RV Whisper

RV Interior Temperature Alerts

When your pets stay behind in your RV, you can 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 warn RV owners. RV owners can use a web-enabled browser to remotely view the RV’s current interior temperature. Use the RV Whisper™ software to plot graphs of your RV’s temperature over the last few hours, days, or week so they can know what the RV interior temperatures have been like when they are away.

RV Whisper™ is designed to be powered from your 12V battery bank to 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 generator auto start, 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 RV Whisper™ and your Internet Access (MiFi) device are both operated from your RV battery bank.

Refrigerator and Freezer Temperature Alerting

Food refrigeration tends to be more challenging in RVs than in stick-and-brick homes. Propane / Electric fridges that are commonly used in RVs can sometimes struggle to keep food at safe temperatures in hot weather. With RV Whisper™, you will know if your fridge is storing your food at safe temperatures. If the refrigerator temperature remains 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 can be very useful for 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.

Monitor Battery Bank Voltage and Temperature

Monitor your 12V battery banks with wireless sensors that connect to your RV batteries and monitor their voltage and temperature. Customizable alerts 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 Monitoring System installed on the RV and receive email and text message alerts.

What is RV Whisper?

RV Whisper is built around a low-cost computer that can be installed easily by an RV owner with just a screwdriver. RV Whisper is perfect for all RV enthusiasts — from the casual weekender, to the seasonal camper, and even the full timer.

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 online!

View historical data to learn about your RV

RV Whisper collects data such as temperature, humidity, and battery voltage from both wired and 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.

Easy Installation

RV Whisper systems can be installed either aftermarket or at the factory. Factory installation allows easier installation of lower cost wired sensors, whereas aftermarket installations will typically use more wireless sensors to avoid the higher cost and difficulty of running wires through a finished RV.

Benefits of RV Whisper

More Insight with Historical Data Access

RV Whisper systems bring the Internet of Things to the RV world, promising new levels of data and insight to the diverse community of RV enthusiasts.

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 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.

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: 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.
