Battery status for window sensor LDHD2AZW by Leedarson

These are used by Xfinity for their home security system. They are standard zigbee devices and work great, especially for their retail price of $9. However, I need advice on how to get the battery status to quit reporting “unknown”.
Anyone out there that has a solution for me?

(oh yeah, I’m controlling my zigbee network with Home Automation’s Zigbee integration on a Conbee II stick hanging out of my pi3b+)

Same Question. Any Ideas?
