Hi all
First I’m not write good English or code expert 
I have little project where is
1 → Raspberry pi 3 (control arduino and it’s connected lan) and there is Jessie OS
1 → Arduino Uno (control my sensor etc… connected to Rpi3 with usb-cable)
1 → USB hub (connected Uno and Rpi3)
6 → d18s20 temp sensors
2 → Relays (control water pump and fan)
4 → Moisture sensors
2 → water level sensors
Relays, water level sensors and moisture sensors are controlled by Cayenne dashboard. Only code what I have done is temperature sensor code and uptime (see below). Problem is that Cayenne dashboard freezing (after about 1- 10min) when I run cayenne-ser.sh script. Also arduino are freezing and last online status continue running without no control. I have change usb-cables, internet connections, reinstalled Rpi3, arduino codes… etc… I can’t trust that everything works well when I leave my greenhouse. I can do arduino code where everything this works (without cayenne and everything this) but this cayenne dashboard etc… is so good 
mobile control etc… I like
if I add more code to my arduino, cayenne dashboard goes online but freeze immediately. If I run only temp sensors code all works fine. Same situation is all other sensors if I run sensors one by one. Everything works fine if I run one by one but if I add evrything in the same code dashboard will freeze. Maybe Uno can’t handle so many sensors but if look forum there is much more difficult system and one arduino 
I don’t understand what is wrong. Sorry this code are not full english but I think you can handle that.
