siegried,
i had not considered that approach! an mqtt driver that feeds weewx with
data from any mqtt broker would useful for many use cases.
i have seen two general approaches: (1) publish each observation, e.g.,
/telemetry/outside_temperature with data 32.3, or (2) publish a group of
observations as json data, e.g., /telemetry/weather/loop with data
{'outside_temperature': 32.2, 'outside_humidity': 42, 'pressure': 1011.2}
what topic structure does openhab expect?
what other mqtt topic topologies have you seen?
