Does anyone else have issues with accuracy/consistency of DS18B20 sensors?

I have two D1 Mini’s, running Tamota, with DS18B20 temperature sensors. I have both of them right next to a Sonoff (far enough away to be influencesd with any radiated heat from the Sonoff), running Tasmota, with a BME280 sensor and there is a substantial difference in readings between them. Currently they are:

DS18B20 sensor 1: 24.2
DS18B20 sensor 1: 23.7
BME280: 21.2

I know that I can set a float in HA to bring them inline, but the DS18B20 do not seem to be consistent in that I have adjusted the float several times but after some time them are misaligned again.

I believe that the DS18B20 can have different resolutions, using 9 up to 12 bits, but I have no idea of what Tamota runs at as default, or whether it can be changed, but even at 9 bits I would expect them to have a more consistent temperature.
