Example

# → 956432  (i.e. 956.4 KH/s)

POST /api/system/restart

Reboots the miner immediately.

Request

No body.

Response

{ "status": "ok" }

The reboot happens ~600 ms after the response is sent so the connection closes cleanly.

Example

curl -X POST http://192.168.1.42/api/system/restart

warning

A restart drops the Stratum session and any unsubmitted shares. Avoid scripting periodic restarts unless you really need to.
