Sorry to dig up old thread.
I also have an OSBo and would like to make use of the mini-relay.
I have recently upgraded to Firmware 2.1.9(9).
@nystrom – were you able to get the mini-relay working? If so, what changes did you have to make?
@Ray – I know you said the mini-relay has been discontinued, but it would be great if it was still useable for those that have it. Can you provide pointers on what changes we can make ourselves to use the mini-relay?
