I have a problem with DS18B20 temp sensors. There are at least 30 of them in my device tree. They all have the same serial number. when I try to remove them, the just keep showing back up! the dash board is becoming unusable because of all the effort to show the sensors.
Things I’ve tried-
1- removing them using cayenne interface- doesn’t work, they come back in 2-3 min
2- reinstalled cayenne- no go, still there.
3- selecting and removing from left pane- no go, return in a few min.
Is there a way to remove devices in a batch? One at a time if frustrating and not effective.
I had this bug last year. Can’t remember what exactly it was but might have been server or Jessie version. I searched posts but nothing yet. That’s a place to start. I have searched several posts but can’t find anything that I posted concerning DS18B20 sensors. resetting dashboard might just work.
Reset from dashboard. No go.
Tribles, I think there are even more now. I afraid to look anymore. This sounds like the last entry in a diary found next to a skeleton…
I have reinstalled cayenne again and no luck , yes the widgets are reading from the same sensor (based on the serial number)
I will install new version of Stretch. I’m new to the Pi/Cayanne world and I was not aware of Stretch. I will install on a card and try it out.
Very odd and glad you found a fix. Please let us know if it recurs at any point. Each DS18B20 should have a unique address, I wonder if they were rotating somehow.
I am not sure if my issue is the same.
My fishtank underwater sensor “ds18b20” also bred like rabbits, it turned out the sensor was broken; replacing new sensor fix the issue.
