In my opinion, Tado has one big disadvantage. Lack of a cheap external temperature sensor or the ability to use 3’rd party sensors (e.g. via HA). My older central heating system has big pipes resulting in heating up the internal temperature sensor of the TRV very quickly and thereby shutting off the valve quickly again. To begin with I could not heat up the house at all due to this.
They have recently released a “cheaper” wireless temperature sensor at a cost of 79.99 €. I need 7 of these which would eat up whatever potential savings the smart thermostat could have given me.
I’m currently testing out this workaround but it is not ideal. At least I can heat up the house but I’m considering changing back to my old fashion thermostats.

Here you can see how the valve is pulsing. The real temperature in the room is about 19C (not shown on the graf)
