StromPi 3 1. INTRODUCTION Dear customer, thank you for choosing our product. In the following, we will show you what to observe during the use. If you encounter any unexpected problems during use, please do not hesitate to contact us. 2. OVERVIEW Under heavy load the StromPi 3 can heat up. Do not touch the board during operation to avoid burns. Also allow a good air supply to prevent the unit from overheating. Published: 15.10.
StromPi 3 3. POWER SOURCES The StromPi 3 can be supplied from three different power sources. In the event of a power failure, the StromPi 3 automatically switches continuously to the power source configured as secondary. MICROUSB The StromPi 3 can, as usual, be powered via a microUSB connector. WIDE-RANGE In "Wide" mode, the StromPi 3 can be operated via a voltage source in the range of 6 - 61V.
StromPi 3 BATTERY-UNIT The StromPi3 can also be extended with an optional 1000mAh LiFePO4 battery to include a rechargeable emergency power source. The separately available battery unit is simply connected to the StromPi 3 and can then be prioritized as a voltage source. With the GPIO bar in place, there are no restrictions on the use of the battery unit. 4. SERIAL CONSOLE A special innovation of the StromPi 3 is the configuration option.
StromPi 3 If you are using a 3rd generation Raspberry Pi, it is now necessary to deactivate the Bluetooth interface, otherwise the serial interface cannot be used for communication. Open the config.txt file with the following command: sudo nano /boot/config.txt Add the following line to the end of the file: dtoverlay=pi3-miniuart-bt enable_uart=1 core_freq=250 Save the file with the key combination Ctrl+O and exit the file with the combination Ctrl+X. Published: 15.10.
StromPi 3 In addition, it is necessary to activate the serial interface of the Raspberry Pis and to deactivate the serial console. You can do this either via the Raspberry Pi Configuration or via the Raspi -Config. To do this via the Raspi-Config, enter the following command in a terminal window on your Raspberry Pi: sudo raspi-config Use the arrow keys on your keyboard to navigate to the " 5 Interfacing Options" menu item. Select "P6 Serial" here. Published: 15.10.
StromPi 3 Answer the question "Would you like a login shell to be accessible over serial? “ with „No“. Answer the question "Would you like the serial port hardware to be enabled? “ with „Yes“. After a new confirmation you can leave the menu with " Finish". Answer the question about restarting the device with " Yes". The serial port is now enabled and the serial console is disabled. Published: 15.10.
StromPi 3 OPENING THE SERIAL CONSOLE OF THE STROMPI 3 You can open the StromPi 3 console with the following command: sudo screen /dev/serial0 38400 Attention! The system now waits for another entry and may not display your next keystrokes. Enter the following command and confirm it with Enter, even if you may not see your entry: startstrompiconsole The serial console of the StromPi 3 opens. You can view the current configuration setting of your device with the show-status command.
StromPi 3 5. INPUT PRIORITIZATION The voltage source from which the StromPi 3 draws its energy can be set according to your wishes and application. In addition, a second power source can be selected, which automatically takes over the supply in case the first source fails. The factory setting is configured to use the microUSB input as the main power source. If this fails, the wide-range input is automatically switched on as an alternative source. A total of four different modes are available.
StromPi 3 6. TIME-CONTROLLED APPLICATIONS The StromPi 3 also has a real-time clock. If the power fails, even time-controlled applications are not endangered. Time controlled startup and shutdown of the Raspberry Pis are also no problem! 6.
StromPi 3 AUTOMATIC TIME-CONFIGURATION The StromPi 3 is also capable of automatically detecting and correcting incorrect time configurations. This is done by a separate script, which must be active in the background. With this script, if the times of the Raspberry Pis and the StromPi 3 differ from each other, it is assumed that the more current of the two times is the correct time. In this case, the older time is automatically adjusted to the newer time. You can download the time update script here.
StromPi 3 Here you can add the script to the autostart. The following command must be inserted before the "exit 0" command. python /home/pi/RTCSerial.py & If you have not copied the script into the folder " /home/pi", you have to adjust the path accordingly. Save the file with the key combination CTRL+O, confirm with Enter and exit the editor with the combination CTRL+X. The changes take effect after a restart. Published: 15.10.
StromPi 3 6.2 SHUT-DOWN TIMER & POWER-OFF ALARM Attention! For the automatic shutdown and startup an additional script is necessary, which receives and processes the shutdown signal of the StromPis. You can download the script here. Download the archive, extract the script and copy it to your Raspberry Pi. The script can be copied into the autostart of your Raspberry Pis as follows: sudo nano /etc/rc.local Here you can add the script to the autostart.
StromPi 3 SHUTDOWN-TIMER The StromPi 3 has a shutdown timer that automatically shuts down your Raspberry Pi after a primary power failure is detected.You can individually adjust the time span when the shutdown takes place after the power supply fails to suit your needs.
StromPi 3 POWER-OFF-ALARM The StromPi 3 can shut down your Raspberry Pi time -controlled. To configure a time you can use the following command: poweroff-set-time Attention! Only use two-digit numbers for the time entries (for example 05 15 for 05:15 AM). You can activate or deactivate the power -off alarm with this command: poweroff-enable
StromPi 3 6.3 ALARM-MODE The StromPi 3 can automatically start your Raspberry Pi at certain times. The following modes are available: Mode 1 Daily time alarm Mode 2 Date controlled time alarm Mode 3 Weekly time alarm To configure the alarm mode, use the following command: alarm-mode The alarm can be activated with this command: alarm-enable
StromPi 3 The following commands can be used to configure the alarm time: Configuration of the alarm time: alarm set-time Attention! Use only two-digit numbers for entering hours and minutes. Configuration of the alarm weekday: alarm-set-weekday The day of the week is the numeric day of the week: 1: 2: 3: 4: 5: 6: 7: Monday Tuesday Wednesday Thursday Friday Saturday Sunday Attention! When entering commands, make sure that they are entered correctly.
StromPi 3 Configuration of the date alarm: alarm-set-date Attention! Only use two-digit numbers to specify the day and month (for example: 01 01 for January 1). The alarm mode and the power-off alarm can of course be combined with each other. You can configure an individual start -stop behavior for your Raspberry Pi (e.g. boot up every Monday at 16:00 and shut down every Wednesday at 11:00).
StromPi 3 EXAMPLE OF PRACTICAL APPLICATION The Raspberry Pi is to be launched daily at 10:00 AM for the opening of a store. An image is to be automatically displayed on a separate monitor for advertising purposes. The Raspberry Pi should shut down punctually, at 6 PM. at the close of business, as it is not needed after closing time.
