Troubleshooting

By default, the Pekaway image for Raspberry Pi has an access point open that you can connect to via WiFi. The SSID is "PeKaWayControl_xxx" and the default password is "pekawayfetzt". Please make sure that you are connected to this access point.

Enter the full URL into the address bar of your browser, including "http://". If that doesn't work, you can access the system at " http://192.168.4.1:1880/ui" .

If the Raspberry Pi is integrated into an existing network, the system can be accessed under "<RPI-IP>:1880/ui"

Find the IP address of the Raspberry to reach the system at "<RPI-IP>:1880/ui". To find out the address, log into your router, or start an IP scan using e.g. Angry IP Scanner (Linux, Windows & MacOS) .

Alternatively, the system can be accessed at " http://pekaway.local"

Is the operating voltage of 12v present? Is the ground cable connected correctly.

Is the SD card possibly damaged?

Is the Raspberry or the Hat plugged in correctly?

Was the system connected to another WiFi or is the system connected to your home network?

If nothing is responding, you can simply download our current image and reload your SD card. We recommend Balena Etcher or Win32Disk manager. You can find the image in the downloads.

Did something go wrong with the calibration of the sensors? You can reset the values ​​in the web interface.

If you use resistance sensors, you can measure the resistance values ​​with a multimeter and check whether they are correct. If these values ​​differ from the specified values, you should use the measured ones.

If you use our preset for Votronic tank sensors, you must set the maximum voltage of the sensors to 2.4V using the adjusting screw.

- Check if the jumper section on the relay board is set for the correct sensor type (resistive or capacitive).

- Check the analog-digital converter, in the web interface Config->Debug you will find the I2C scan. The value 48 should be displayed there, among other things. If this is not the case, your ADC has been damaged by an overvoltage at the signal inputs. (MAX 3V) If this is not the case, please contact support. We offer a repair.

- In the web interface you will also find a function to display the analog values ​​of the inputs. This allows you to see the values ​​before the actual calibration. NOTE: The values ​​are only updated every 15 seconds.

- Check your wiring, use wire sleeves if possible

- Check the pull-up resistor between signal and 3.3V on the temperature plug, this should be between 5KOhm - 10KOhm. It can be adjusted using the potentiometer above the connection terminal. Long cable runs can also be adjusted using the potentiometer. A classic trail and error principle is recommended here.

- Test the DS18B20 on another device, there are many fake sensors, often they are not waterproof and cause problems due to moisture.

Check whether the "Inside Temp" sensor is set in the web interface -> Config -> Sensors. This tells you which temperature sensor should be used. This sensor is also used for heating control

Is the touch display connected via a patch network cable? Older, no longer common cross-over cables are not supported.

Is the network cable defective?

Are both the display and the Raspberry Pi running the latest software? Different versions can cause problems.

Is there a button cell on the back of the display? This is needed for the watch.

Is the clock on the display set correctly?

An incorrect time on the display can also lead to an incorrect time in the system and thus affect the timer function. The monitor function will then also no longer function fully.

If you set the names via the web interface, the display on the respective page must be switched on or active. As soon as you press Update in the web interface, the names are also sent to the display.

Make sure to set the MainBatt Data in the web interface Config->System. The data will now be sent from the correct location to the touch display.

Bridge switches (DIP switches) may be pressed. These overwrite the switching value from the system. This allows relays to be switched manually or permanently for development purposes. For example, if you make adjustments or tests in the Node-RED backend but don't want your light relay to be switched, you can simply bridge it.

Is the Victron device switched on?

Is the correct port set to Ve.Direct in the config?

Have you restarted your system yet?

Please always remember that all work should be checked by qualified personnel.

If your cables get very hot, you haven't dimensioned them correctly. Please take a look at our 1x1, where you will find help.

It is always important to protect everything according to the cable cross-section - OTHERWISE IT COULD CAUSE A FIRE!

Please remember to disconnect the battery from your smartphone before you start using the system. Otherwise, the respective app may block access to the VAN PI system. If you have not used the app for a while, it may be that your battery has been detected as unavailable. The battery is deactivated to save power. However, it checks at longer intervals to see if the battery is accessible again. If this takes too long, you can simply reset the battery in the web interface.

Is the VAN PI shunt activated in the config?

Is the wiring correct?

Was the shunt connected incorrectly? -> this can lead to damage.

If there is a voltage deviation, you can report this via the
Calibrate the web interface. To do this, measure the voltage with a
Multimeter and enter it in the "Calibrate VOLTS" field.

The shunt counts the watt hours consumed and charged by the battery. If this is not configured correctly or the SOC is incorrectly initialized, the shunt may show a value in the negative range. We have allowed this on purpose to enable better settings.

For example, a smaller set capacity leads to a "minus buffer".

Please check the MainBatt setting in the web interface ->Config->System. The shunt must be selected here.

The FUSY has a circuit that activates an LED when the fuse fails. This parallel circuit ensures that a voltage can always be measured at the output. However, as soon as a consumer is connected, this voltage immediately collapses, as only minimal currents are possible here. The LED also only lights up when a consumer is connected to the respective circuit and the circuit is therefore closed.

Please make sure you use high-quality cables that are actually 4mm².

It is also important not to twist the cable, but rather just strip it and then insert it straight. The Wago terminals have guides to bring the cable together at the end. If you twist it, it will become wider and cannot be inserted completely.

Please remember that the circuit must be closed for the LED to light up.

A consumer must therefore be connected to the respective circuit.

If no consumer is connected and the circuit is therefore open, the LED cannot light up.

- Please check if your laptop supports the PD3.0 charging standard.

- Use a cable with an E-Maker chip, which is required to transmit 100W. For example, you can use our original Pekaway cable.

- Do you have a sufficient power supply? Remember that your 12V/24V supply must also be able to deliver 100W.
