Weird widgets on dashboard


When trying to connect DS18B20 temperature sensor to Cayenne dashboard using raspberry pi 3.
The slave address is not detected.
Instead, some weird widgets are populated on the dashboard. Kindly explain how to get rid of it and get temperature on dashboard using ds18b20.

Connections of ds18b20 to pi 3:
DS18b20 +ve = Pi 3 (3.3V pin)
DS18b20 -ve pin = Pi 3 (gnd)
DS18b20 data pin = Pi 3 (GPIO4) I wire pin



I just now added a DS18B20 and it got detected. you need to add a pull-up resistor between data and vcc. when you turn on pi after the connection, it should automatically add the temperature widget to the dashboard.
