This is more of a query to see if others have seen similar behaviour
I have a number of Arduino based devices with ethernet connected at test sites and sharing a connection to the internet
One site has a device with no built in MAC and uses the cayenne generated one - The other site has proper unique MAC’s so i dont think thats the issue. All units have unique ID’s of course
The units on a site all have the same functions attached to them and use a pretty use standard cayenne - i have some additional code handing a few virtual pins in and out
If i only run ONE of the devices on a given dashboard them seem to behave perfectly - the more devices attached to a dashboard the flakier the whole thing becomes to the point where it isnt stable enough to trust
Both sites exhibit the same/similar behaviour where the devices go “offline” but the “uptime” value i have in the dash board keeps incrementing which means they ARE online but stop responding to commands i send to them
Also one site the slide keeps resetting to ZERO randomly which is annoying…
Still having this issue - device goes offline but is still connected at the device end and still sending data which shows up in the dashboard - commands back to device wont work as its “offline”
Restart of device doesnt bring it back online even though serial monitor output of device says its got an ip and is connected and is sending data
Anyone?!?!?!?!’
About to chuck Cayenne as a platform due to inability to get it working stable
Its pretty much just the std code plus a few bits - the device is still sending data and shows as CONNECTED but the dashboard says offline - completely random! Can go for minutes hours or days just fine. A device power cycle MAY OR MAY NOT bring it back online in the dashboard!

Enabling CAYENNE DEBUG isnt showing anything helpful - the output looks identical when its showing in the dash board and when the dash board says its OFFLINE
Well the good (or bad) news is that I don’t see any of the usual suspects for getting an offline message. Generally sleeping or using delays of more than 2 seconds without calling cayenne.run will cause the issue. Can you post all the hardware you are using? I’ll try to match as close as possible and let it run at my house to see if I have any issues. @bestes@rsiegel Maybe someone at Cayenne can do the same?
Yikes @tim2, so sorry for not getting back to you sooner. Are you using a single Arduino w/ multiple auth tokens? Or you are saying you are using multiple Arduinos, each w/ their own auth tokens?
If you have the time can we jump on a Skype call or Google hangouts so I can see the issue in real time and see how your dashboard is configured? You can pick any time on my calendar here Calendly - Benny Estes
I was having weird issues like this until some days ago. I was restarting my RPi every night and notice that was common to have problems after boots, so I stopped the restart procedure and Cayenne just started to work smoothly. Can be only a coincidence, I’m only at third test day by now.
Sorry, that’s a bit over my budget for the “let’s just pick that up because it looks cool” column. I can still try to connect up a few Arduino’s to see if I have issues.
Hi @bestes - not sure how we are going to coordinate you looking at this as its random! All I can tell you is that even when the dashboard says a device is offline the output of cayenne debug looks correct with the flow of messages continuing and the device indicating its online. SO frustrating!
I’m curious if the next time you see a false ‘Offline’ state, if you could load the account in a different browser and let me know if that browser also sees the incorrect Offline state.
Generally all browsers show the same offline devices at the same time – im waiting for the device that is connected to the debug computer atm the moment to go offline
