Cayenne with local scheduler

After updating my raspberry 1 B+ with 2.0 Agent I lost my Schedule, turn relay on at morning, and turn off at midnight. So I made a Python program to control this GPIO and I added to crontab at specific time. After doing this I have rebooted and Schedule Works fine but I lost control from Cayenne Dashboard. I rewind everything to start and problem not solved. So I left the cron Schedule but I want to recover cayenne control.

My py is:
import RPi.GPIO as GPIO

and other same with:

my contrab text is:
0 07 * * * python /home/pi/python/
0 01 * * * python /home/pi/python/

Can somebody tell me what is happening? Please

See if the cayenne service is running service myDevices status and the log tail -f /var/logs/myDevices/cayenne.log

Hi Shramik, I’m not at home but I remember that agent.db has an error, don’t remember which one and:
pam_exec(login:session): conversation failed

and webiopi was not working, I don’t if with this new agent it’s normal or not.
And my dashboard is working well, Online, but just when I want to switch on/off this relay is not working, just with python, if you need more information, just ask, thanks

@jburhenn tagging for this.

@stefschin Yeah, webiopi is no longer needed with the new agent so that is normal.

So just manually switching on/off from the dashboard fails? Can you attempt to switch it on/off and post the /var/logs/myDevices/cayenne.log data from that test? Also, how does the widget behave when you try to switch it on/off? Does it get stuck showing the spinning circles or does it revert to the standard on/off button icon?

Hi J, ok with webiopi, yes, just switching on/off from dashboard same gpio as I use it with python. In app just revert icon until I quit and enter again and stays off, in dashboard show spinning circles and after about 20-30 seconds stay off and nothing happens to GPIO 21

i guess you are familiar with python, so you can try adding a new device to cayenne using GitHub - myDevicesIoT/Cayenne-MQTT-Python: Python Library for Cayenne MQTT API

You mean that I turn this switch on/off with python instead of agent?

If @jburhenn not find anything to do, I will try your advise, thanks

Strange. That log doesn’t seem to show any errors. I’m not sure what the issue would be.

Can you post the output of this command: ls -l /sys/class/gpio/gpio21/?

Also, can you run the commands below, then try to switch the state using Cayenne, then run them again and post the output here?

cat /sys/class/gpio/gpio21/direction
cat /sys/class/gpio/gpio21/value

It works again!!! thanks, I do what you say and when I test switch in cayenne I saw that it was on, I turn gpio off with python and then turn off Cayenne switch, but after that, I turn it on and it works, I don’t know what append.

Thanks @jburhenn

Glad that’s working for you now. If you see the issue again, please let us know.

Yes @jburhenn, I have seen issue again but I find a way to correct it, in GPIO menu from cayenne, GPIO is set to IN, I touch it on my app to change to OUT and it works again! I hope it helps, Cheers

when you add an actuator widget to the integrated GPIO pin it automatically assign that pin as output and LOW/HIGH depending on the state the button is currently.
Can you try adding another button and check the state of GPIO in the menu. Try a refresh of the app if it does not show up.
