Live values
| Area | Values |
|---|---|
| Solar | PV1 and PV2 voltage, current and power, total PV power |
| Battery | State of charge, voltage, current, power (charging or discharging), temperature |
| Grid | Voltage, frequency, import or export power per the inverter’s CT |
| Load | House consumption, backup (load port) power |
| Inverter | Output power, internal temperatures, running state |
| Faults | Active alarm and fault codes, translated |
Daily energy totals
- Solar production today
- Battery charge and discharge today
- Grid import and export today
- House consumption today
These come straight from the inverter’s own counters, so they match what the inverter displays.
Single-phase and three-phase
Single-phase low-voltage hybrids and three-phase models use slightly different register maps. Tell us your exact model (from the label) when you order: the box is prepared and tested for it.
Where to see it
- Screen on the box: PV, battery SOC, grid and load at a glance.
- Local dashboard at
http://moniwatt.local, password protected. - Home Assistant through MQTT discovery.
- JSON API for Node-RED, Grafana or your own code.
- Remote dashboard, optional, with history and offline alerts.
What it leaves alone
MoniWatt for Deye only reads. It does not change work mode, time-of-use slots, export limits or battery settings. Your Solarman logger can stay in place; it uses its own port.
