Just bought the Hughes PWD50-EPO power WatchDog

I just bought the PWD50-EPO. I choose it since it monitored for low and high voltage with automatic disconnect and had a user replaceable surge module. The Blue Tooth phone interface was just an added benefit. Although I haven't used it with a 50a pedestal yet, I did test it with a 15a garage outlet and a portable generator. Here are some items I noted during my tests

1. The L1 / L2 data on my phone were opposite what my internal EMS reports. The values were very consistent. The WatchDog report precision is to 1/10 of an amp, where my EMS is whole amps.
2. The Blue Tooth reaches anywhere in my RV. Better than I expected.
3. Using the portable generator, WatchDog reported "E7: Missing ground". Made sense to me. I added my Neutral/ground bonding plug to the generator and after about 90 seconds the WatchDog turned on with OK power. Then when I removed the plug the WatchDog reported "E6: L2 and neutral reversed" ... doesn't make sense to me, but it did disconnect the RV.

So far I'm pleased with my purchase.

The bluetooth is the most valuable benefit for me. You'll quickly learn what everything in the coach draws, and which leg it's on. I rebalanced a few loads in my breaker panel , tayloring them to how I use the coach.
