I finally got it to see the wifi module but still can’t see the inverter or get any information about my system. Just shows everything a “0”. Seems like the only good reviews this has gotten is from people that are asking questions not reviewing this worthless app. It’s unfortunate as I really like my sungoldpower inverter. ### 2/5 — Missing Content *2025-08-21* Over all good experience but from june 2025. Today Generation missing from the app only Total Generation is showing previously shows today, monthly and yearly generations ### 3/5 — Good, not great *2025-07-08, version 2.1.0* Been using this app for years and it is perfectly serviceable, however the lack of real time information in this day and age is very disappointing. I use a number of other apps that update in real time so should be easily doable, instead it takes a snap shot of the moment you log in and will not update for around 10 minutes. Please bring this app into 2025 ### 1/5 — Needs some work!! *2025-06-27, version 2.1.0* It doesn’t show live reading from inverter, should show real time statistics. Its 15 minutes back against inverter. ### 4/5 — Please add siri *2025-06-15* Hi, great app, just consider adding siri shortcuts that users can setup to ask siri about specific things, like the battery percentage, faster and without checking the app, that would be awesome ### 5/5 — Suggestion *2025-05-16* Please add alerts to the program, such as notifications when the national electricity is on or off, notifications when the battery is full, and any other alerts you find necessary. Thank you. ### 2/5 — User interface *2025-04-05, version 2.1.0* I am surprised that it has a poor old looking user interface and the developers can’t improve it. Just see the interfaces of your competitors? Yours is primitive with no summaries and graphs ### 3/5 — Not bad. Not great *2025-03-20* Recently the Overview tab show Total Power for the day, which is really useful. Would be even better if it showed historical data for past days, weeks and months. App works well enough for what it is but could be so much better. I wish there was an option to automatically let me login. An unnecessary step to have to login each time. ## Frequently asked questions about WatchPower ### What does WatchPower do?
