Re: Alexa Routine to publish MQTT to be picked up by RPi

JFI
Unfortunately, node-red-alexa-local doesn't work with recent Alexa devices :(

The node says it is coming but hasn't been updated for 11 months so may be a legacy project

I'm using

node-red-contrib-alexa-home-skill

Its a bit more involved to setup but has proved quite reliable

If you use VNC to view a Pi over the network - you only need to type in username/password once and it will remember and auto login all subsequent times

Re: 20 rasberry pi zero

The only viable way for such a quantity is (as you've worked out) to make 20 single purchases for the PiZero and PiZeroW

Any UK distributor is allowed to sell you 20 PiZeroWH so that might be an option for you if no-one in USA will do so

Re: is dead 3V3 a widespread issue?

There has been an minor issue with shorting 3v3 to 5v causing the PMIC to die. We've done all that we can to prevent this sort of user error from damaging the board.
Does that mean changes have been made to to the original Pi3B+ design to mitigate this issue?

Is so , what changes have been made?

Re: Defining Gps Area

If you can afford to use another Pi with a camera and you can mount it to look across the area, you can get it to decide whether your car is exceeding its area bounds and send it a signal (i recommend MQTT for this). The hard part is getting the car to be uniquely recognised - you can use colour for...

The best VFM way to use a Pi is to plug in a keyboard,mouse and screen. - fraction of the price of a Pi Top setup If your having to move your a class set around then an integrated solution is more convenient. If your Pi are staying within one school, I'd personally run them headless and VNC into the...
