Local monitoring for Hoymiles DTU-WLite, DTU-Pro and DTU-Pro-S microinverters. No cloud required. Connects directly to the DTU over your local network using the open-source hoymiles-wifi library. Supports single-phase, three-phase and hybrid (battery storage) systems with automatic detection.
Note: if you are upgrading from a previous version, please remove the existing device and add it again (re-pair).

What’s new
Version 1.1.26 — Fixed hybrid (energy storage) systems showing no values at all — every poll failed on fields that don't exist in the storage data. Power, Lifetime Energy and battery level now update; the battery level is a true average across inverters. Removed the Daily Energy tile on hybrids, which never had a value (the storage data has no daily field). Pairing now refuses a hybrid gateway whose inverter list can't be read, instead of adding a device that never updates. Added a "Restore capabilities" button (device settings → Maintenance) that re-adds missing tiles with their correct names — no re-pairing, Flows and Insights are kept. Changing Panel Count or Three-phase in the settings now adds the matching tiles right away. The panel count is no longer lowered on restart, which froze some panel tiles. Fixed yesterday's Daily Energy showing in the early morning for locations east of UTC+5 (e.g. Asia, Australia). Changing Solar latitude/longitude now takes effect right away instead of the next day. New optional "Nominal power (W)" setting: when set, adds a Power Ratio (%) tile (current power ÷ nominal power), handy for Flows such as "production below 10%". Repair: a new DTU IP address now takes effect immediately (it used to wait up to 20 minutes for an automatic reconnect). Fixed: device Flow triggers (solar production started/stopped, daily data updated, data updated, fault detected) never fired. "Solar production started" now needs more than 25 W (it fired at dawn on 5 W), and "stopped" needs three low readings in a row, so a single 0 W reading from the DTU mid-day no longer fires stopped + started; at night "stopped" and the daily summary also fire when the inverter falls asleep first. New device setting "Debug logging": when asked for a diagnostic report, turn it on for the DTU with the problem — it logs every poll and request for that DTU only (never the Wi-Fi password or encryption keys) and switches itself off after 60 minutes.
