Battery condition for a repeater

Brian, I have just purchased a 433mhz Repeater - RT918. It is a wireless repeater that extends the range of most Oregon Scientific 433mhz sensors by up to 100 meters. Each repeater will support any one of 7 remote sensor types. Has transmit and low battery indication. Indoor / outdoor use

As I have relocated my solar sensor to the front of the house, I have a need for this as the signal as it is will not go through or around the house. Therefore, 2 questions. 1) Is there a way you can include the remote sensor battery condition into the WMR918 part of the WD program. 2) Will I still be able to receive the battery condition status of the solar sensor - because the data is now going through the repeater.
