Create a MQTT topic to "reset to factory defaults" #12

Closed johnwalicki closed 3 years ago

The dashboard will implement a "Remove your sensor from the OpenEEW network" button. It promises that your sensor will no longer contribute data.

The dashboard could delete the Cloudant record which would wipe the uuid ownership / latitude / longitude / what regional network it belongs to.
That would not stop the device from sending data however.... The device doesn't know - its stateless.
The dashboard could send the MQTT command to turn off the ADXL accelerometer so it doesn't record/send data. When the device restarts, It will start sending data again.
Create a MQTT topic to "reset to factory defaults" - It would remove all WiFi SSID/password from NVM ram. That would force the device into SmartConfig Provisioning mode.

Todos:

[x] Test the feature by sending remote MQTT topic to the OpenEEW sensor
[x] Update the Node-RED device orchestration dashboard
[x] Push the container to device-mgmt.openeew.com
[x] Update the firmware.md to show examples of the factoryreset topic.

The topic will be iot-2/cmd/factoryreset/fmt/json There will be no stringified json key/value pair passed as part of this topic. {}

Once the device is in SmartConfig Provisioning mode, the mobile app can be used to connect it to a different WiFi network and register it again (potentially under a different email address / user)

In addition to clearing the NVM of WiFi networks, a Factory Reset implies a restart. The device will clear NVM, restart, boot to SmartConfig.
