Hi there.
Did you connect to the GPIO pin and the GROUND pin, or the 3V3 pin, as this may
have caused the issue.
As far as I'm aware, the hardware on the RPI hasn't changed as far as GPIO goes.
Many thanks, Daniel.

Hi, it was the hardware connected to the rpi which means when the gpio is on
the relay is off, therefore rather than have a higher level logic to say if I
want the relay on then switch off the gpio I allowed the config of the meaning
of the on and off in the gpio driver.
The concept is the hardware will be fixed and depending on the electronics
connected to the pi on and off will be different.
I get the argument for not doing this and the app should know what the logic
is, but that just leads to confusion, i prefer to get the hardware and software
in sync, a on mean the relay or whatever is connected to the gpio is on not
that the signal from the gpio is on
Therefore there is no problem i just added more features to the software
Hope this makes sense?
