Water level

Hi all,

I need to monitor the water in a tank, and get a notification when is above a certain level. The tank must be always empty (in reality is not a tank, but the windows of my basement ) and I need a notification when too much water is in inside it.
Which is the best solution? Shelly 1? Any external wire needed?

Thanks

To be more precise, I do not need the water level, but an on/off signal which is triggered when the water is too high

Would this one work with a Shelly 1 Plus?

Or maybe using the Shelly Addon connected to a Shelly Pkus and then a sensor which closes the contact when hit by water?
The question is if the Shelly addon is supported by the Shelly plugin

I use a float sensor connected to one of the X10 IO plugin units to monitor the drain pan under my main AC unit.

Ok float sensor came also to my mind, but I have z wave or zigbee available, no X10

Can you use a water sensor such as:

HomeSeer HS-LS100+ Z-Wave Plus Leak Sensor.

It comes with a cable and probe.

But I think that it will last that long outdoor

More than likely, the float is a simple switch, so any I/O input that works with switches should work.

Yes then why not connect the floating sensor to a Shelly 1 Plus which is basically an open contact (no potential) which gets closed when the floating sensor is triggered?

Precisely.

My only gig on the Shelly is that it's WiFi and not Z-Wave, but it should be fine with one of the Shelly plugins.

Yes, exactly, I bought one of those floating sensor, I will connect it to the SW pin of the Shelly and I am done
