OneNET MQTT Credentials

Turn product and device info into an MQTT credential triplet, thing-model topics and a ready-to-paste ESP-AT command sequence.

Device

Device info → credential triplet (signed token) → an ESP-AT command sequence you can paste into a serial console. All local to your browser.

Product ID

Device ID / name

Device key (Base64)

Stays in memory for the HMAC only — never written to storage, never uploaded.

Signature method

version is fixed at 2018-10-31 by the spec.

Token expiry

Local timezone; empty means now + 30 days.

Expiry timestamp (s)

default +30 daysLocal timezone; empty means now + 30 days.

MQTT connection parameters

Fill in the device fields, then hit “Generate MQTT parameters”.

Payload & AT commands

AT commands target ESP-AT (ESP8266 / ESP32) firmware; leave time between commands for responses.

WiFi SSID

WiFi password

Property report example

Generate the MQTT parameters first — the AT commands embed the token.

Thing-model topics

Identifiers and functions depend on your OneNET product.

Fill in the device fields, then hit “Generate MQTT parameters”.

Notes

Everything runs in your browser; the device key is gone as soon as you reload.

Report length is counted in UTF-8 bytes (AT+MQTTPUBRAW wants bytes — a CJK character is 3).

AceV67og0i / humi_temp are just demo values — swap in your own.
