If it just happens time to time then it's likely just a bad connection somewhere, too long wires or incorrect resistance.
You can filter out NAN values using the filter_out

I've tried yet another power source - this time my main phone charger and all the issues were gone. It looks like, a cheap phone chargers aren't good enough.
Operating environment/Installation (Hass.io/Docker/pip/etc.):

I have two one wire DS18b20 sensors connected to the same pin. From time to time one of them returns NaN and in logs there is "Scratch pad checksum invalid!" but I have no idea what to do about it. I power my devkit from random usb charger, and sensors from ESP.

I've tried diffrent power source and reconnecting components.
