john, it is not unusual for the acurite console to lose contact with the sensor cluster. when this happens you will see the log messages about 'ignoring stale data'. the console still reports values for the sensors (and i think the console still shows values for the sensors), but those values cannot be trusted, because the console is not communicating with the sensors. when this happens, weewx reports a 'None' value for each observation (exactly which observations are reported depends on the type of packet - R1-type1, R1-type8, or R2).
you can plot the rssi value over time - it is mapped to the weewx schema as rxCheckPercent. the console reports a value of 0, 1, 2, or 3, and that is mapped to a scale of 0-100. if you see consistent signal loss, you might try improving your signal reception using the usual techniques (move the console closer to the cluster but not too close, eliminate all forms of interference, hack a high-gain antenna, build an amplifier, etc). when you see 'ignoring stale data' in the weewx logs, make a note of what you see for reception on the console (the vertical bars) and sensor values. that should give you some idea about whether/when the console is lying to you. you can also correlate the 'ignoring stale data' messages with the None/NULL values at weather underground. do this by analyzing the log and/or with the weewx database values for outTemp, rxCheckPercent, etc. i would be surprised if there is no correlation. m -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
