Hello Jim,

Looking for some of your oldest posts, it's clear that you are facing a problem with the RF signal since your first installation.
Those numbers only expose the problem. Your RX unit is only receiving a very small part of the data packets sent by the TX unit. Indeed, a 14% efficiency is a very low value, and doesn't assure a reliable operation of the system.

The better recommendation I can give you, is to try playing with the orientation of the antennas, both in the RX and TX units (in my case they work better in horizontal position). You can also try to find a hot spot inside your house, moving around the RX unit (or just the antenna if it have a cable) until you get a better RF signal. The TX Led (on the receiver) is a good visual sign of good reception, it should blink more or less at each 5 seconds, some times even more frequently.

I think that the metal roof is certainly your bigger problem, but I don't know.
There are on the forum some topics about the RF signal and types of antennas, please search for them, maybe you find on them some ideas. This is something you really should invest some time, without a reliable RF link, you will lost a great amount of data.

Regards

Werk,
You are right, I have been battling Rf issues for some time and am certain that the metal roof between the Tx and Rx is causing the problem. 
In the new year I intend to put an antenna in the ceiling (below the metal roof) and see how that goes. With the new display and software I can now analyse the changes.
Thanks for all your help, I really appreciate it, and I would like to wish you and your family a very merry Christmas and a happy and prosperous New Year
Kind Regards
Jim
