I had an exhausting day so I will be brief. They are both reporting now so I will start experimenting with them over the next couple of days. I am sure I will have lots of questions. I think what solved the problem was waking up the sensors immediately after changing the device type but I am not sure. I know almost nothing about adding Custom DTHs. I see you also have a DTH for the Dome Siren. I might purchase one of these later.
Thanks very much for your help,
