Colour theme is terrible. Please bring back old theme. Graphs are not very user friendly and prefer the older version for ease of use. Before I would quickly see daily usage, now it’s much harder to follow and nowhere as simple as before. ### 2/5 — Dark mode *2025-10-26, version 1.12.1* Despite all known sftw bugs that Goodwe struggles or isn’t willing to fix, I wonder why still no dark mode is available? ### 2/5 — Please add landscape orientation! *2025-10-23, version 1.12.1* While the app is an improvement, it’s still unfortunately lacking landscape mode. Please enable landscape on all platforms so it displays correctly on horizontally docked devices being used as a hub for smart homes. Really annoying!!! ### 5/5 — better than older version *2025-10-02, version 1.12.1* this new app is very nicely developed. have all what i need to complete daily power monitoring. if possible, please add more rate schedule from different utility company. ### 2/5 — Offline notification *2025-08-27, version 1.11.0* It would be really beneficial if there was a notification capability to inform owners when the solar is offline. The end of day report is too late. ### 1/5 — Not an improvement *2025-08-19, version 1.11.0* Don’ bother with SEMS+. The charts are not as clear, the bar charts appear to only compare 2 years and not all years. The presentation is insipid(dull and uninspired). I have deleted this version and will continue to use the original. ### 2/5 — Changed graph *2025-08-18, version 1.11.0* Why the change to the graph? Full colour to a line. Graph looked more positive. I know it doesn’t matter, but why change. ### 5/5 — App update 3 days ago *2025-08-12, version 1.11.0* App is not collecting data after the app update 3 days ago. How do I fix this? ### 3/5 — Could be better *2025-08-10, version 1.11.0* The app is useful but there are two improvements that would make it so much better: 1. The new colour scheme for the power graph is terrible. All the colours are almost the same! Please change it back. 2. Allow multiple logins. My husband and I both like to monitor our usage and keep logging each other out. ### 4/5 — Useful App *2025-08-09, version 1.11.0* The color changes to the graph in the latest version are not very good. The previous colors were better. Please bring it back. Overall good useful app. ## Frequently asked questions about SEMS+ Classic ### What does SEMS+ Classic do?
