GREE Controller API reference
HTTP and WebSocket API for GREE Controller 0.11.0.
Base URL and content type
Default local address:
http://127.0.0.1:8787
JSON requests use:
Content-Type: application/json
If GREE_CONTROLLER_BASE_PATH=/gree is configured, every HTTP and WebSocket path below is prefixed with /gree.
Authentication
There are three access levels.
Public
No token is required for:
GET /api/health
GET /
GET /index.html
GET /app.js
GET /theme-init.js
GET /styles.css
GET /manifest.webmanifest
GET /sw.js
GET /favicon.svg
GET /lang/index.json
GET /lang/{file}
Administrator API
All normal /api/* routes are administrator routes. If GREE_CONTROLLER_APP_TOKEN is empty, the controller intentionally operates in trusted-LAN mode and these routes do not require authentication.
When an app token is configured, send either:
Authorization: Bearer APP_TOKEN
or:
x-api-token: APP_TOKEN
Example:
BASE='http://127.0.0.1:8787'
TOKEN='replace-me'
curl -H "Authorization: Bearer $TOKEN" "$BASE/api/bootstrap"
Restricted Home Assistant API
Generated Home Assistant access tokens always authenticate only the restricted integration surface under /api/integrations/home-assistant/*. The administrator app token is also accepted there.
Generated token secrets are returned only at creation time. SQLite stores their SHA-256 hash and a display prefix.

POST /api/discovery
Request body, all fields optional:
{
"timeout_ms": 6000,
"broadcast": "255.255.255.255:7000",
"protocol_version": 0,
"passes": 3
}
Rules:
timeout_ms: effective range500..30000ms.protocol_version:0auto/both,1AES-ECB only,2AES-GCM only.passes:1..10.- Missing values use runtime GREE settings.
Successful discovery merges known devices, tries binding devices that do not have a key, persists results and returns:
{
"count": 1,
"devices": [],
"new_device_ids": ["gree-aabbccddeeff"]
}
GET /api/devices
Returns Device[].
POST /api/devices
Manual add request:
{
"name": "Living room",
"mac": "AABBCCDDEEFF",
"ip": "192.168.50.30",
"port": 7000,
"protocol_version": 1,
"key": null,
"simulated": false
}
Defaults: port=7000, protocol_version=1, simulated=false. MAC values are normalized. Duplicate MACs are rejected.
Returns 201 Created with Device.
GET /api/devices/{id}
Returns one Device or 404.
PATCH /api/devices/{id}
All fields optional:
{
"name": "Bedroom",
"ip": "192.168.50.31",
"port": 7000,
"protocol_version": 2,
"key": "optional-binding-key",
"enabled": true
}
key:null clears the key. Changing protocol version clears the existing key/capability cache so the unit can be re-bound cleanly. Disabling a device goes through the controller's safe disable path.
DELETE /api/devices/{id}
Returns 204. Deletion is rejected if the device is referenced by an automation or cannot be safely detached from thermostat ownership. Associated zones/groups are cleaned only after the safety checks pass.
POST /api/devices/{id}/bind
Performs/repeats GREE binding and returns updated Device. Simulated devices return unchanged.
POST /api/devices/{id}/poll
Immediately polls one unit and returns updated Device.
POST /api/devices/{id}/command
Direct/manual device control. This is deliberately different from thermostat-zone control.
All fields optional; at least one meaningful field should be sent:
{
"power": true,
"mode": "cool",
"target_temperature": 22,
"fan_speed": 3,
"swing_vertical": true,
"swing_horizontal": false,
"quiet": false,
"turbo": false,
"light": true,
"air": false,
"xfan": false,
"health": false,
"sleep": false
}
Rules:
- modes:
auto,cool,dry,fan,heat, - target temperature is normalized to the supported GREE Celsius range
8..30, - fan speed is
0..5, - optional feature commands should be used only when the corresponding
supports_*capability is true.
The backend sends only properties that differ from the last known device state. Climate-relevant direct commands can create/continue a manual-device takeover for an enabled thermostat zone so automation does not immediately fight the user.

DELETE /api/zones/{id}
Safely powers the owned device off before detaching thermostat ownership. Returns 204.
POST /api/zones/{id}/control
Manual setpoint values are retained with 0.1 °C precision. The physical GREE unit setpoint is still rounded to the whole-degree resolution supported by the protocol.

}
GET /api/groups
Returns groups.
POST /api/groups
{
"name": "Bedrooms",
"zone_ids": ["zone-1", "zone-2"],
"power_enabled": true
}
A group must contain at least one existing zone. Returns 201 Created.
GET /api/groups/{id} / PUT /api/groups/{id} / DELETE /api/groups/{id}
Read, replace or delete a group. DELETE returns 204.
POST /api/groups/{id}/control
{
"power": true,
"mode": "house",
"preset": "custom",
"setpoint": 22.3
}
All fields optional:
power: enable/disable group-level control (legacy field name; this is not a device power gate),mode:house,cool,heat,preset:auto,comfort,sleep,away,custom,setpoint: custom group target in the8–30°Crange; requirespreset: "custom".
A custom setpoint creates the same override for every member zone. For explicit Web/Home Assistant group control it stays active until the group is changed/released; scheduled group automation remains bounded by the normal schedule hand-back. Returns a group control/result object including updated members/state.
Group power is a scoped bulk-power/control action. power=false immediately powers member units off and releases group:* ownership; members are stored as individually-off thermostats rather than being blocked by membership in an OFF group. This group-created OFF is indefinite (no 15-minute local hand-back), so the regulator cannot restart the unit by itself; a user can still turn an individual thermostat back on independently. power=true clears that scoped thermostat-OFF state and immediately re-runs group thermostat arbitration. Explicit Web/Home Assistant group control has higher priority than house rules and schedules; scheduled group automations still respect higher-priority manual/local ownership. Group mode/preset/setpoint changes are accepted only while the group is ON. Global ON/OFF never creates a persistent global gate. Global OFF does leave member thermostats locally OFF until they are explicitly re-enabled by local/group/global ON.
Whole-house control
House thermostat rules and global power actions are intentionally separate. Global ON/OFF does not create a master automation gate; OFF is persisted as per-zone local OFF so ordinary demand cannot immediately undo it.
POST /api/house/control
{
"mode": "cool"
}
Valid modes: cool, heat, off.
cool/heatselect the house rule used by zones that inherit the global mode and immediately re-run arbitration for free zones. Explicit local/group/direct ownership is preserved.offmeans do not perform house-level thermostat control for inherited free zones. It does not block local thermostats, groups, device-manual control or controller automations.
Returns public runtime settings.
POST /api/house/power
{
"power": false
}
This endpoint is a bulk thermostat power action without a persistent blocking global gate. false first stores every thermostat as an indefinite local OFF and then sends immediate OFF to every technically enabled unit, so the next normal demand cycle cannot turn the house back on. A later per-zone Resume automation clears that local OFF but does not invent a Comfort demand: without an active schedule/override/temporary or another explicit intent the zone stays OFF. true is itself an explicit whole-house ON intent, releases local OFF markers for all thermostats and sends ON to all technically enabled units. Group enablement, profiles, schedules and house mode are preserved. Pending compressor-protection tasks from before the action are cleared. When compressor protection is enabled, protected global starts are queued until their safe deadline; OFF is never delayed.
Response includes:
{
"power": false,
"one_shot": true,
"devices": [],
"groups": [],
"settings": {},
"failed": []
}
POST /api/house/preset
{
"preset": "sleep"
}
Valid: auto, comfort, sleep, away.
A non-auto preset creates overrides for free house-controlled zones and normally expires at each zone's next schedule boundary. auto clears those free-zone overrides. Explicit local thermostat, group, temporary thermostat and direct/manual ownership is not overwritten by a house profile action.
Schedules
Schedule object/request:
{
"zone_id": "zone-1",
"name": "Night",
"enabled": true,
"weekdays": [1, 2, 3, 4, 5, 6, 7],
"start_time": "22:30",
"end_time": "06:30",
"preset": "sleep",
"setpoint": 24.5
}
Rules:
- weekdays use ISO numbers
1=Monday ... 7=Sunday, - times use local
HH:MM, - crossing midnight is supported,
start_time == end_timerepresents a 24-hour window for selected weekdays,- preset:

This endpoint is the best way for another client to understand desired vs actual state, who owns control, and why a zone is blocked/paused.
Events and retention
GET /api/events?limit=100
Response:
{
"events": [
{
"id": 1,
"timestamp": "...",
"level": "info",
"kind": "device.updated",
"message": "...",
"metadata": {}
}
]
}
GET /api/events/retention
{
"days": 30
}
PUT /api/events/retention
{
"days": 30
}
Value is clamped to 1..3650; pruning happens immediately. Response includes days and number of removed rows.
Runtime settings
GET /api/settings
Returns a public-safe settings document. Secrets are blanked and accompanied by *_configured booleans where relevant.

}
}
default_entity_id is primarily the entity used by the Home Assistant connection test when the request does not provide another entity. Thermostat zones use their own configured ha_entity_id; this setting does not automatically become a zone temperature source.
InfluxDB settings

PUT /api/settings
Accepts the complete RuntimeSettings document. Important behavior:
house_modecannot be changed here; use House Control API.house_power_enabledis a legacy compatibility field and is normalized totrue; global ON/OFF no longer uses a persistent master gate.- polling interval is clamped
2..3600seconds. - zone interval is clamped
2..3600seconds. - discovery timeout is clamped
300..30000ms. control_strategyis normalized tosetpoint.- discovery broadcast must be
auto,auto:*or a valid socket address. - blank HA token preserves the saved token.
- blank Influx token/password preserve saved secrets.
- blank Pushover/Slack/Discord secret fields preserve saved secrets.
- HA sensor age is clamped
30..86400seconds. - notification cooldown:
30..86400seconds. - communication failure threshold:
2..100. - target timeout:
5..1440minutes. - retention windows:
1..3650days. - night mode times must be
HH:MM; max fan is clamped1..5.
Returns the safe public settings form.
GET /api/settings/export
Returns configuration format version 1:
format_version
exported_at
settings
devices[]
zones[]
groups[]
schedules[]
automations[]
Export includes GREE binding keys and integration credentials. It excludes metric history, event rows and generated API-token records. Treat the export as a secret.
POST /api/settings/import
Accepts exactly the export document. The backend validates IDs/references/schedules/settings, safely stops devices whose ownership is being removed, clears transient ownership/timers/stale live state, replaces configuration, re-polls devices, then re-enables thermostat control.
Metric/event history and generated access-token records are preserved.
Response:
{
"ok": true
}
Debug API
GET /api/debug
{
"overlay_enabled": true,
"gree_frames": true
}
PUT /api/debug
Accepts the same object, persists it and broadcasts debug.settings.
When overlay diagnostics are enabled, live HTTP requests generate api.request WebSocket events containing method, path, status and duration. When gree_frames=true, sanitized GREE protocol events are also sent as gree.frame.
The Web UI can display All, Requests or GREE subsets.
Integration tests
POST /api/integrations/home-assistant/test
{
"entity_id": "sensor.room_temperature"
}
entity_id is optional; controller defaults/aliases are resolved. Response:
{
"ok": true,
"temperature_c": 23.4,
"entity_id": "sensor.room_temperature"
}
POST /api/integrations/home-assistant/entity
Reads the current raw Home Assistant entity document used by the shared-Flow-input diagnostics UI.
{
"entity_id": "climate.gas_boiler"
}
Response includes the raw state, availability, attributes and timestamps:
{
"ok": true,
"entity_id": "climate.gas_boiler",
"state": "heat",
"available": true,
"attributes": { "hvac_action": "heating" },
"last_changed": "2026-09-02T06:30:00Z",
"last_updated": "2026-09-02T06:30:05Z"
}
POST /api/integrations/notifications/test
Accepts a NotificationSettings object. Blank secret/webhook fields reuse saved secrets for the test.
Response:
{
"ok": true
}
Access tokens
GET /api/access-tokens
Returns:
[
{
"id": "uuid",
"name": "Home Assistant",
"token_prefix": "gree_controller_abc...",
"created_at": "..."
}
]
POST /api/access-tokens
{
"name": "Home Assistant"
}
Name length: 1..80. If omitted, default is Home Assistant.
Response 201 Created:
{
"token": "gree_controller_FULL_SECRET_SHOWN_ONCE",
"item": {
"id": "uuid",
"name": "Home Assistant",
"token_prefix": "gree_controller_...",
"created_at": "..."
}
}
DELETE /api/access-tokens/{id}
Revokes token and returns 204.
Restricted Home Assistant API
These routes always require a generated token or the administrator app token.
GET /api/integrations/home-assistant/devices
Returns Device[].
POST /api/integrations/home-assistant/devices/{id}/command
Accepts DeviceCommand. A direct command is rejected if the device belongs to a disabled thermostat zone; re-enable the zone for normal HA/controller ownership or use the administrator technical device endpoint deliberately.
GET /api/integrations/home-assistant/control-plan
Same payload as administrator GET /api/control-plan.
GET /api/integrations/home-assistant/groups
Returns an HA-oriented derived group list. Each object includes:
id, name, zone_ids, zone_names,
power_enabled, effective_power,
mode, preset, house_mode,
zone_count, enabled_zones, active_zones, demanding_zones,
device_count, online_devices, current_temperature,
members[], next_events[]
Member rows include zone/device identity, configured/effective enable state, mode/preset, room/target temperature, demand, source, schedule and current manual/local ownership markers.
POST /api/integrations/home-assistant/groups/{id}/control
Same body/semantics as normal group control.
POST /api/integrations/home-assistant/house/control
Same { "mode": "cool|heat|off" } semantics as administrator house mode.
POST /api/integrations/home-assistant/house/preset
Same { "preset": "auto|comfort|sleep|away" } semantics.
POST /api/integrations/home-assistant/house/power
Same { "power": true|false } semantics.
POST /api/integrations/home-assistant/zones/{id}/control
Same ZoneControlPatch thermostat semantics as the normal zone control endpoint. The internal source is recorded as Home Assistant thermostat control.
WebSocket
Connection
Without administrator authentication:
ws://HOST:8787/ws
When GREE_CONTROLLER_APP_TOKEN is configured:
ws://HOST:8787/ws?token=APP_TOKEN
Generated restricted HA tokens are not WebSocket administrator tokens.
Message envelope
Every server event uses:
{
"event": "device.updated",
"timestamp": "2026-08-30T06:54:00Z",
"data": {}
}
The first frame is always bootstrap with the same payload as GET /api/bootstrap, unless bootstrap generation itself fails.
Common live events include:
bootstrap
device.created
device.updated
device.deleted
devices.discovered
zone.created
zone.updated
zone.deleted
group.created
group.updated
group.deleted
schedule.created
schedule.updated
schedule.deleted
schedule.template_applied
automation.created
automation.updated
automation.deleted
settings.updated
configuration.imported
debug.settings
api.request
gree.frame
log.created
Additional engine/integration events may be introduced without changing the envelope.
api.request data:
{
"method": "GET",
"path": "/api/system/info",
"status": 200,
"duration_ms": 2
}
GREE debug events are emitted only when enabled and are intended for diagnostics, not as a stable protocol API.
Localization endpoints
Language files are public so the UI can localize before administrator authentication.
GET /lang/index.json
Returns the generated catalog of embedded packs.
GET /lang/{code}.json
Returns one embedded language pack, e.g.:
GET /lang/en.json
GET /lang/pl.json

"$BASE/api/integrations/home-assistant/control-plan"
Visual Flow API
Flow is the source-of-truth representation for visual schedule/automation logic. GET /api/flows lists Flows; GET /api/flows/:id, POST /api/flows, PUT /api/flows/:id and DELETE /api/flows/:id manage them. A Flow payload contains name, enabled, optional description, nodes and edges.
Saving a Flow validates the DAG and compiles it atomically. A thermostat action driven only by one weekday block and one time-range block is emitted as a native schedule when its settings are schedule-compatible. More complex graphs are emitted as Flow-triggered automations. Generated schedules and automations expose flow_id / flow_node_id, use stable names in the form flow-<stable-unique-id>, and cannot be edited or deleted through their legacy endpoints; edit the owning Flow instead.
Condition blocks support weekday, time/date ranges, application Night mode, outdoor/device/zone temperatures, house/device/zone/group state, arbitrary Home Assistant state/numeric/attribute/availability sources, and shared_input references. Shared inputs are stored in home_assistant.flow_inputs and resolve dynamically at evaluation time. Shared inputs store reusable value sources only. They never store a comparison operator or threshold. For comparison-capable source kinds, each shared_input Flow node defines its own operator and value. PUT /api/settings rejects shared-input configs that contain an operator, and rejects comparison value fields for comparison-capable source kinds. Logic blocks support AND, OR and NOT. Action blocks target thermostat zones, GREE devices or climate groups. Direct GREE actions map to the existing DeviceCommand fields including fan, swing, quiet, turbo, light, air, xfan, health and sleep; ownership rules may suppress fields that would fight an active thermostat. Flow group actions use the existing group controller and support power, house/heat/cool mode, auto/comfort/sleep/away and the existing custom group target.
Compressor protection queue
Runtime settings expose compressor_protection_enabled and compressor_protection_seconds (30–1800; default 180). While enabled, thermostat starts and Heat/Cool reversals that fall inside the protection window are represented on the owning zone by compressor_pending_action, compressor_pending_since, and compressor_pending_until.
POST /api/zones/:id/compressor-queue/cancelcancels the currently pending compressor-protection task for one thermostat.POST /api/compressor-queue/cancel-allcancels all currently pending compressor-protection tasks.
Cancellation suppresses the same pending intent until a new explicit thermostat/group/house command re-arms it, a scheduled Temporary Quick Thermostat session takes ownership, or a different mode/target creates a new intent. Safety OFF commands are not delayed by compressor protection. Direct technical device commands remain immediate manual-control operations.
Flow portability and diagnostics
GET /api/flows/:id/export returns a versioned gree-controller-flow JSON document containing only the source graph. Generated schedules/automations are not exported.
POST /api/flows/import accepts either that envelope or a direct Flow source payload, creates a new Flow ID/revision, validates it and atomically recompiles outputs.
POST /api/flows/simulate accepts { flow, flow_id?, at?, overrides?, log? }. at is RFC3339. overrides maps Flow node IDs to simulated values. The endpoint validates and compiles the graph, evaluates every action and returns per-node traces plus matched, would_execute and blocked_reason (for example disabled zone/device, manual/local/temporary thermostat ownership, thermostat-output conflict or disabled Flow). It never mutates thermostat/device/group/schedule/automation state. Home Assistant read/attribute/parse failures evaluate safely as false and are visible in the trace instead of accidentally satisfying NOT/neq logic.
GET /api/flows/:id/logs?limit=100 returns events associated with the Flow or its generated automations.
Existing Flow updates require expected_revision. A mismatched revision returns HTTP 409 to prevent stale editor tabs from overwriting newer graphs. Source Flow plus generated outputs are replaced atomically in one database transaction while configuration/automation/schedule/thermostat-cycle operations are serialized.
Additional Flow condition blocks are house_mode, device_state, zone_state, group_state, night_mode, ha_attribute, ha_available, constant and shared_input, alongside weekday/time/date, temperature, Home Assistant state/numeric and AND/OR/NOT blocks. device_state can inspect enabled/online/power/mode/fan/swing/quiet/turbo/light/air/xfan/health/sleep state. The editor ships 37 categorized editable templates covering comfort, energy, safety, night, reliability, Home Assistant heat-source coordination and advanced multi-branch logic. The template UI adds search, favorites/recent history, a graph preview and runtime requirement checks; shared inputs expose usage links and HA-backed inputs can be tested against live entity state.
