Home assistant integration for the Sungrow API

In Apple Home through HomeKit Bridge

What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

Entity	Shows up as	Note
`binary_sensor`	Sensor (motion, contact, leak, smoke…)
`sensor`	Sensor (temperature, humidity, air quality…)
`select`	Mode picker (as switches)

What people report

Sungrow iSolarCloud integration with an optional local Modbus path via WiNet dongles. Local works well on SG-RS inverters; hybrid SH models are still being mapped.

Sungrow SG3.6RS with WiNet-S	Works Local		Local Modbus TCP validated on real hardware, discovered via mDNS Saved copy Discovery, it's zeroconf (mDNS), not DHCP Correction to earlier thinking: the WiNet-S MAC OUI is Espressif (its Wi-Fi chip), not Sungrow, so DHCP-by-OUI would false-match every ESP device on the network. Bad hook. But the WiNet-S advertises mDNS/zeroconf, which is clean and distinctive: - Service: `WiNet-WebServer`, `_http._tcp.local.`, port 80 - Hostname: `SUNGROW .local` - TXT records describe the whole rig: - `board=SUNGROW;1;WiNet-S; ;1;` - `inverter=1;9732; ;1;516;SG3.6RS;1;1;` ← type code + model (SG3.6RS) ### HA zeroconf discovery ```json "zeroconf": [{ "type": "_http._tcp.local.", … Excerpt saved from GitHub on 2026-10-23.

Devices listed in its README

Regions / gateways: Europe, International, China, Australia, and India. Pick the one matching the account you registered your developer application under.

Limitations from the README

Cloud-only. All data comes from the iSolarCloud cloud API, there is no local polling. If iSolarCloud is unreachable, or your account/plan loses API access, entities become unavailable.
API quota. The free developer plan allows ~2000 calls/hour; keep the polling interval sensible, especially with many sensors.
Dispatch needs compatible firmware and plan. External EMS / parameter setting requires an inverter and iSolarCloud plan that permit it. Where unsupported, dispatch entities may error on write.
Developer app approval. New iSolarCloud developer applications must be approved by Sungrow (with OAuth 2.0 enabled) before authorization works, this can take up to a week.

In ReReHome

Whatever HomeKit Bridge shares reaches Apple Home as normal HomeKit accessories behind your Home Assistant bridge, so ReReHome shows and controls them like any other.

Bridges get their own settings page listing the accessories behind them.
