" Please fix the following errors:
Hello when I try to enter a relay on channel 4 I have this error return, it’s the only channel that gives that the others work correctly could you tell me why
It’s a raspberry pi 2 and a shield : KS0212 keyestudio RPI 4-channel Relay Shield - Keyestudio Wiki
thank you for your help (I go through a translator sorry for the mistakes I am French)
that is because GPIO4 is 1 wire port and cannot be used as general GPIO port.
But it’s à shield i dont move the pin it’t locked…sorry for m’y english…
are you familer with python? you can use GitHub - myDevicesIoT/Cayenne-MQTT-Python: Python Library for Cayenne MQTT API to control the relay manually.
I will try, I am also testing yana server in parallel in all thanks for the help

Hi shramik,
Having same problem here, as cayenne see that port as data.
As far as i can see it is gpio as any other.
Complete noob here 
Is there a way to change that
I am talking about port 4, pin7
yes, it is a GPIO but it is used as 1 wire pin in cayenne agent. So you cannot use it as general purpose pin.
No way to change that?,
i found the way to change it in raspbian.
Thats bad
