Rate limits

Through api.igh.app and MCP, per home (the gateway's cloud account):

Limit	Value
Requests	50 a second and 600 a minute (WebSocket messages included)
WebSocket connections	20 at a time
Accept agent requests	5 a minute, 30 an hour
Request body	16 KiB

Over a limit the answer is 429 rate_limited with retryAfter (seconds) in the body and a Retry-After header: wait that long. On the home network there are no rate limits, but the units themselves are slow: don't send more than a few commands a second to one unit.

Examples

(Too many requests through the cloud in one second.)

GET /v1/state

Answer 429:

{
  "error": {
    "code": "rate_limited",
    "message": "Too many requests for this home. Wait and try again.",
    "retryAfter": 1
  }
}
