All relay switch automatically turning on when reboot raspberry pi

[bestes]

Hi @faysal1ly,

Welcome to the Cayenne community! I believe this post should help to resolve the issue you are having. You can specify what the RPI should do w/ the GPIO upon Reboot:

GPIO high after boot

I had the same problem with the relays on my pi. To set the GPIO pin to HIGH, these are the steps I took for my GPIO pin number 25. sudo nano /etc/webiopi/config Find the section on [GPIO] and add a new line like this: 25 = OUT 1 Find the section on [~GPIO] and add the same line: 25 = OUT 1 Exit and Save Reboot. The GPIO pin should stay HIGH when rebooting is done. I hope this helps.
