System Commands

antiburn~

accepted parameters: on/off, true/false, 0/1, yes/no

Start LCD anti burn-in protection.

This cycles the display to a full black, red, green, blue and white color each second to relief the tension put on each individual pixel. The cycle stops when either:

  • 30 seconds have passed
  • antiburn=off is received
  • The screen is touched

If you're using Home Assistant, check out the [automation example][6] to make it run on a regular basis.

calibrate~

Start on-screen touch calibration.

You need to issue a soft reboot command to save the new calibration settings. If you do a hard reset of the device, the calibration settings will be lost.

discovery~

Trigger the sending of the discovery payload.

sensors ~

Trigger the sending of the sensor data.

factoryreset~

Clear the filesystem and EEPROM and reboot the device in its initial state.

Warning

There is no confirmation prompt nor an undo function!

reboot or restart~

Saves any changes in the configuration file and reboots the device.

screenshot~

Saves a picture of the current screen to the flash filesystem. You can retrieve it via http://<ip-address>/screenshot.bmp. This can be handy for bug reporting or documentation.

The previous screenshot is overwritten.

service~

Start or stop some of the processes running on the plate.

Currently supported parameters:

  • start
  • stop

Currently supported services:

  • http (web interface)
  • telnet (remote console)
  • console (serial console)

Example

To stop the web interface of the plate, send to topic hasp/<your_plate>/command/service the string stop http. To start the web interface of the plate, send to topic hasp/<your_plate>/command/service the string start http.

Tip

Once these services are stopped, connection is lost/not possible to the plate through them. They can be started at any time by sending service start commands in through MQTT.
It's possible to create self-built firmware binaries which have services stopped by default at boot, using customization.

statusupdate~

Reports the status of the MCU. The response will be posted to the state topic.

}

unzip~

Unzip a file-packgage on the plate. You can upload uncompressed ZIP files to the flash space of your plate and unzip them locally. This is useful for cases when you need a lot of small files to be uploaded - putting them in an uncompressed zip allows to upload them in one go, and then extract them with a single command:

Example

unzip /openhasp-weathericons-day.zip

update~

accepted parameters: [url]
Update the firmware from the url provided. Reboots when update was successful.
