need to edit the triggering script and apply my new data.


    Thank you all for your help!
