Testers Needed! I built an app that connects to your Hopoocolor meter and uploads directly to hCRI.io

Some of you know I built hCRI.io, the free tool for checking CRI/TM-30/CCT/Duv etc. from a spectral measurement.

I made an Android app to go with it. If you’ve got a Hopoocolor HPCS-series meter, it will:

  • Connect to the meter over Bluetooth

  • Pull the spectrum straight off the sensor

  • Upload it to your hCRI.io account in one tap

No more pulling a CSV off and uploading by hand.

One thing that’s different from the stock Hopoocolor app: everything in my app is computed from the raw wavelength/intensity spectrum, the same way hCRI.io does it on the website, instead of trusting the numbers the meter itself spits out. The onboard CCT/Ra/etc. the stock app shows comes from the meter’s own firmware, and that can drift or vary a bit between firmware versions. Working straight off the spectrum means what you see in my app matches what hCRI.io shows once you upload it, one consistent set of numbers instead of two slightly different ones.

It’s currently in closed testing, not on the Play Store yet, and Android only for now. An iOS version is on the list once I pay to join the Apple developer program.

If you want in on testing:

  • Email fizzgig@hcri.io and I’ll add you as a tester, or

  • Reply or DM me here on BLF

Happy to answer questions on either the app or hCRI.io in general.

Do you know if this will work with Bluestacks on the PC? I’m 99% sure my Hopoocolor doesn’t have bluetooth.

Which hopoocolor do you have? Right now this supports the following models

310, 310p, 330, 330p, 330 pro

I have the 320.

This won’t support that. And right now it only supports the listed meters.

Ill be working on a setup for torch bearer and ColorMunki that will use an interface device. Bit that won’t be for a while

Is there some sort of open “API” documentation i can use to automatically send data to hCRI.io
Because i want to make a “app” or program like this to automatically publish my measurements to the site.

But i want to use a different spectrometer and not the Hopoocolor.

Ideally i would like to have a workflow where i can just press a button and get the nice hCRI.io style previw of the datat.
from there add a view infos,tags, meta data. and then publish it to your database.

And an additional idea for hCRI.io maybe add fild or tag for License?
Because even tough i can Download the measurement data from the side it not clear to me how im allowed to uses it.

The api details are in your profile where you create a token. As for usage, that’s all in the website terms and conditions. Basically the data is owned by the users who are free to delete or make it private.

There also isn’t a way to download data from the site. That’s intentional.

Which spectrometer do you use?

Which spectrometer do you use?
x rite i1.
at the moment with Argyllcms but i plan to replace this soon

You can download individual data sets but not all of them via an api. And all they are is wavelength data sets.
