Guide 2
Set up and flash a gateway.
Gateway setup turns a profile into a running edge app. You choose the profile, select telemetry values, enter site access details, and flash the ESP32 from the browser.
Choose the right profile
The profile picker narrows a large library into a small choice. Start with who owns the profile, then type, then the exact model.
Pick Built-In or Your ProfilesBuilt-In profiles are maintained by MojoScale. Your Profiles are profiles you created or cloned.
Pick the device typeExamples are genset, meter, pump, motor, sensor, or custom.
Search and select the profileSearch by name, vendor, model, or type. When selected, the setup page copies the profile defaults.

Select metrics
Many profiles have 50 to 150 possible values. The gateway should not send all of them continuously. Select the values that matter operationally.
Telemetry ValuesPick up to 16 continuous values. Example: battery voltage, RPM, frequency, power, current, pressure, temperature.
Status, Enum, TextThese are included automatically where useful because they describe machine state and do not behave like high-rate numeric telemetry.
AlarmsAlarm and fault definitions are included automatically. Users should not have to spend metric slots on alarms that only appear occasionally.

Gateway, webserver, AP, and Wi-Fi fields
These fields decide how the installed gateway identifies itself, connects to the site network, and remains accessible locally.
Gateway NameThe visible name in MojoScale. Use a site-specific name like north-yard-meter or shop-genset-1.
Local Web AddressThe `.local` address users can try on the same network, for example north-yard-meter.local.
AP SSID and PasswordThe fallback Wi-Fi network created by the gateway if normal Wi-Fi is unavailable. The user can connect to it and open 192.168.4.1.
Wi-Fi CredentialsThe site network the gateway should join after boot.
Webserver LoginLocal username/password for the gateway web page.
