SEMS+

the control options are easy to use and have worked very well for me. i manage 3 different TOU tariffs and have no problem configuring the system for what I need. the data metrics that the app displays are all absolute rubbish. grid imports to the battery are double counted as consumption when imported to the battery and again later when used by the load. this skews all other data. all solar generation is counted as revenue, rather than just what is exported to grid. the app crashes constantly.

It's an excellent app that is easy to use. I noticed that the new "Off-grid" mode option under the working mode is useful when you are experiencing fluctuating grid voltage. However, I also prefer if the "Self-consumption" mode can set the inverter to run "Off-grid" mode automatically when there's enough battery capacity, solar power is available, and the export power limit is set to 0. Alternatively, you may add an option under "Off-grid" mode to set time periods to activate it.

This newer app is very poorly designed & times out when trying to set EV charger settings. The old Sems app was more reliable than this one. I constantly have to login via web browser to change settings as the sems+ app won't work properly. (On galaxy S23).
