Control power to battery-powered house number signs

Hmm. But what about those solar-powered lights (given as example)?

This is listed for 8-10 hour runtime when charged, and I’m really only looking to power it selectively, anyway. Would there be no way of controlling power distribution - have the panels charge the battery during the day, but not power the lights until/unless [the ST-compatible something that I’m asking about] allows it?

Robin mentions that battery powered smart device (e.g. contact switch?) pings every few seconds. I’m not sure how that’s a limitation, that seems like a perfect use case…? What am I missing?
