Just remember if you upload a config which isn't working doesn't prove the config is OK but you will soon find out if you have a unit to swap.
After unit swap, second DLT has firmware 3.0. Initial version was 2.0
DLT operational logic is now restored. So I have concluded it was a firmware bug / generic failure / loss of connectivity to incoming data.
Interesting fact was that it took me 3 attempts to erase all of the button labels. That may prove consistent with my issue. It will make a good light switch despite the technical issues. I wont use the first module for data logic.
Now the question is, can I send my DLT for refurbishment back to clipsal and pay a modest fee. Or does anyone know how to flash the firmware ?
