Would you like to get an email or text message when your RV loses shore power? If you depend on the RV air conditioner to keep your pet safe, or your RV fridge depends on shore power to keep your food safe, then the answer is probably yes.

Luckily, the RV Whisper Monitor Station provides two ways to detect when shore power is lost from your RV so alerts can be sent to your phone:

Battery Voltage & Temperature Sensor (BMRV1)

BMRV1 – If your RV does not have solar panels, then you can most likely use the BMRV1 battery voltage sensor. Simply create an Alert Trigger called “Shore Power Disconnected” that will trigger when the battery voltage is less than 13.0 Volts for more than 5 minutes. When you add a BMRV1 sensor with RV Whisper software V3.0 or higher, this Alert Trigger is automatically created for you. However, note that if you use solar panels to keep your RV batteries charged, this technique will not work because the voltage may not drop below 13.0 Volts if shore power is lost during daytime; the solar panels may keep the battery voltage higher.

Power Watchdog 50 Amp

Power Watchdog Surge Protector – For a foolproof way of detecting shore power lost from your RV, add any one of the Power Watchdog brand of Surge Protectors to your RV as another “wireless sensor” to your monitor station. When adding a Power Watchdog as a wireless sensor, appropriate alerts are automatically created for you including a shore power lost alert.

Being alerted to “Shore Power Lost” gives you an early warning system that the RV inside temperature and/or the RV fridge temperature may soon reach unsafe levels. Your pets and your potato salad will thank you.
