Before you buy, read this:
- RoamVitals reads the Power Watchdog and never writes to it. It gates your shore power, so we do not send it commands. Your surge protection behaves exactly as it did before.
- Verified on a single-line 30 A unit. The 50 A models report L1 and L2 as separate frames, and the Gen2 Wi-Fi-plus-Bluetooth units have not been on our bench either. We expect both to decode; neither has been confirmed here yet.
Where to get one
Hughes Power Watchdog (30 amp)
For a 30 amp rig, which is most travel trailers and smaller fifth wheels. Reads voltage, current, power, energy used, line frequency and error codes over Bluetooth, so a pedestal disconnect reaches your phone instead of only its own screen.

Hughes Power Watchdog (50 amp)
For a 50 amp rig, which is most large fifth wheels and Class A motorhomes. Reads voltage, current, power, energy used, line frequency and error codes over Bluetooth, so a pedestal disconnect reaches your phone instead of only its own screen.
