RTL_433 MQTT help

HA’s MQTT integration is installed and seems to be operational. I’m trying to send a LaCrosse-TX141THBv2 sensor’s data to my HA. I’ve gotten this far:

rtl_433 -R 73 -C customary -F mqtt://homeass:1883,user=mqttu,pass=mqttu


rtl_433 version 21.12 (2021-12-14) inputs file rtl_tcp RTL-SDR SoapySDR

Use -h for usage help and see https://triq.org/ for documentation.Trying conf file at “rtl_433.conf”…
