Blank Dashboard Issues

[adelong1431]

I purchased a Raspberry Pi 4B 64bit with noobs pre-installed. I followed https://github.com/tagyoureit/nodejs-poolController/wiki#:~:text=Raspberry%20Pi%20Setup%20(by%20gw8674) to set up my Raspberry Pi with both the poolController, and the dashPanel. After I completed the guide, I am receiving a blank dashboard.

The following things are standing out to me as different in my install, and CLI differences. I'm looking for some help on next steps if you can provide guidance.

• This Pi is 64 bit, and the guide says to set up as 32 bit
• When I execute step 5C I receive 2 lines: >nodejs-poolcontroller@10.0.1 prestart >node -e "const v=process.versions.node.split('.').map(Number);if(v[0]<22){console.error('\x1b{31mError: Node.js >=22 required (found '+process.version+').\x1b{0m');process.exit(1)}" (picture provided
• I never receive the "Configuration Complete" CLI line in step 5C (picture provided)
• Nixie controller is initializing even though an easytouch has been found (picture provided)
• dash panel only contains "lights" (picture provided)

This is my first time ever using a RPi, and based on forum searches, I'm pretty positive I'm missing something obvious.

Not sure if this will help.

Node version needs updated for current version

[hubuser01]

I believe nodejs-poolController version 10 needs a newer node version than 20.
This is my node version:
node -v
v24.18.0

change
nvm install 20
to
nvm install 24

getting more errors. tried searching google... tried running the "nvm use --delete-prefix v24.21.0 to unset it with no luck.

What does this command show?
ls $NVM_DIR/versions/node

check this link:
https://stackoverflow.com/questions/34718528/nvm-is-not-compatible-with-the-npm-config-prefix-option
follow the answer with 500+ upvotes. Make sure to change the version to 24.21.0
npm config set prefix $NVM_DIR/versions/node/v24.21.0

Those commands did not work either. I ended up formatting my SD card back to a stock Raspberry Pi 4 64 bit image, and started over.

I replaced the nvm install with the following line from the nvm github:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.8/install.sh | bash

After this nvm install 24 worked perfectly.

The root cause of my problem is that neither the quickstart guide or the raspberry pi setup guide explicitly said that i need to open ANOTHER terminal for the dashboard.

After executing npm start& in the nodejs-poolController directory, you need to open ANOTHER terminal and execute npm start& in the nodejs-poolController-dashPanel directory.

My pool controller is now working as expected but im still getting the:

nodejs-poolcontroller@10.0.1 prestart >node -e "const v=process.versions.node.split('.').map(Number);if(v[0]<22){console.error('\x1b{31mError: Node.js >=22 required (found '+process.version+').\x1b{0m');process.exit(1)}

error even though when i run node -v it returns v24.21.0.

Could it be that my npm is returning 11.19.0?

How do i help update the quick start guide? I'm willing to add some additional details, and add latest versions to help the community out.

Im glad you figured it out.

If you also use relayEquipmentManager, then you would need to open a third terminal.
The Auto-start at boot (PM2 & Systemd) section would start all processes upon boot and there would be no need to start any terminals.

Not sure of the error. It looks to be checking the running version of node. if node version < 22 then report error, show version and exit. Anything else it should continue executing. Not sure this is an actual error. It just might be information.
