What is this?

I've never seen this before. I did a search, but I have no idea really how to word the search as…….I don't know what it is!

Its the black area, with a hand/finger?

What does it mean please?

It means that, for the time period indicated, the schedule was overridden by manual control on the relevant device.
Looks like it was set to be ‘off’. If it wasn’t you who did this, perhaps someone else adjusted a valve by accident?

@14spc

Thank you, yes, that would probably be it.

I've been trying to get a decent schedule set and failing, largely due to the odd activity of the Wired Room thermostat turning off the boiler well before the temperature has been reached, and vice versa.

At the moment I am having to manually adjust temperatures quite a lot, but often just giving up when I hear the thermostat click on, off and on again within just a few seconds.

I appreciate the insight. Thank you.

@TadoUser2 . Have you recently installed Tado? It does learn so may take a little while to settle down

Turning off the heat before the set point is reached is part of its normal behaviour. It sees the rate that the temp is rising so turns off the heat so that the remaining heat in the radiator brings the room up to the set point without overshooting too much.

It's the same if the temp is dropping but still above set point. Tado will request heat to avoid dropping too far below the set point

Let it do it's thing and see if it settles down. I used to be concerned about it but now I see that Tado is keeping my rooms at a more even temp so I don't worry about it

I guess if there is some sort of AI going on in the background, it would make sense it's learning. I wish it would learn faster!

The system has been in since June. However, I did remove the wired thermostats and re-installed the Drayton's due to the recent lag issue (the thermostats were cycling my boiler several times a second). I have since re-installed as tado sent a message saying the lag is resolved, but sadly if anything its worse with a good 60 second delay between sending a Blink command and the thermostat blinking the display. When I installed the system in June, the Blink command was near instantaneous.

I suppose the problem is now a cold snap has happened, combined with this lag, all this lovely learning stuff is possibly just confusing itself. The trouble is (for example) its taking a long while to heat the downstairs whilst we are at sub zero temperatures and I can guarantee that tado 'cleverly 'turning off the boiler when the living room is still at 17 degrees, but set at 19 degrees, is not conducive to reaching the set temperature, but as you say, I guess tado doesn't know this yet.

I sometime wish there was a switch to turn off the AI side of things.

I have asked on another post if there is still a problem with server lag, or, if not, what might be wrong and what we can check. I don't think I'm alone in still having issues.

Lag seems to be resolved now. Just checked a blink and it was 1 second until the TRV said "Hi"

Certainly seems odd that it's turning off when the temp is still 2c below the set point. What does the temp get to if you just leave it? If there's a steep increase prior to Tado turning off, it will think that will continue until it reaches the set point

Just checked my Blink command and you are right, the lag has decreased considerable to roughly as it was when I fitted (1-2 seconds). At least I now now the lag is not due to my router or other internet setting or issue.

At the time the increase was steady and slight. I have a large living room with double width doorway with no doors to the hall, basically a large open plan living room and hall, so when cold, any increase is slight, if at all. If I allowed it to do what it wanted to do (turn off) I would get one of the following:

1 - A fast drop off in temperature, and/or;

2 - The Wired Thermostat in the Hall beginning to turn on and off randomly and often in quick succession, stressing the boiler and wasting oil.

I do seem to have to spend my life micro-managing the system.

I am thinking of creating another room (Hall 2) and moving the Hall TRV to that 'room' to disconnect it from the Wired thermostat it automatically connects to. I feel like all this clever technology is too clever for my system. At the very least I think I will set the TRVs as independent and to set them to a temperature to get to by just using the schedule rather than them calling for heat.

Or just go back to a manual Drayton Room Thermostat, my Horstmann 3 channel timer/controller and just let the tado TRVs control the heat to the individual radiators when the heating is on.

Update: Blink Command back up to around 45 seconds. 😥
