Plus Uni cannot find ds20b18 Temperature Sensor

[Peter2601]

Hi there!

I have tried to connect a temperatur sensor ds18b20 to new Plus Uni. The Plus uni has recent firmware 1.3.3.

I connect the Sensor as described in the manual to Sensor VCC, Data an ground, as in manual desribed. After that I tried to add peripheral in the shelly GUI. Unfortunately the sensor cannot be found by the shelly. The error message is "Temperature DS18B20 peripherals not found." 

I tried also another sensor and another Plus Uni, the result is always the same. - Has anybody an idea what could be wrong?

BTW: some time ago I added succsessfully up to five ds18b20 to a shelly plus addon on an Shelly Plus 1 - I never hab a problem with one of the sensors...

I can't reproduce any problem here with DS18B20 and Plus Uni with 1.3.3. Please show your cabling again exactly (photo)

I have already fixed the issue: It seems, that I had two broklen sensors. - They were new, but they did not work nevertheless. 
When I tried the third sensor, it worked properly.

I believe there's a lot of junk out there in terms of sensors. I've also come across a lot of broken ones.
