wpi2 at bootstrap

[kiondi]

Hi
Thank you for your great job.
I have a problem when raspberry boot.
My relay board, connected on gpio (active with LOW signal) switch from HIGH to LOW all time raspberry start.
How can I do to not blink the outputs at each reboot?
thank you for any suggest.

Does it flash when the Pi boots, or when homebridge starts?

Not sure it's possible to control the pin states until after the Pi has booted - because they haven't been initialised by the kernel. That would mean you would need to design a circuit that handles the reboots electronically rather than software.

If they don't flash during the actual boot, and only start misbehaving during homebridge startup, then there probably is something we can fix in the plugin.

The gpio start HIGH (one time for a few milliseconds) during homebridge startup.
I try to unistall the plugin, for test, homebridge start without blink on relays board.
Thank you for the support.

I /think/ the fix may be to set the value before the direction - which happens inlib/autoExport.js

It would need the line

     gpiopin.value = (!inverted);

... moving in between the .export command and .direction.

I'm not near my Pi setup at the moment to give it a try - but if you're able to test that as a fix, that would be great. Got a bunch of other changes to publish as well, so can work this into the next release.

I move command line between the export and direction but is the same at homebridgestrat, the code:

Ok - thanks for trying. Will do some more testing when I've got time in front of my Pi.

Ok, I leave you a video of the stratup sequence with 2 relays connected on gpio.
Best regards

Struggling with the same.. have you managed to solve it? It opens my garage on rpi startup :D
