which Shelly device most suited to control Water Pump? Shelly 2.5???

Hi there, I'm new to the Shelly world and so far only found wiring diagrams for lighting circuits using the shelly relays. I have a 230v pump currently operating via a 16amp MCB and activates via automatic switching using floats at a spring and a solenoid. However, I currently have to turn the MCB off and on when desired as the pump is being used to either fill a tank or water the garden via sprinklers and sometimes I am able to pump water from my river. My preference will be to simply turn the pump on and off via the app, or program it to come on at certain times as the weather changes. My house WIFI reaches the shed where the power and the pump is situated, so the question is which device or relay would be most suited for this system? From browsing threads and other sites I am thinking the shelly 2.5? Thanks in advance to whoever has reads this

I'm using a Plus2PM setup with a script to reset an MCB, its slightly more complex as mine uses a light sensor to determine if a device has crashed. However either way what you need is a 16A contactor, wire the contactor to the Shelly and treat it as a big relay.

Then use the input side to determine when the pump should run. You could use a water sensor for example or similar. The input side is quite smart so you can use thresholds rather than just binary levels.

Taking into account you want to control a 16amp motor with the shelly, would't it be better to attach a contactor to the shelly itself to avoid the shellly relay wearing out after many turn-ons ?

PS: I'm trying to help but, bare with me, I'm newbie to this shelly world
