How can I capture and submit IR codes for missing remotes?

[ponchohoncho]

I have a handful of remotes that are not in your database, one in particular that I've seen requests for and is very very expensive and hard to find. I really want to scan these in to help other people who are looking for these remotes. I have an ESP32 running ESPHome with an IR receiver, and looking the logs as I press buttons on this remote, I get codes like this:

but other remotes give me results like this

I'm more than happy to press buttons and submit readings all day, but I don't know how to get these into a format that's helpful for other people,

I would recommend that you use IrScrutinizer, together with some suitable, supported hardware for capturing. If want to use your ESP32 you can flash AGirs (also found in the Arduino library manager) onto it. Then use the "Scrutinize remote" pane capture the interesting signals, and entering their text names. After capturing, you export using the export format "IRDB CSV", that generate a CVS file that can be used here.

If anything is unclear, just ask.

I second this. IrScrutinizer is your swiss army knife for all things infrared.

Thank you for the suggestion, I will look into it! Do the raw readings from ESPHome not work for this purpose?

Do the raw readings from ESPHome not work for this purpose?

For example, you can cut-n-paste the raw codes into the "Scrutinize remote" to have them decoded, and then enter the decode into the parametric remote table. However, this is inconvenient and error prone. If you have a large number or commands to capture, you certainly would take advantage of a hardware that IrScrutinizer can talk to directly. Consider building a dedicated device, like this.

If you already have long lists of captures in raw format, these can be tweaked with a text editor or a script to be in a format that can be imported into IrScrutinizer.
