Questions and answers

Why does the device return to setup mode?

PressureMon starts its setup access point when it needs configuration, when measurement sensors are disabled, or when the configured battery voltage is outside the accepted range. Check the battery and sensor settings, then reconnect to the device access point. The default access point password is password and the setup page is at 192.168.4.1.

Why is Bluetooth missing?

Bluetooth is available on the ESP32-S3 and ESP32-C3 builds. The ESP32-S2 Mini does not provide BLE support in this firmware.

Can I connect two pressure sensors?

Some supported boards expose a second I2C bus for an optional second sensor. Check the board table in Hardware; availability and bus implementation differ by target.

How do I restore the device after changing Wi-Fi settings?

Use the device setup access point and configure Wi-Fi again. If necessary, force configuration mode from the Home page or restart the device while its configuration condition is present.

How do I update firmware?

Use the PressureMon flasher linked from the GravityMon website. Select the build for the exact board and follow the instructions shown by the flasher. The web interface also supports OTA updates when the device is already reachable on the network.
