I see it sense current, but there's no voltage sensing capability (unless I'm missing something).

You're not missing anything. But a few photographs of the setup would be very helpful to recommend a solution.

For example, if you can find a 200-240V step-down transformer to 5VAC, then a device like this would work:

@tony3286 Here's a list of parts that you will need to build one: USB power supply USB power cord 5VDC relay A zigbee/z-wave contact sensor with external contacts (I use a GoControl WADWAZ-1 - $7 on eBay). A project box to put the relay and contact sensor in Takes about 15 minutes to build. Here's what my finished sensor looks like: [IMG_20200105_000546] [IMG_20200105_000533] [IMG_20200105_000640]
