Hi,
maybe I can understand something but after installation Cayenne I dont see my gpio in dashboard
I turn gpio remote control in raspi-config, but nothing happens
Please help with this problem
Hi @hypnojesus, welcome to the Cayenne Community!
Could you post your output from the command uname -a ? I think this could be because you are running a Linux kernel on the pi newer than 4.4. Currently we support what is in Raspbian Jessie and Jessie Lite, the 4.4 kernel, and are aware of issues with the 4.9 kernel.

You actually rigth,
Linux raspberrypi 4.9.16-v7+ #978 SMP Sat Mar 18 13:59:01 GMT 2017 armv7l GNU/Linux
I just downgrade kernel on 4.4.50 and you now my problem completely solved
Thank you so much

Hi, I have the same issue (no GPIO dashboard, itās empty):
root@raspholepi:~# uname -a
Linux raspholepi 3.6.11+ #474 PREEMPT Thu Jun 13 17:14:42 BST 2013 armv6l GNU/Linux
PS) I donāt understand in the previous description by hypnojesus āI turn gpio remote control in raspi-configā ā¦ I donāt see any option to enable it.
Thanks in advance.
Hi thanks,
I understood I donāt have this menu on my version but I installed it and itās running (netstat -lnput):
tcp 0 0 0.0.0.0:8888 0.0.0.0:* LISTEN 4192/pigpiod
ā¦ but unlikely the GPIO dashboard is empty.
Is there any command to debug my situation?
Thanks in advance.

This looks to me like you might have the opposite version ā a very old kernel? Iām used to seeing the 4.4 Linux kernel on Piās running Raspbian Jessie. Could you run:
cat /etc/os-release
to see what version of Raspbian youāre running? The Cayenne Pi Agent currently supports Raspbian Jessie and Jessie Lite, though if youāre tied to some other OS, perhaps the Cayenne Linux Agent or a Python MQTT Client would be other options to explore for connecting your device to Cayenne.
I have this same problem. I canāt seem to do anything related to GPIO.
If I create a Generic Device on GPIO 17 (pin 11), yet it doesnāt show up on the left side when created.
pi@RPI-Generator:~ $ uname -a

This is a clean build. Am I missing something obvious, or is this a bug or limitation?
The Icon is created, but is missing on the left side, so you canāt drag anything in to create a trigger. Also, when you look at the GPIO page, you donāt see that port as an input or output.

Hi Rsiegel,
I have an older version (Raspbian GNU/Linux 7 (wheezy)), Iāve tried with another SD card with Jessie onboard and I confirm it works.
Iāll check if Cayenne Linux Agent can work on my Wheezy version as suggested.
Thanks for the support.

Hi @mike7 and welcome to the Cayenne Community.
The issue is that webiopi, a component of the Cayenne Pi software, is not yet compatible with the 4.9 Linux Kernel. There are a few options to resolve this until we push an update with support for this kernel:
If you have no specific need for the 4.9 kernel on your Pi (most people would not), you can downgrade to 4.4 by running this command (it will require a reboot after it runs)
sudo rpi-update 52241088c1da59a359110d39c1875cda56496764
After youāre running 4.4 again the problems youāve described should automatically go away.
If you do need the 4.9 kernel or donāt want to downgrade, you can try a beta of the new agent weāre testing resolve this issue, and a number of others. Just be aware this is beta software and you may encounter bugs (please let us know if you go this route, and do have trouble)
To try it out:
First get the test agent install script:
wget http://updates.mydevices.com/raspberry/rpi_testing.sh
If updating an existing install run:
sudo bash rpi_testing.sh -update
If this is a new install get the invite code from adding a new Raspberry Pi via the Cayenne Dashboard. The invite code is part of the install file name listed in the Terminal/SSH instructions: rpi_[invitecode].sh.
Run the rpi_testing.sh script with this invite code:
sudo bash rpi_testing.sh -code [invite code]
Thanks
I downgraded the firmware and that solved it. I should have asked about 4 hours earlier.

Glad it worked. Sorry for the trouble, itās a bit of a frustrating one if you donāt know what youāre looking for.
Hi,
Thanks for sharing the test agent script. I tried it with Linux Kernel 4.9 and I confirm that I can control the GPIO pins from the web interface on my laptop. However, the pins still cannot be controlled through the Cayenne app on my iphone. Is there a way to make this work as well?
All the best,
David
@rsiegel can confirm, but Iām pretty sure the test agent uses MQTT for communication which means the iPhone and Android apps will not work correctly until the test agent is officially pushed out.
@salekd @mike7 @gianluca.torriglia @tiendle @hypnojesus We have just released an updated Cayenne Pi agent version that includes the fix for 4.9 Linux kernel. It can be downloaded by installing a new Raspberry Pi through the Cayenne add device process.
We will be updating all existing Pi agents w/ this fix very soon, so you may prefer to wait until we roll out the fix. Either way, Iām hoping that you will be able to confirm our fix is working

Just bumping one more time to note that the existing agent auto-update has been released as well. Itās totally a silent update, so there would not be any indication on the user side. Feel free to use rpi-update to move forward to the 4.9 kernel at this point if youād like!
@salekd Iād be interested to hear if this new agent is allowing you to manipulate the pins via the iOS app, and if not, if you could share a bit more information on what exactly youāre trying to do in the app that isnāt working.
Thanks for mentioning rpi-update, I used it to move from kernel 4.9.35 to 4.9.54 which, as I understand, includes the new Cayenne Pi agent. However, I still cannot control the pins through the GPIO section of the iPhone Cayenne app.
I have also defined a button in the dashboard, connected to one of the output GPIO pins. I can switch this button on and off from my iPhone (I was not able to do even this before), but nothing happens in reality. From this I conclude that the new firmware still does not fix the problem. Or did I miss any important step in the firmware update?
Cheers,
David
Hi @salekd,
Basically our new agent version should have come down the pipe automatically. The goal was to fix an incompatibility with the 4.9.x Linux kernel in general. You can check if you have the newest update with the command curl http://127.0.0.1:8000/version. The old version is 0.7.22, new one is 0.7.23.
That being said, Iām not aware of any incompatibilities between different sub-versions of 4.9. After seeing your post, I tested with 4.9.41 and 4.9.56 (just what my Pi was on, and what rpi-update updated it to without demanding something specific), and in both cases I was able to control a LED with both the GPIO tab, and a button widget, with both iOS and web browser Cayenne.
If you do have that newest agent version, the next thing Iād test is if youāre able to turn on and off the pin outside the context of Cayenne, with something like a Python script. Let me know if you need help finding one to do this. It would also be a good sanity check of your wiring to make sure thatās not the issue here. Might be worth trying on a different pin as there are a few that have reserved uses that could be causing an issue as well (which pin are you having trouble with?)
Hi @rsiegel,
Thanks for testing this. As I said previously, controlling GPIO pins through Cayenne in a web browser on my laptop works for me. It is only the iPhone app that doesnāt work. Following your suggestion, I tried testing the version by doing curl http://127.0.0.1:8000/version on my Raspberry Pi Zero and I got the following error:
curl: (7) Failed to connect to 127.0.0.1 port 8000: Connection refused
Can this be part of the problem?
Cheers,
David
