    Last time I checked Tado only supported the Vaillant eBus protocol as implemented with a Vaillant VR65 controller. However newer Vaillant boilers now come with a VR66 module which speaks a slightly different eBus protocol.

    Workarounds would include -

    1. Downgrade to a VR65 module - likely will invalidate warranty and obviously an extra cost
    2. Get a VR33 module which translates eBus to OpenTherm. However this definitely invalidates the UK warranty
    3. Control the boiler in old fashioned 'call for heat' control mode
    4. And of course ask Tado if they now support the VR66 version
