SimpliSafe sensors battery state

Has anyone looked into the Simplisafe system battery sensors?
Does Simplisafe not share the battery states for all the sensors or am I missing something in the integration?
I have a lot of sensors and wanted to use the battery-state-card to track them all, monitor state, and notify when some are almost empty.

Any thoughts?

I’m wondering if you, or anyone else, found a way to get battery state. I have an alert that notifies me of low batteries and would like to include Simplisafe batteries. Thanks
