Water (leakage) sensor on supply 230V

Hi.

Is there a water floor sensor that runs on power supply not batteries out there for Homey?

I think most devices are designed to work independently.
Think of a leakage causes by an power outage for outgoing pumps. Then a 220V senser would not help (at least locally with sound).

Also, water and 220V don’t mix very well.

I know of two water leakage sensors that can be operated with a power supply but also have an backup battery:

Or you take a sensor with battery, and use a power supply with battery adapter, something like that…

But you have to find out that battery adapter are available for the type of battery of the sensor
