### 5/5 — Helpful tool for RV

*2026-04-11, version 3.2.0*

We have returned to an RV site for the thrift time, always getting the same spot. This third time, the pedestal has a short in the 50amp plug and breaker. The watchdog helped me identify the problem and we were able to notify the owners for repair. I love the WiFi connection although I didn’t expect yo ever use it.

### 3/5 — NEED HISTORY DATA

*2026-02-16, version 3.2.0*

Just like everyone else… would really love a history log with timestamps for usage, error codes, outages etc. 
Great for real time, but we really want history of power data and errors!

### 3/5 — App needs updating

*2025-10-10, version 3.2.0*

As many have already stated, the app is very outdated and needs to be updated!
Device works as stated, reduces initial power draw, but it would be beneficial to have a graphic history and a note area to record power draw from different devices. We all have those pieces of paper with the amperage of all our different devices!!! Especially when on 30 amp!

### 3/5 — Lacks Historical Time-series

*2025-10-09, version 3.2.0*

PowerDog hardware is wonderful & works as expected, protects RV & everything plugged inside from external power chaos - which is great.

the app shows you real-time usage & detailed error reports when something happens. it is however missing one major, and IMO obvious feature - a timeseries graph showing a data log of kwH. I want to be able to see how the demand goes up and down - not in realtime & take notes inbtw turning components on/off - i wanna be able do log & graph historical power draw. 

make it happen please!

### 3/5 — No history??

*2025-09-26, version 3.2.0*

Mine dropped out for a couple of minutes. Opened app after power came on but app shows no history, no reason for dropping power…..

### 4/5 — Awesome device, but app needs updating.

*2025-08-30, version 3.2.0*

New icon is silly. BLUETOOTH!

Really glad we upgraded to a PWD, but can we please get error logging in the app? I love that my watch will give me updates when there’s an issue, but why can’t we have the issues logged? Logging would make this pretty much perfect.

### 1/5 — App is useless

*2025-08-09, version 3.1.8*

The app is useless. Watchdog itself is great- had an E3 power loss- would assume the app would indicate I had lost power & have alert code definitions- but no. No history, no codes, nothing. Why have an app that does nothing?

### 1/5 — Can read QR code

*2025-07-30, version 3.1.8*

Open the app try to read the QR code on the unit. Error that it can’t read the code. No help available to figure out what’s wrong.

### 5/5 — Peace of mind

*2025-07-29*

I have my 30 AMP unit for seven months now and gave take it from NJ to Florida twice and Florida to California and am in Tennessee on my way back to NJ now. That’s a lot of miles and numerous campgrounds. 
It gives me comfort knowing that I won’t fry the electronics in my camper. The cost of the unit is less than the deductible and don’t lose the camper for an undetermined amount of time.

### 4/5 — Alerts when 999kwh used

*2025-07-23, version 3.1.8*

I have written to the company about this problem and they haven’t fixed it yet. This unit keeps track of energy usage. I use this for understanding how much my RV uses monthly. The device alarms through the app when you have reached 999kwh. I want to remove this. I check the app end of each month for my usage, but on particularly hot months, the rv uses closer to 1200-1300kwh causing an alarm in the app. Sometimes this happens in the middle of the night. Other than that, I love the surge protector.
