IR signal resources on the Internet — an annotated collection

Revision history
Date Description
2016-04-29 Initial version.


This page collects a number or Internet resources, that I have found usable for myself. There is an emphasis on free and open source resources. It is not by any means attempts to be an exhaustive list. Nevertheless, suggestions for additional entries are welcome.

The different services below may impose their own rules and conditions for their usage. It is the responsibility of the reader to observe these.
The correctness of the data cannot be guaranteed. Sometimes the data is incomplete, unparseable, or outright wrong. Sending undocumented IR signals to your equipment may put it in an unwanted state, or even damage it, possibly even irrevocably. By using this information, you agree to take the responsibility for possible damages yourself, and not to hold the author responsible.

With the exception of GirrLib, I am not connected with any of the sources below. However, I sometimes participate in the JP1 and RemoteCentral forums, and on the Lirc mailing list.
