Underfloor heating Control on Aquara - which baterry - powered thermostat with dry contact?

Hi,
I need help selecting an Aqara thermostat for underfloor heating.

I have an Aqara M3 gateway and I’m looking for an Aqara thermostat that:

is fully compatible with it,

is battery-powered,

has a “dry contact” output – a voltage-free contact that works like a regular on/off switch that doesn’t provide its own voltage but rather closes/opens the control circuit (closed circuit = on, open = off).

I want to use this thermostat to control underfloor heating using this type of dry contact.

Does anyone:

use a specific Aqara model in this configuration?

Can they confirm that this model works with the M3 gateway and has dry contacts?

Or do they have a proven wiring diagram for connecting underfloor heating to this thermostat?

I would appreciate any suggestions and specific models that this works with.

Thanks!
