[Is there a way we can record IR inputs and submit them to your database?]

Of course I can share the files I created. I have an Haier TV that I couldn't control with the existing profiles (could be my mistake) and a Topping DX3Pro DAC for my audio. For anyone interested in the Topping codes, those should work for all Topping devices.

About simple text importing, I first created a .txt file with the syntax detailed in your linked post but on the Windows app, I couldn't import anything else than files with a .json extension. For this reason, i tried to mimic a json file already present on the Brands tab.

Haier - LDF40V280S.json Topping - DX3Pro.json

[Is there a way we can record IR inputs and submit them to your database?]

I successfully imported two devices that are not in the database following your procedure, thanks!

I got the raw IR timings for each button using a Flirc USB dongle and the Flirc app in IR debugging mode. I pasted the raw codes (without the first "0," string) into irscrutinizer using the button "Paste & Scrutinize" to convert them into PRONTO codes. With the PRONTO code for each button of the remote, I built a json file with the same structure as the files in the admin tab of the Skip App under Brands. Once done for a device or a remote, I was finally able to import this json file to the app by clicking Add on the admin tab.

One could probably build a community app using flirc_util and the irgen python module to speed up the procedure.
