I’m following the following project (and still new to HA)
https://community.home-assistant.io/t/balboa-hot-tub-spa-automation-and-power-savings/353032?page=3
I’ve set up the HA side with Mosquito MQTT and installed Ruby and the below gem on the raspberry pi that will sit Hot tub side and is hardwired to the hot tub (as described above). When it comes to the MQTT bridge (hot tub side) I’m a bit stuck with how to modify the MQTT bridge.service file (described below)
https://github.com/ccutrer/balboa_worldwide_app#mqtthomie-bridge
the instructions state to “modify the file to pass the correct URI to your MQTT server, and path to RS-485 device or hostname/IP for WiFi”
The .service file currently looks like:
[Unit]
Description=Balboa Spa MQTT Bridge
[Service]
User=cody
ExecStart=/usr/local/bin/bwa_mqtt_bridge mqtt://localhost/ /dev/ttyUSB0
Environment="LOG_LEVEL=WARN" "LOG_VERBOSITY=0"
Restart=always
RestartSec=3s
Type=notify
NotifyAccess=main
WatchdogSec=60
[Install]
WantedBy=multi-user.target
I have already changed the dev/ttyUSB0 which is the RS485 connection - but not sure what else to change on that line to provide the other URI details. is local host enough without further change? In addition, does USER need to be the user associated to the Mosquito MQTT server in HA ?
Thanks in helping me get this over the line!
