I have two DS18B20 connected to an nodemcu on pin d6. They have a pull up resistor across data and VIC of 4k7. Nodemcu is running tasmota. I am able to see both sensor temps but temp-1 has continuous temp errors. It will show the current temp then shows 85c, then back to the correct temp. This shows on the tasmota main menu as well as through mqtt and node red. I created a 5 and 12 hour chart which showed temp-1 fluctuating constantly.
