Scratch pad checksum invalid, dallas temp sensor at BK7231N
I cant read temperature from onewire dallas temp sensor. It is recognized correctly but every read returns "dallas_temp.sensor set Warning flag: scratch pad checksum invalid". I first thought the sensor was a cheap fake of origin, but same worked with the original firmware from Tuya. In the meantime I tried same sensor on esp8266 and it worked seamless. Please let me know what I might adjust.
