Bosch Smart Home -Radiator Thermostat II - Does it work?

In this discussion: Bosch Thermostat 2 people have the Bosch Thermostat 2 working, with Zig Bee, without the Bosch bridge. I was wondering if the radiator thermostat will also work (this one, without any bridge (but with my own Zig Bee bridge). It would be my radiator thermostat of choice if this is the case. Does anyone know?

It works. See the discussion and this reply: Bosch Thermostat 2 - #25 by teekert
