The rtl_433 utility is able to listen for and decode specific 433 MHz radio transmission messages using a RTL-SDR USB dongle. It supports sending decoded messages to various destinations including MQTT. As a result, we can use rtl_433 to effectively act as a gateway between 433 MHz radio transmissions and our Home Assistant MQTT broker.

	For my personal setup, I have a Nooelec RTL-SDR USB dongle plugged into a OpenWRT router. The rtl_433 package is available on OpenWRT 24's package repos. ~~Once installed~~, run the following ~~to listen for the Govee messages~~:		For my personal setup, I have a Nooelec RTL-SDR USB dongle plugged into a OpenWRT router. The rtl_433 package is available on OpenWRT 24's package repos. You can create a procd init script that runs rtl_433 within OpenWRT by creating a file in /etc/init.d/rtl_433 with the following contents:

			{{Highlight
			\| code = #!/bin/sh /etc/rc.common
			USE_PROCD=1
			START=95
			STOP=01

			start_service() {
			procd_open_instance
			procd_set_param command /usr/bin/rtl_433 -C si -R 231 -F "mqtt://mqtt-broker-server:1883,devices=rtl_433/Govee-Water[/id]"
			procd_close_instance
			}
			\| lang = text
			}}

			If you are not using OpenWRT or if you want to run the command manually, run the following:
	{{Highlight		{{Highlight
	\| code = # rtl_433 -C si -F mqtt://mqtt-broker-server:1883,devices=rtl_433/Govee-Water[/id]		\| code = # rtl_433 -C si -R 231 -F mqtt://mqtt-broker-server:1883,devices=rtl_433/Govee-Water[/id]
	\| lang = terminal		\| lang = terminal
	}}		}}
	~~The~~ MQTT topic ~~specified here is~~ <code>rtl_433/Govee-Water/<device-id></code>.		Breaking the command down, the arguments are as follows:

			* <code>-C si</code>: Convert units to scientific units
			* <code>-R 231</code>: Decode only Govee H5054 messages. You can list all the supported messages by passing -R help.
			* <code>-F</code> specifies the output. In our case, we want to use MQTT without authentication using the topic <code>rtl_433/Govee-Water/<device-id></code>. rtl_433 will replace <code>[/id]</code> with the actual device id.

	To get Home Assistant configured for these sensors~~, add~~ the MQTT integration.		Once rtl_433 is running, we will need to get Home Assistant configured for these sensors. Add the MQTT integration in Home Assistant.

	Next, use the auto-discovery script at: https://github.com/mekaneck/Govee-Water-Leak-Home-Assistant-Autodiscovery. The installation involves copying and pasting the script into the Home Assistant configuration file. The script contains a list of devices that should be added. You will need to determine the random 5 digit device ID that the sensors are set to from the factory, their serial number (optional but helpful for you to identify the sensors later on), and a friendly name. Save the configuration file, restart Home Assistant, and then run the script (under Settings -> Automation -> Scripts). After running the script, you should see the sensors appear under the MQTT integration.
