What’s in the box?
RV Monitor System (RVM1)
The RV Monitor System includes one RV Monitor Station which is a small computer with software (black box in picture on left), USB power adapter and cable, as well as one BTH1 sensor and one BMRV1 sensor. The RV Monitor Station is mounted with provided hook and loop fasteners to a surface inside the RV.
Temperature & Humidity Sensor (BTH1)
Each Bluetooth Temperature & Humidity Sensor (BTH1) operates on a common coin cell battery (CR2032) for about one year. The sensor is attached to a surface with a hook and loop fastener. Battery and hook and loop fastener are included. Up to 10 BTH1 sensors can be added to a single RV Whisper® Monitor System.
Battery Voltage & Temperature Sensor (BMRV1)
A wireless sensor known as the Battery Mole RV (BMRV1) measures Battery Voltage and Temperature. Each BMRV1 sensor is labeled with a unique RV Whisper® serial number. Up to 10 BMRV1 sensors can be added to a single RV Whisper® Monitor System.
NEW SENSOR – DC Power Monitor
View historical data to learn about your RV
RV Whisper® can collect temperature, humidity, and battery voltage data from wireless sensors. All data are stored in a built-in local database, so you can view your RV Whisper™ data on a smartphone, tablet, or computer either locally (in or near the RV) or over the internet. Graph your data against time to track trends in your 12V batteries or fridge/freezer performance (smartphone/tablet/computer not included).
Why do I need RV Whisper®?
RV Interior Temperature Alerts
When your pets have to stay behind in your RV, know if they are safe from dangerous summer time heat. If the RV interior temperature rises above a user-specified threshold, RV Whisper® sends text and email messages to alert RV owners.
Historical Temperature Data
Use a browser on any computer or smart phone to remotely view the RV’s current and historical interior temperature (with user-provided WiFi). RV Whisper® software will graph your RV’s temperature over the last few hours, days, or weeks, so you can know how the temperature has fluctuated over time.
Refrigerator and Freezer Temperature Alerting
Food refrigeration in RVs can be challenging. Propane / Electric fridges are very popular in RVs, but they can struggle to keep food at safe temperatures in hot weather.
With RV Whisper®, you will know if your fridge is staying cold enough! If the refrigerator or freezer temperatures remain above a certain temperature for too long, alerts can be sent to warn you.
Historical data can help you understand why your RV freezer might become warm on occasion – for example, due to regular defrost cycles.
This tool is a favorite among seasonal campers who leave their RV at their favorite RV park for the season. When you are away from the RV for several days, or weeks, it is important to know that the fridge has been keeping your refrigerated items at safe temperatures the whole time you were away.
Even if shore power goes out and your fridge switches to propane, RV Whisper® can continue to monitor the fridge temperature when powered from your RV battery bank. If solar panels are used to maintain the RV batteries at the proper voltage, the monitoring and alerting can continue indefinitely, especially if your RV internet access is a MiFi type system powered by the same solar charged battery bank.
RV Battery Monitoring
Monitor and Log Battery Bank Voltage and Temperature
Monitor your 12V battery banks with wireless sensors that connect to your RV batteries, monitoring the battery voltage and temperature.
Customize alerts to warn you of problems with your battery system. Graph your battery bank’s voltage data over the last few days, weeks, or months to gain insight into how well your energy battery banks, charging system, generator, and/or solar panels are working together to make your RVing experience more enjoyable.
If your RV batteries are kept charged with solar and/or shore power while in storage, then you can have a continuous record of your battery voltage and interior temperature. And if you have internet access in the RV, you can remotely access the data in the RV Monitor System installed on the RV and receive email and text message alerts.
Voltage Logging for RV Technicians
If you have problems with your RV battery bank, the logged data from the RV Whisper® Battery Voltage Sensors can provide valuable troubleshooting data to yourself and/or your RV Technician.
Displaying a graph of your RV batteries’ voltage over the previous few weeks can help an RV Technician, or an RVer familiar with their RV’s 12V systems, quickly determine the root cause of battery issues.
Receive Text and Email Alerts
Set text message and/or email alerts for when temperatures get too hot or voltages are out of range. Text and email alerts are highly customizable for a range of settings, including temperature, humidity, and battery voltage.
Safest When Powered by USB 12V Adapter
RV Whisper® is best powered by a USB power adapter connected to your 12V battery bank; this will provide continuous operation, even when shore power is not available. This is important because if you lose shore power on a hot summer day and you don’t have a working generator auto start system, a shore-powered monitoring system would not be available to alert you of high temperatures due to shore power outage.
It is highly recommended that both your RV Whisper® Monitor Station and your Internet Access (MiFi or jetpack device) are both operated from a USB power adapter that is powered by your RV battery bank.
“Shore Power Lost” Alerts
If shore power is lost and the generator doesn’t start, the RV battery voltage will drop right way to under 13.2 Volts. The Battery Voltage sensor will detect this and an Alert can be configured to detect when shore power is lost. A “lost shore power” alert can be a much needed early warning that RV interior temperatures are likely to be going up soon since the Air Conditioner won’t run without shore power or generator power.
RV Whisper® has many features designed to bring you peace of mind in your RV:
- Track your RV’s indoor temperature on hot or cold days — especially useful for making sure your pets are safe while you’re away!
- Monitor your fridge and freezer for safe food storage temperatures
- Check your 12V batteries for low or high voltage
- Set text message and/or email alerts for when temperatures get too hot or voltages are out of range
- RV Whisper® monitors your RV using wired and wireless sensors
- Display your RV data in a browser on your phone, tablet, or computer — no internet access is required to access your data when you’re near the RV Whisper® computer
- If you choose to supply your own WiFi, you can check in on your RV over the internet!
RV Whisper® Monitor Systems are easy to install. By using wireless sensors, you avoid the complexity of running wires throughout your finished RV.
RV Whisper™’s wireless sensors use Bluetooth Low Energy (BLE) to send data to the RV Whisper® Monitor System, where the data is stored.

Sensor-data history can be graphed to track various operations in an RV, a home on wheels. RV Whisper® allows RV owners to truly understand their home.
Peace of Mind With Customizable Unlimited Alerting
Has the temperature of an RV living room risen too high while the owner is away? Is battery voltage dropping too low? Customizable alerts can help an RV user take action to correct a potentially unsafe condition. RV Whisper® allows a user to take control to meet specific needs. Alerts can be sent as email to multiple email addresses and as text messages to multiple cell phone numbers. There is no limit on how how many Alerts can be configured and how many email addresses or cell phone numbers to send them to.
More Freedom with Internet Accessibility
When RV Whisper® is connected to the internet via owner-supplied WiFi, all monitoring and alerting features are available no matter the distance between the user and the RV. As long as a remote user’s smartphone or other device has internet access, the user can securely access RV data online.
Always On: When Powered by 12V RV Battery System
The 12V battery system is the most reliable source of power on most RVs. Most RV systems – propane-powered refridgerators, propane water heaters, 12V lighting, slide motors, awning motor, and electric jacks – are typically designed to run off of the 12V battery system installed in an RV. This allows an RV to be functional while traveling and when camping at sites without electricity.
Shore power can be unreliable at camping sties with electric hookups. Connected to the 12V battery system, however, RV Monitor can continue data collection and alerts even when shore power is lost. Remote access and alert features will work without shore power as long as RV Whisper® internet access is through a MiFi-type system on an RV that is also connected to the 12V system for power.
If the RV has solar panels that keep the 12V battery system charged during storage, RV Whisper® can continually monitor data and provide remote access over the internet – especially if a 12V-powered MiFi-type solution is also running in the RV.
