Configuring ID in HA for Homeeasy devices from RFXtrx, Lighting 2

Hi!
I just moved from Domoticz to HA, and struggle to get all my Homeeasy devices to work.
I have several wall mounted switches/dimmers, they are just receivers so won’t be found by auto detect.
I have all ID and unit info, but don’t know how to add to HA.
There is an ID generator for Lighting 1 and 5 codes, but the majority of my devices are Lighting 2.
Anyone able to help?
