Temperature sensor addon for Shelly 1 not working

I had a Sonoff TH10 with a ds18b20 sensor that was included in the device. Everything was working properly. I decide to switch to a Shelly 1 V3 with temperature addon. I make the Shelly connection first. Everything's fine. The problem comes when trying to connect the temperature addon. When stripping the wires from ds18b20 I see that the colors are red, black and white. I connect red to red, black to black, and white to yellow. When I connect the addon to Shelly, it stops working automatically, the IP web is not responding. If I disconnect the addon it works again. If I connect the addon again without the yellow cable, it doesn't work either. If I connect the addon again without the three cables, it does work (only Shelly logically). Does anyone know what can happen? Is the sonoff ds18b20 not compatible? Thanks.

did you take the shelly off the power when connecting the add-on?

Yes, I tried that too but I was unsuccessful
