==> ValueError: could not convert string to float: 'report_telemetry' Still think you're providing more info to weewx than just the one element you want. It's hard to convert "true" to a float.
You need to ignore report_telemetry and measurementID via your weewx.conf, as we gave you numerous examples earlier in this thread.
