Saved us a few times

If you travel to places with lots of 30a sites in older parks this is a lifesaver…coach system saver actually. In more than a few parks, commercial and public, the older 30a systems will not maintain above 106v when you get much over 20a draw. With newer large coaches, especially the all-electric models, the coach can manage the load by turning things on and off or diverting to the inverter if necessary. We never would have known the shore voltage was dropping below 106v if it hadn’t been for the device dropping the power to protect the coach electrical. It allowed us to set the coach max load to 20a so it knew to start limiting the load before the voltage dropped. For the reviewers that say it’s junk because it keeps tripping off, would you rather have a burnt out air conditioner?? Read the manual and learn your rig!!

So why 4 stars, not 5? App has been improving but still needs work - when there’s a voltage error, provide the specifics in the error message (voltage, current, time stamp) to help troubleshoot the problem. Wifi capability so we can connect to our coach internet connection and get alerts remotely. Reading for total current being drawn. If app is set for only one Watchdog, bypass confirm screen to reduce clicks to operate. Graphical view of voltage and current would be nice but not mandatory. I’d recommend this unit to others!

Good but needs updating

I've had the 50 Amp non-EPO and now the 50 Amp EPO app and the EPO app is lacking the ability to monitor Amps like the non-EPO can for some reason. Also, the biggest annoyance (for me) is the "Disconnected" notification which simply means you are out of bluetooth range. My camper is stored within 30 feet of my house so I get this alert VERY often. As a matter of fact, it depends on where in my house I am. Yes, you can go into your iPhone Notifications and turn Notifications off for the Watchdog App but that turns ALL notifications off. I'd like to know if there is an anomaly. Having the ability to pick and choose which alerts you want to receive would be HIGHLY appreciated. Other than that, the app does what it's supposed to do. Seeing the current amp draw and voltage is a strongpoint. Just wish it could be more "adaptable" to individual needs. Watchdog itself (my prior one AND this one) work PERFECTLY BTW. None better!

Very noisy notifications

The app offers very basic information about the status of the surge protector. We’ve been testing it on our first trip with our new RV and it has cut the power twice on us for going over current. I don’t know how accurate the meter is on the EPO itself, but that is a separate review :) the app made it very easy to check why the power cut off and to turn it back on right from my phone. Never needed to go outside of the RV!

Knocking some stars because when I had notifications turned on it was incredibly noisy, pinging my phone every few minutes that it disconnected. I don’t know what that alert meant: that my phone disconnected from the EPO, or that the EPO power had disconnected? Either way, power never appeared to be disrupted in the RV so I assumed it was an app issue. The app has no option to configure notifications (no options to configure anything, really), so my only choice was to disable all notifications completely from iOS. This meant I had no notifications when the power cut off and had to figure out what happened on my own. Would be nice to configure some settings like what notifications I want to see and adjust some thresholds for power off.
