Vaillant ecoFITpure combi with Salus thermostat - which TADO product?

I have a Vaillant ecoFITpure combi boiler presently controlled by a SALUS wireless thermostat in my living room. Am I correct in thinking that I need a "TADO Wireless Smart Thermostat V3+ Incl. Programmer with Hot Water Control incl. Fitting Stand" to replace my thermostat?
