This is the JP1 beginners forum. There's no such thing as a stupid question in here, so post away, but this forum is just for JP1 users and people considering JP1, non-JP1 users please use the appropriate forum above!
We have RDF files for the URC7145 (2018) and URC7145 R02 (2021). So clearly these are programmable with JP1. If you get a 7125 or 7135, we may need to make a small revision to the RDF, but I'm confident these will also be programmable.
