How to send Z-wave packet to battery powered device

I am currently using SendData to set command packets (climate control schedule) to a battery powered Danfoss Living Connect

This works when I have pressed buttons on the LC as it is awake at this time. If I don’t wake the device up manually then the
SendData action fails as the device has its radio off, as you would expect with a battery powered device.

I see that when I change setpoints using the existing thermostat support there’s an attempt to send the Z-Wave packet 5 times
after which time a retry is scheduled for when the node wakes up.

 ZWJob_SendData::ReceivedFrame job job#36 :Heat SP 24 node 4 (0x963cd8) N:4 P:70 S:5 to node 4 command 67/1 failed m_cTxStatus 1 retries 5 <0x803>
01      12/10/11 12:20:51.094   ZWJob_SendData::JobFailed job#36 :Heat SP 24 node 4 (0x963cd8) N:4 P:70 S:5 Priority 70 <0x803>
04      12/10/11 12:20:51.096   <Job ID="36" Name="Heat SP 24 node 4" Device="5" Created="11-12-10 12:20:49" Started="11-12-10 12:20:49" Completed="11-12-10 12:20:51" Duration="1.135450000" Runtime="1.129431000" Status="Aborted" LastNote="Failed, waiting to retry when the node wakes up" Node="4" NodeType="ZWaveThermostat" NodeDescription="Horstmann Thermostat"/> <0x803>

I need to understand how to achieve this in Luup. Any thoughts?

Thanks, Alex
