I got the microwave radar modules today!
They work great, even behind my mirror, although they are very sensitive. It triggered on even small arm movements and didn’t require line of sight. Works for my needs though, I just want it to turn off the monitor when nobody is around.
I haven’t tried powering them with my PI, but they worked fine with an external 5v power supply.
@yawns I’ve read that microwave sensors will work behind glass, but I’m not sure if it will work behind the semi-mirrored surfaces we’re using.
Hmm I’ve seen othe specs that say working voltage is 3.3-20VDC… hopefully that’s more accurate. In any case I’ll try it with the 5V from the PI and go from there.
Another possibility: I ordered a couple of these $2 microwave radar motion detectors to see if they will work behind my glass. Still waiting to receive them though:

Ditto. Anyone have luck with this module using the picam?
@gndimitro Ah! Heroku needs to tell your app which port to run on. An update to config.js to take the environment’s PORT value into account may do the trick:
port: process.env.PORT || 8080,
Oh actually read to the end of your post :) Looks like the music module runs the player on the server side (on the heroku dyno) which is what’s likely failing. You can run heroku logs -a <your appname> to see any error messages.
I imagine it should work since it’s a node app. I haven’t tried it myself but creating a procfile that runs node serveronly may be enough:

Wow that looks great! Particularly the weather forecast.
I looked at creating a graph since the data is all right there in the response. I might as well see I can port the code over to this module!
