Yes. The transmitter works from the RFToy using the codes that I recorded with it.
I input these codes as names into stations. I have tried both low number stations and high number stations.
I connect the the transmitter’s data to GPIO18, set RF Data to 18 in Defines, save, recompile and reboot . Fail.
Repeat the above except move the data connection to GPIO15, setting rf data in defines to 15. Fail, with an added buzz from the relay.
Updated the firmware from 2.1.3 to 2.1.4, retested. Fail.
Move the transmitter back to the RFToy and it still works.
