It has 120 installs sharing analytics, needs the vendor's cloud and was last updated October 26, 2026. Sunsynk / Deye Solar Inverter is a custom integration that monitors and controls Sunsynk and Deye hybrid inverters through the Sunsynk cloud API. It adds sensors for PV generation, battery state, grid import and export, and load, plus per-phase values for 3-phase systems and every MPPT string it finds. Number, switch and text entities let key inverter settings be changed from Home Assistant, such as battery thresholds, charge and discharge current, time slots and sell power limits. Optional extras include a solar forecast based on Open-Meteo, a tariff manager that charges at cheap rates and discharges at peak rates from a price sensor, and a virtual slot scheduler. One entry can cover several inverters, including parallel groups, and control actions can be limited to administrators. It needs the vendor's cloud, so the inverter must already be connected through the Sunsynk dongle, and it is set up in the UI.

Enter a new password after changing it in the Sunsynk or Deye portal. - **Inverter Serial Number(s)** - **Refresh Interval (seconds)** - **Create and maintain Sunsynk dashboard**: Opt in to creating a Lovelace dashboard, registering the bundled card resource, and updating that dashboard on each integration reload. Disabled by default. - **Allow only administrators to use control actions**: When ticked, the Sunsynk control actions (force charge/discharge, work mode, virtual slots) can only be run by Home Assistant administrators. Automations and scripts are unaffected. Only administrators can change this setting. - **Latitude (Solar Forecast)**: Optional — defaults to your HA home location - **Longitude (Solar Forecast)**: Optional — defaults to your HA home location - **Panel Peak Power (kWp)**: Total installed panel capacity in kilowatt-peak. Leave blank to disable solar forecast. - **Performance Ratio (0–1)**: System efficiency factor, default 0.80 - **Import/Buy Price Sensor**: Any sensor reporting electricity price (e.g. Octopus Agile, NordPool, Tibber). Leave blank to disable tariff management. - **Export/Sell Price Sensor (optional)**: Drives discharge/sell decisions instead of the import price above — for tariffs where import and export rates aren't linked (e.g. Octopus Intelligent Go + Outgoing). Leave blank to use the import price for both. - **Charge below price (cheap rate threshold)**: When price ≤ this value, charge the battery. Leave blank to disable cheap-rate charging. - **Charge current at cheap rate (A)**: Battery charge current during cheap period (e.g. 100 A). Texts from the code of [MarcinG81/SunSynk\_HA\_Integration](https://github.com/MarcinG81/SunSynk_HA_Integration). ## Troubleshooting - **Diagnostics**: Downloads a diagnostics file to attach to a bug report. - **Repair notices**: Notices it can show in Settings, Repairs: Sunsynk authentication failed ## From the README > A native Home Assistant integration (not an add-on) for monitoring and controlling Sunsynk and Deye hybrid solar inverters via the Sunsynk cloud API. > > Note: This integration communicates with the Sunsynk cloud API (api.sunsynk.net or pv.inteless.com).
