Here is a documented list of all of the various MQTT topics and their purposes / values.

/rv/heartbeat

This is pinged by the RV HomeAssistant machine every minute, useful for monitoring connectivity in the real home's HomeAssistant

/rv/gps

The GPS location of the RV as provided by the GPS subsystem (RPi Zero W with a GPS / 2G modem attached)

{
  "latitude" : 123.45,
  "longitude" : 123.45,
  "speed" : 123.45,
  "sat_found" : 15,
  "sat used" : 10,
  "gps_accuracy" : 5
 }

All ceiling LED lighting uses the HomeAssistant JSON schema for setting light values.

For each base state topic /rv/lights/bedroom there is a corresponding /rv/lights/bedroom/set to change the state.

/rv/lights/bedroom

/rv/lights/kitchen-sink

/rv/lights/kitchen-walkway

/rv/lights/kitchen-stove-1

/rv/lights/kitchen-stove-2

/rv/lights/bathroom

/rv/lights/livingroom-1

/rv/lights/livingroom-2

/rv/lights/office

/rv/lights/bar

/rv/sensors/motion/1 - Publishes detected if motion was detected

/rv/sensors/tanks/fresh

/rv/sensors/tank/grey

/rv/sensors/tank/black

{
  tank : 'fresh'
  percent_full: 25
}

/rv/sensors/water-pressure

{
  psi : 41.1
}

These are boolean sensors that indicate if a given circuit has AC power in order to determine what kind of AC power is available to the rig. Each topic pushes a { powered : true } when AC power is detected.

/rv/sensors/power/50A1 - The 50A AC power sensor

/rv/sensors/power/50A2 - The 50A AC power sensor

/rv/sensors/power/30A - The 30A AC power sensor

/rv/sensors/power/generator - The Generator AC Power sensor

Monitors the temperature and relative humidity at various locations in the rig.

/rv/sensors/temp-rh/cabin - Temp/Humidity inside of main cabin /rv/sensors/temp-rh/bathroom - Temp/Humidity inside of bathroom /rv/sensors/temp-rh/water - Temp/Humidity inside of water storage /rv/sensors/temp-rh/outdoors - Temp/Humidity outdoors

Publishes the charge data for the LiFeBlue 100AH LiFePo4 house batteries. The <address> is the device address from Bluetooth. Requires an ESP32 running This Smart House LifeBlue-BLE Firmware

/rv/sensors/batteries/<address>

{
	battery_id : '<address>', // Bluetooth Address
	voltage : 13.2, // Voltage of Battery
	current : 4000, // current in mA drawing from battery
	ampHrs : 100000, // mAhs of charge remaining
	soc : 95, // State of Charge (%)
 	temp : 23, // Temp of battery in C
 	status : 1234, // Bitmask of status
 	afeStatus : 1234, // afeStatus bitmask
 	cells : [ 1, 2, 3, 4], // Individual cell voltages
 	cycles : 10, // Charge cycles of battery
	status: {
		cell_high_voltage : false,
		cell_low_voltage: false,
		over_current_when_charge : false,
		over_current_when_discharge : false,
		low_temp_when_charge : false,
		low_temp_when_discharge : false,
		high_temp_when_charge : false,
		high_temp_when_discharge: false,
		short_circuited : false
	}
}		

/rv/input/keypad/[keypad num] - Publishes which key was pressed on keypad, or H<key> if key was held down
