Battery status not working
<!-- You must use the issue template below. -->
<!-- Please ensure you read the documentation before creating a support request. -->

**Describe The Problem:**
I just updated to the latest plug-in after updating Node.JS, and now the battery status no longer works. The accessories page says "null%" for the battery, and the Home app shows no battery status for my door sensor. 

**To Reproduce:**
Update Node.JS and update plug-in to latest version. Check accessories page and see battery percentage not being displayed. 

**Logs:**
<!-- In order to be helpful, include the relevant logs from Homebridge, if applicable. -->
Nothing really in the logs. It says battery status support is enabled.
