Here is a smart surge protector designed to shut power down to your RV when abnormal spikes are detected. The Power Watchdog 30 Amp Bluetooth Surge Protector has a plug & play design. It combines with your phone to let you monitor volts, amps, and watts wirelessly.
This surge protector has a 90-second power-on delay to protect your appliances. It lets you know if power conditions are safe after just 4 seconds. You get text alerts when dangerous conditions are detected. With the optional RVWhisper add-on, you can monitor everything from miles away.
