I also had this problem. Then I simply attached a second bridge. Without registering it with Tado. But the thermostat was then accessible.

Yes, that fits! I also had floor heating with Danfoss valves in the rooms! I replaced them with tado radiator thermostats! They work great except for one that is the furthest away from the internet bridge! I will get in touch with tado and hope they can solve the problem! Otherwise a good product!
