Deye Inverter (Local)

Monitor your Deye solar inverter directly on your local network — no cloud account, no internet dependency. This app communicates with the Solarman Wi-Fi data logger stick using the SolarmanV5 protocol over TCP port 8899, polling your inverter every 60 seconds. SUPPORTED MODELS - Deye Microinverter 2 MPPT (SUN600G3 / SUN800G3 / SUN1000G3) - Deye Microinverter 4 MPPT (SUN2000G3) - Deye String Inverter 3-phase, 2 MPPT - Deye Hybrid Inverter with battery, 2 MPPT - Deye Hybrid Inverter 3-phase SG04LP3 (SUN-8K / SUN-10K / SUN-12K-SG04LP3-EU) REQUIREMENTS - Homey Pro (firmware 13.0 or later) - Solarman Wi-Fi data logger stick connected to your local network - TCP port 8899 accessible from Homey (no firewall blocking) AVAILABLE DATA Depending on inverter model: - Real-time AC output power (W) - PV string voltage and current per channel (PV1–PV4) - Grid voltage, current and frequency - Inverter temperature - Daily and total production (kWh) - Battery power, voltage, current and state of charge (hybrid models) - Grid import / export energy (hybrid models) - Load power consumption (hybrid models) - Fault / Alarm state HOMEY ENERGY Fully integrated with Homey Energy. Your inverter appears as a solar panel device and contributes to your energy dashboard automatically. PAIRING 1. Open Homey and add a new device 2. Leave the IP field empty to auto-discover loggers on your network, or enter the IP manually 3. The logger serial number is detected automatically (or enter it manually from the sticker) 4. Select your inverter model from the list 5. Capabilities are configured automatically based on your model NOTES - Local communication only — no Deye cloud or SolarmanCloud required. - Auto-discovery uses UDP broadcast on port 48899 (Solarman discovery protocol). - Night-time detection pauses polling between sunset and sunrise to avoid false unavailability alerts. - Inverter definitions based on the home_assistant_solarman open-source project.

Energy Summary

What’s new

Version 1.4.16 — Fixed: negative values (battery and grid power, battery current) were 1 unit too small, e.g. 10 W on SOFAR. Fixed: changing the logger IP, model or polling interval (device settings or Repair) only took effect after an app restart, and only on that device — it now applies immediately to the inverter, battery and meter of the same logger. Pairing and Repair no longer collide with the app's own polling on the logger. Deye string inverters: load and grid power (advanced sensors) were 10x too small, and grid power now reads positive when importing, like the hybrid models (per Deye Modbus V118). Deye single-phase hybrid: load power can now be negative instead of jumping to ~65,000 W. "Restore capabilities" on string inverters no longer adds the optional load/grid/energy sensors, which need a CT meter (without one they read 0 or repeat production). New maintenance action on string inverters, "Remove unused values", removes those values, PV3/PV4 inputs that are not wired and a radiator temperature the inverter does not report (-100 °C). Fixed: device Flow triggers (solar production started/stopped, battery charging/discharging, grid export/import, fault, logger offline/online, data updated) never fired. Fixed: unwired PV3/PV4 voltage/current came back on every app restart. "Solar production stopped" and the daily summary now also fire when the inverter goes offline at dusk before production dropped below 5 W, and no longer flip between stopped/started when power hovers around a few watts at dusk (started again only above 25 W). String/micro inverters: a logger that loses power within an hour of sunset or sunrise is treated as night, so there is no daily "Connection failed" warning at dusk; retry attempts no longer fill the diagnostic log. New device setting "Debug logging" (Advanced): when asked for a diagnostic report, turn it on for the device with the problem — it logs every poll and request for that device's logger only, and switches itself off after 60 minutes.
