Tado uses a PID control loop. P = Proporional Control - There is temperature band between setpoint and actual room temp, The I = integration time, this is variable so that the further the set point is from actual ambient the larger the valve actions, finally D = Derivative this looks at all parameters P and I then determines what a small change in valve position makes to the ambient temp, it then varies its change rate dependant on how fast the ambient reacts to valve position. So if you make a change then wait it will move. The PID loop is trying to achieve set point without overshooting. Its an excellent way to control room temperature. If the above is applied to switching then its looking to prevent switch cycling, hence boiler cycling which would cause wear and tear to boiler plus if condensing boiler did not stay on long enough to get to optimum efficiency corrosion may occur from the condensate. By making changes to the device you have there without making a corresponding change to the ambient temperature around the sensor thats why delays occur in your readings.

I was having exactly the same problem but then I realized I was changing it too often. It seems like the more often you change it, the longer it takes to switch. If you wait 10-15 minutes between changes, it always switches immediately.
It depends on where you put your thermostat and your bridge. If they are far from eachother and there are walls between them the signal is weak and the system is slow
I dont know what you are doing there but i can tell you that when i turn my Tado thermostat on and choice the Temperature i want, then after maximum 5 seconds i hear my boiler start working. So the anwere is less then 5 seconds!!!!
This test is not really valid and the delay is not a fault or even strange, it is an understandable design feature because as Deek Ireland has stated below the thermostat is trying to modulate the temperature. I very much doubt if under any normal circumstances anyone would notice yet alone care about the delay, all this "test" is doing is demonstrating how the thermostat works without trying to work out or explain why. There will always be a much more significant delay in any user interaction with the thermostat since ultimately you are only adjusting the addition of relatively low energy at the source versus the massive thermal mass of the building and the air inside it. As others have said the constant tinkering during the demonstration is probably causing the thermostat to DELIBERATELY respond slower and is a sign that it is more intelligent rather than less.
I never said there is any fault with the thermostat, and I know that THAT is the way it works.. All I was saying is that it is SLOW AF! under auto conditions, the thermostat needs to be slow, because of temperature variation (so that it would not turn off and on as it jumps between degrees) however I am commenting on the lack of intelligence when programing this device to include instant reaction to when the manual temperature is entered... If I set the thermostat to high, I expect instant reaction, not wait a minute before it finally turns on. the reason I made this video, is because the thermostat was so slow to react, that I thought it was broken. The developers could easily update their coding to add 2 states: 1st state is timed (slow to react) for auto regulation 2nd state is for instant acceptance of manual input.
"constant tinkering during the demonstration is probably causing the thermostat to DELIBERATELY respond slower" Don't make me laugh... I've set the thermostat from 25 to OFF and never tinkered with it after that... and there is no way it can read my voltmeter if you are referring to that as "tinkering"
BMH28 how is he using it incorrectly?? He isnt actually using it, he's testing it, for monitoring purposes and to demonstrate an odd/ poor design feature of tado.
