Your Deye inverter at a glance – real time, at home, no cloud
Deye-HomeMonitor reads data straight from your inverter's Wi-Fi logger and shows PV production, battery, house consumption and grid on a photorealistic scene of your home.
- No cloud, no manufacturer account – your data stays in your network
- No extra hardware – the LSW-5 logger you already have is enough
- Read-only – the app never writes to the inverter
Registration is free for early customers – we approve licences within a few hours.
