Hello,

yes, that works and you're in luck, because now with OSPi version 1.5 there are two sensor inputs - 1.44 and its predecessor only had one.

You need a relay with suitable power, I don't know the power of the submersible pump, so check whether the following relay fits:

Finder 22.32.0.024.4540 Contactor 1 make contact, 1 break contact

Your float switch works like a rain sensor when it rains -> no watering. So if Sen1 and GND are connected, the submersible pump is not activated.

You can set for each circuit whether it should react to Sen1.
