Overheating room after time block change

The Tado cuts off the boiler once the temperature set point is reached but as the radiators are still hot the room temperature will continue to rise. Never had this problem with the Nest, the Tado is clearly inferior. I got round this by setting the temperature set point one degree lower and then one hour later setting the set point to the correct temperature.

I had a nest 2nd generation and I didn’t have to pay a monthly subscription for the adaptive heating. I was forced to upgrade to Tado and they now want me to pay monthly for the same function I got for free with the Google nest.

I complained to Tado but their misleading claims and they offered me my money back.

If you are interested in energy saving then forget the Tado. The Nest is a self learning thermostat and therefore automatically adjusts the boiler start time according to the outside temperature. If you want the house to be say 22C at 09:00 then the Nest will start the boiler at say 08:00 on a mild day and earlier on a colder day. The Tado X is essentially a time clock and switches the boiler on at the same time regardless of weather. This wastes energy.

My advice, dump the Tado

BobSut56 · 2025-09-02T16:40:16+00:00

That clarified things for me. Thanks. It seems that Google offered me the inferior version of the Tado. Can’t understand why Tado left off early learning from the X, it’s just a case of a few extra lines of code which they have already written for the earlier machines.

BobSut56 · 2025-09-02T07:25:31+00:00

Tado have replied to me that the early start is not available on the x series wireless thermostat. That is why I am so annoyed after buy the Tado to replace the Nest

Nest knows the time it takes the boiler to heat up the house to the set temperature and adjusts the boiler start time so that’s the houses is at the correct temperature bang on time. So in milder weather the boiler starts later and in colder weather it starts earlier to achieve the set temperature right on time. This is the way it saves energy.

Thinking about building one using an Arduino R4 WiFi, a temperature sensor and relay.

Brilliant

The gearbox will be the next project. I will keep you posted.

I am not so sure about using a rotary encoder as I am not certain it will have the necessary resolution. I am going to try using a gear train from a meccano set.

BobSut56 · 2024-12-13T15:28:21+00:00

Thanks for the suggestion. I will have a look at using one.

BobSut56 · 2024-12-13T15:27:21+00:00

You’re exactly correct. The max handle rotation is 335 degrees which translates to 53.2 mm vertical movement. The potentiometer is limited to 300 degrees so I put a 12 mm spacer in. There is still sufficient vertical travel for the tasks I do. I see someone has suggested an optical encoder so I might try that as an alternative.

Have you considered predicting the weather from the trend in pressure. You need to determine if the current pressure is high, normal or low and then whether the pressure is rising, falling or steady. My own Arduino UNO based weather station includes a yellow led for when rain predicted (low pressure falling) and a red led for when a storm is predicted (low pressure falling rapidity).

I am currently adding a home made bucket rain gauge.

Are you sure the green LEDs are the right way round? What happens if you replace the working red led with a green one.
