Running for months without thinking about power

After setting everything up, this timer has basically been running in the background for months now.

What I didn’t expect is how little attention it needs over time. Even after extended use, power consumption hasn’t been something I’ve had to think about at all.

There’s no constant checking, no adjustments, just steady background operation while everything else goes on normally.

Has anyone else used outdoor systems that can just run long-term like this without becoming a concern?
