No dashboard update after reboot

Community Help With My Project
1

I have returned to Cayenne after some time on other projects and taken my Raspberry pi back to a fresh install of both rasbian and Cayenne. I have create a few generic digital switch and temperature.

On first creation, the dashboard operates as expected with changes in switch state displayed immediately - so all seems to be working. However after a reboot the dashboard seems only to show data up to the point of reboot (ie is fixed) and nothing after. I have to delete the raspberry pi device and re- add and then configure the switches etc to get it to work. I have reserved an ip address on my router for the raspberry pi but this had no effect.

What am I not doing?

  • Pi Model B+ (Rasbian) Agent 2.0.4.280
  • Web Dashboard

check the logs tail -f /var/log/myDevices/cayenne.log for what error it is pointing out.

can you try following command.

sudo service myDevices restart
tail -f /var/log/myDevices/cayenne.log

and share the logs

The service restart seems to reestablish the connection:

try running groups cayenne to see what groups the cayenne user belongs to

7

pi@raspberrypi : ~ $ groups cayenne

cayenne : cayenne spi i2c gpio

8

can you check groups gpio

9

pi@raspberrypi : ~ $ groups gpio

groups: ‘gpio’: no such user

pi@raspberrypi : ~ $

10

@shramik_salgaonkar Any thoughts?

11

everything seems fine. Not sure what is the issue. Only option is to restart cayenne agent manually.

12

could I run a cron job to restart the service after a reboot ?

13

yes, you can give it a try.
