482 +When connecting to current sensors sold by our company, you can convert current readings to corresponding values by simply configuring the [[AT+PROBE>>||anchor="H3.3.4SettheProbeModel"]] command. If you prefer not to configure this command on the sensor, you can uniformly handle the conversion in the payload decoder instead.
