Hi Gary,
thanks for your advice. After the modification of weewx.conf mqtt data is
still delivered (so tha's positive), but no change in the number of decimal
places.
My config:
#########################
[[MQTT]]
enable = true
unit_system = METRICWX
# Hostname/IP of MQTT broker
host = 192.168.2.22
topic = weather
# append_units_label = false
[[[inputs]]]
[[[[outTemp]]]]
format = %.2f # use two decimal places of
precision
name = outside_temperature # use label other than inTemp
[[[[windSpeed]]]]
units = meter_per_second
format = %.1f
name = windSpeed_m_s
[[[[windGust]]]]
units = meter_per_second
format = %.1f
name = gust_m_s
###########################
and the result in the broker:
###########################

Something goes wrong, but I've no idea
