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.

I really want to love this device but I have only had it for a week and am already having issues. The fact that as soon as you a few feet away, it sends you a notification that it is disconnected. The first time I received this, I freaked out thinking that the system had shut down. Now I know better. Secondly, in the past few days the wattage and amps have been showing higher than what I’m actually using as if I have the devices in when they are off. Example, I use a space heater and occasionally I turn it off during the daylight hours. The Watchdog will still show the space heater being used although it is powered off. This also happens when I use my microwave as well. I have attempted to “reset” the device through the app to no avail. I usually have to wait about 10 minutes before I am able to actually reset the app. I do not want to turn the device(s) back on so that the app won’t think I have went over my apps and turn everything off. I would love to know what is the fix for this issue.
