About LmarSys.
LmarSys reads your inverter through its Wi-Fi data logger and shows you what is happening right now: how much your panels make, how full your battery is, whether you are using grid power, and how much your home uses.
It starts with Deye-based inverters that use a Solarman Wi-Fi logger, such as Inverex, Deye and Sunsynk units. More brands may follow later, because each brand needs its own setup.
Your inverter data stays on your own network. LmarSys does not need an account and does not send your readings to us.
Where it stands: the dashboard has been tested only with a simulated logger. It still needs testing on real inverters, so some values may need adjusting on your unit. A PC version (early, free) can be downloaded below. The Android app is planned and has no store link yet.

It needs Python on a Windows, Mac or Linux computer on the same Wi-Fi as your inverter. Unzip it and follow the README inside.
LmarSys is not affiliated with or endorsed by Inverex, Deye, Sunsynk or Solarman. Those names are used only to say which inverters it is designed to work with.
