V3+ users can now request Offline Schedule

hugbilly

Yes indeed, I've thought the same.

In situation 2. the text in my screen grab suggests that the offline TRV will open and close according to temperature and local (TRV based?) schedule but its supply of hot water will need to depend on other devices in the same zone calling for heat.

In situation 1. I suppose the schedule (including calls for heat) will be preserved and, I assume manual adjustments to devices will also receive a response. But, I wonder whether the bridge will continue to function should it lose its ethernet connection to the router.

It would be useful to have some release notes giving more details of the offline feature, perhaps @Emcee would be able to help with this.

Hi, has anyone had the offline schedules yet ?

hugbilly

Yes, the feature appeared on my system about 10 days after I requested it. But of course you only know it's there if something actually goes offline!

Ajchahal

Great thanks, I put the request in a couple of days ago, I'm new to tado ! Do how did you know when it appeared ? Did your Internet go down and you then realised, or did you get a notification ?
Thanks

hugbilly

No, one of the TRVs lost contact with the bridge . . .

samd

I think I have an issue but I may have the whole thing wrong!!

My lounge has 2 rads with trvs, 1 of which is furthest from the bridge and both are controlled by a wireless temp sensor as measuring device.

The furthest trv occasionally loses contact and did so with the new 'system' and claimed to be able to continue etc etc.

Is that correct? It was not in contact with 'owt! and would not know when target temp reached etc.

@cbd20 Sorry for the late reply to your relevant question.

A V3+ heating device with the offline schedule enabled, will follow its schedule when it has lost connection to the cloud, regardless of the reason it lost this connection. So both in your 1. and your 2. case.

When a device has lost connection to the bridge, it will still open/close its valve or switch its relay based on the schedule and the measured temp, but it obviously cannot connect to the zone controller any more. So it won't actively fire the boiler, as there is no connection to the boiler. It then functions as a room without zone controller, depending on other rooms to fire the boiler.

ChrisJ

@samd My understanding (and I may be wrong) is that with the new offline feature the schedule is stored in the 'measuring' device (in this case the wireless temp sensor). So even if the TRV loses connectivity to the bridge, provided the TRV and wireless sensor are still communicating then things should work as expected.

It would be good if someone from Tado could clarify how these different variations behave … @Emcee @Rob

Rob

@ChrisJ

With V3+, all communication between tado devices happens via the bridge. So if a certain heating device loses connection to the bridge, it also loses connection to all other devices.

Honestly, I do not know what happens when a radiator thermostat goes offline in a room that has a second device as the temperature sensor. I'll try to find out.

ChrisJ

@Rob thanks, clearly I was indeed missing something. Unfortunate that the bridge is a single point of failure. I think some key questions are:

Is the schedule for a zone is pushed to all capable devices in the zone or just to the zone controller?

If the former, will any device that becomes disconnected operate autonomously?

i.e. in the scenario mentioned, do the TRVs even have the schedule? And if they do will they execute it if they become disconnected?

NeilpK

I know it states this should be activated 1-3 weeks after signing up, but I've been waiting a few weeks now and nothing has changed :o(

hugbilly

@NeilpK you'll only know if a device disconnects . . .

hugbilly

@ChrisJ said "do the TRVs even have the schedule? And if they do will they execute it if they become disconnected?"

The display a disconnected TRV shows suggests it will continue to open and close, following the schedule:

samd

@hugbilly Indeed and I agree with you, which is what I got but my point was that the off-line device will never know whether or not target temp is reached?

thefern

I know others have mentioned, but I signed up as soon as I could when this was announced and am still waiting for it to be rolled out. Can Tado give us a timeline please of activations?

hugbilly

@thefern, I never had a notification but I do now have the feature. You could try deliberately taking a TRV offline and seeing whether the app responds with a message about the offline schedule; if it does then you have it!

FFM

Couldn't Tado just send a short mail once they switch you? Or, as I understand it, eventually everyone will have it, so they could just state, "From Jan 1st, everybody has it."

It seems like something that wasn't planned but then just done anyway.

eezytiger

They do send a short email, or at least they did for me. Here's the text of it....

Hi Tim,

We would like to inform you that the offline schedule has been activated as per your request in our Forum.

Kind regards

Your tado° Support team

cbd20

Yeah I had a similar email, with subject "Feature activated". Albeit I've not actually tried it yet.

hugbilly

Happy to report my email arrived this morning,

"We would like to inform you that the offline schedule has been activated as per your request in our Forum."

It would still be good to have some release notes to accompany the feature though . . .

Mitham1

Apologies if this has been covered. I have a Wireless Temperature Sensor (part of the V3+ Starter Kit installed less than a year ago) but the device number is SU05(that is the start of the serial number, it that different from model number?) The information about offline scheduling says V3+ but with model number SU02 or SU02B. Does anyone know if my temp sensor is compatible before I fill in the form, as I would like to benefit from the offline abilities, just in case the internet goes down. Thanks.

thefern

@hugbily I tested and it's not been installed nor has eI go tan email. Any idea when this will be activated as I signed up right at the start.

samd

@thefern I have to ask the 'idiot' question but do you have any kit which qualifies?

thefern

@samd No question is silly, but yes, all 3+

samd

@Emcee Just a note to mention what occurred at my home yesterday. Background: Problems with Router which provider agreed to replace (not yet arrived) which manifests in router closing down every now and then followed by starting itself back up within a hour or so.

Last night went to bed having checked app to ensure all rooms off. At around 1 a.m. visited the loo and from there could hear boiler firing. Checked app which showed that NOTHING was calling for heat. Had to turn off boiler to prevent further waste.

It would appear to me that the multiplicity of 'Router offs and 'ons'' has, somehow, found a way to break the links set up by the new system?

Alsoff

@thefern I came here to see if anyone else was waiting for the offline schedule feature to be enabled. I added my name to the list on 18 Sept and haven't heard anything since. Hopefully Tado will get around to it soon - or perhaps they'll just roll it out to everyone.

Emcee

Hello @samd

Hard to say if this is caused by Offline Schedule or if rooted in other issues caused by faulty router. What did your heating schedule look like on the 18th when the problems started?

@Alsoff
Sent a message to the activation team. They will double check.

samd

@Emcee It now transpires that the router was not at fault, 'twas all due to local 'box'. The last room 'active' on the 18th shut down as per schedule at 2200 hrs.

Emcee

Hey @samd

Had a look at your backend. You're right, everything was 'off' on 18.10 beginning at 22:00. However, I don't see any heat requests being made until 6:00 the next morning. If it is the case that your home was heating, it's not listed in our data.

I think contacting support would be the best option here.

samd

@Emcee Thanks for your help -will do.
