What to buy

Hi,
I am looking to purchase a Tado V3+ for my home however I am unsure what I need.
I currently have a wired danfoss control panel under the boiler in the kitchen and a small wired temperature sensor (literally just a box with no display or dial) in the hallway.
In addition I have a second wired digital display danfoss thermostat upstairs controlling the top floor.
I would like to fit the Tado in the hallway but what would replace the control panel in the kitchen?
Am I right in thinking I would need the wireless kit to replace the wired control panel in the kitchen to allow the wireless Tado thermostat to replace the temperature sensor in the hallway and then an additional wired Tado upstairs to replace the second thermostat??
