Alex - it is unfortunate you're unfulfilled and still unhappy.
I did a test here on a pip installation and it 'does' work for me with mqtt
0.24 in setting both more and fewer numbers to the right of the decimal
point.
I added an input setting things to 5 digits and restarted weewx....
[[MQTT]]
client_id = ecowitt
server_url = mqtt://192.168.1.171:1883/
topic = ecowitt
log_success = false
log_failure = true
enable = true
[[[inputs]]]
[[[[outTemp]]]]
name = outtemp5
format = %.5f
unit = degree_F
pi@pi4:~/weewx-data$ mosquitto_sub -t ecowitt/outtemp5 -h 192.168.1.171
76.10000
I then changed it to outtemp0 and %.0f and restarted weewx again...
[[MQTT]]
client_id = ecowitt
server_url = mqtt://192.168.1.171:1883/
topic = ecowitt
log_failure = true
enable = true
[[[inputs]]]
[[[[outTemp]]]]
name = outtemp0
format = %.0f
unit = degree_F
pi@pi4:~/weewx-data$ mosquitto_sub -t ecowitt/outtemp0 -h 192.168.1.171
76
