    I tried to add my Motion Sensor which is HC-SR501 and connect it exactly like the official guide on Cayenne Docs, but everytime i do that i get this error Failed to add the sensor (Device command failed), i tried to use another GPIO pin and same problem occurs, also everytime i tried to enable I2C from myDevices Web then my Raspberry Pi will not show online on the website even though im writing this from my Raspberry Pi.

when executing the command: service myDevice status i get

I tried to format the SD card then made another image but same problem occurs when i add motion sensor

2

can you run this command tail -f /var/log/myDevices/cayenne.log and while it is logging, add the motion sensor.

3

Same problem occurs, here’s the log

cayenne.log (620.8 KB)

4

the log shows that there are already digital Motion sensors added. are you adding one more on same channel?

5

Actually, when i saw the dashboard there was a lot of widgets add on widgets and i deleted those because it wasn’t interacting with my Motion sensor

6

can you delete the devices and re-add a new one. Add a motion sensor and share the log if an error occurs.

7

The problem is when i delete those and want to add my Motion sensor from add devices i get the same error, and when i go back to the dashboard i see 8 add on devices which i never added them and they are greened out

i said delete device not widget.

9

Sorry i am new to this type of environment, i’m gussing you mean delete the device on the left panel correct?
if so then i did delete from there

10

to delete the device, you need to open the device setting by pressing the clog wheel icon on top right of the device dashboard,

Oh, i get it now, i tried it now, and my sensor got working finally.

Thanks
