OpenBK PowerSave 1 Command via curl on BK7231 Devices

User question

how to execute command powersave 1 on openbk with curl?

Artificial Intelligence Response

Direct answer to the question

• Use curl to hit the OpenBK HTTP command endpoint:
  • curl "http://DEVICE_IP/cm?cmnd=PowerSave%201"
• Key points:
  • Replace DEVICE_IP with your device’s IP.
  • Keep the URL in quotes and URL‑encode the space as %20 (PowerSave%201).
  • If HTTP auth is enabled, add -u user:pass.

Detailed problem analysis

• OpenBK (OpenBeken) exposes a Tasmota‑compatible HTTP interface. The /cm endpoint executes console commands passed in the cmnd query parameter.
• PowerSave 1 enables the firmware’s dynamic/light sleep. The Wi‑Fi radio naps between DTIM beacons, cutting average current while keeping TCP/MQTT connections alive. Expect a small increase in ping/HTTP latency; functionality remains normal for most uses.
• Command case is not significant (PowerSave vs powersave). Arguments are positional, so “1” after the command enables the mode.
• Typical response is JSON, e.g. {"PowerSave":1}, confirming the setting was accepted.

Current information and trends

• Recent OpenBK builds maintain Tasmota‑style /cm?cmnd= compatibility. Some builds also accept the synonym /cm?cmd=; prefer cmnd for maximum compatibility.
• Dynamic sleep (PowerSave 1) is generally recommended for BK7231‑based devices; deeper modes (if present) may trade more latency and are less universally supported.

Supporting explanations and details

• Exact commands:
  • Enable: curl "http://192.168.1.100/cm?cmnd=PowerSave%201"
  • Verify: curl "http://192.168.1.100/cm?cmnd=PowerSave"
  • Disable: curl "http://192.168.1.100/cm?cmnd=PowerSave%200"
• With authentication:
  • curl -u admin:password "http://192.168.1.100/cm?cmnd=PowerSave%201"
• Quiet, fail on HTTP errors (good for scripts):
  • curl -sSf "http://192.168.1.100/cm?cmnd=PowerSave%201"
• Alternative endpoint (if your build supports it):
  • curl "http://192.168.1.100/cm?cmd=PowerSave%201"
• POST also works (functionally equivalent here):
  • curl -X POST "http://192.168.1.100/cm?cmnd=PowerSave%201"

Ethical and legal aspects

• Do not expose the device’s HTTP interface to the public internet. If you must control it remotely, use a VPN or a secure tunnel and set a strong password.

Practical guidelines

• If you have the Web App console open in a browser, it may poll the device and temporarily reduce sleep effectiveness; close it when measuring power.
• To persist the setting across reboots, append it to autoexec.bat in LittleFS:
  • curl "http://192.168.1.100/cm?cmnd=lfs_append%20autoexec.bat%20PowerSave%201"
  • Then reboot: curl "http://192.168.1.100/cm?cmnd=restart"
• Batch across multiple devices (example bash loop):
  • for ip in 192.168.1.50 192.168.1.51; do curl -sSf "http://$ip/cm?cmnd=PowerSave%201"; done

Possible disclaimers or additional notes

• Firmware variants exist; if /cm?cmnd= fails, try /cm?cmd=. If both fail, verify firmware version and that HTTP is enabled.
• Minor Wi‑Fi latency increases are normal in PowerSave 1; if you see instability, revert with PowerSave 0 and update firmware.

Suggestions for further research

• Check your device’s Commands and FAQ documents for the exact HTTP API supported by your build.
• Review autoexec examples to standardize startup behavior (including PowerSave, MQTT, NTP, etc.).

Brief summary

• Send PowerSave 1 with: curl "http://DEVICE_IP/cm?cmnd=PowerSave%201"
• Expect a JSON ack and slightly higher latency with lower power use.
• Persist it by appending to autoexec.bat if desired, and secure the interface with a password or VPN.
