Currently, when the device is switched off (intentionally or due to power cut), Tasmota only supports starting with the last known weight (Sensor34 7) or starting with 0 kg. In either case, this is sometimes not the desired functionality. For off-site logging of weights, it is more useful to report the raw, absolute value from the HX711 and to do calibration/tare in upper layers. Note: although it is called "Raw" value, the value is both averaged and scaled! It is just the offset compensation that is missing.
