Bug: offline schedule clashes with wireless temp sensor?
In a room with a V3+ TRV and a wireless temperature sensor, the new offline schedule feature seems to cause continual calls for heat (fires the boiler) when a TRV goes offline.
This morning one of my TRVs went offline for a couple of hours (no clear reason, it's fine now). This TRV is in a room with a wireless temperature sensor set as the measuring device. The sensor stayed online & connected.
The temperature in the room dropped 1c below the schedule temp. The wireless temp sensor correctly called for heat, but the TRV didn't open - it remained closed and the radiator stayed cold.
In the app, the room showed as offline and highlighted the TRV as the offline device. The wireless sensor was ignored. There was no indication of using the offline schedule (I got the sign up confirmation way back in 2024).
Some of this behaviour has to be flawed?
1. With offline schedule enabled, the TRV should have opened for heat when the temp dropped below the schedule. It did not. Yes, the TRV is offline and so cannot call for heat, but the wireless sensor was still online and that WAS calling for heat as it recognised the low temp.
2. When the TRV went offline, the wireless temp sensor was ignored in the app/Tado system. I tried setting the target temperature on the wireless sensor to far below the room temperature. However this was ignored and the boiler was fired. I couldn't set a target temp on the app because the app only showed the offline TRV "screen"/icon. It seems like the offline schedule and Tado behaviour when a TRV goes offline doesn't account for the logic of an online wireless sensor in the room.
3. Alternatively If the TRV in a room with a heating sensor goes offline, the whole room should be marked offline and the wireless temp sensor ignored when calling for heat. Otherwise you get the behaviour I experienced - continual calls for heat that can never actually heat the room.
The current behaviour is the worst of all worlds. The end result was Tado calling for heat permanently until I manually switched everything off. This is pretty dangerous as the house would soon overheat.
It's also impossible to fix remotely. You have to be physically in the house to turn off the heat or the sensor. So if you're away for a few days, your boiler will be permanently on and burning gas until you get home.
The TRV came back online on its own and all is now fine.
It seems to me that fixing this behaviour will also fix one of the biggest issues with Tado V3 TRV dropping offline. If a TRV goes offline in a room with a wireless temp sensor, the offline schedule on the TRV will continue to open and close the valve, and the wireless sensor will call for heat on behalf of the offline TRV.
This is good because you can position a wireless sensor high up on a wall where it gets better signal compared to a TRV.
Thanks

It sounds like you're not using offline schedules, as you said "There was no indication of using the offline schedule". There would be an indication in the app if you were.
This behaviour is what I'd expect without offline schedules enabled i.e. TRV does nothing whilst the wireless sensor keeps calling for heat.

@davemidd Can you please explain where in the app it shows the status of offline schedules? I've supposedly had offline schedules enabled for several months and I've never seen such a notice. Thanks.0

It's either on the tile and/or when you click on the room tile. I can't remember exactly where as it was a while ago, but the wording is pretty obvious that it's using an offline schedule.

Hmmmm.... Nothing on the tile, nothing inside the tile, nothing in the schedule, nothing in the early start screen, nothing in settings, nothing anywhere.
I guess I will need to contact support.0 -
It only says it when it's actually using the offline schedule. There's nothing to say whether it's actually enabled or not.

Ah, OK. I will pull the ethernet connection and see what happens.0

@davemidd I had the email from Tado last year confirming my offline schedule activation (as per that request/feature thread).
So either you're correct and it hasn't actually been enabled for me, or the online measuring device (wireless sensor) is overriding the offline schedule for the TRV in the room.
@Emcee please can you check if offline schedules are definitely enabled for me?0 -
As discussed previously it would be really helpful if tadoº issued release notes for the new offline feature . . .

Bumping this thread. In the Offline Schedule thread, @Emcee confirmed I do indeed have offline scheduling enabled on my account.
Therefore there's definitely an issue somewhere that prevented offline scheduling, resulting in constant heating calls.
@Emcee What's the best next action here please?0 -
@cdmstr
please contact support via chat. Our bot probably won't be able to help you, but when given the option, select 'talk to a person'. Make clear you are one of the people who signed up for Offline Schedule (maybe link to the community thread that announces community members' ability to sign up). The agent will be able to investigate the issue at hand.1 -
Thank you.
Update from Tado support: although offline scheduling is enabled on my account, Support had to "push the config to my devices" as the original change to office scheduling "may not have been transmitted correctly".
I'll keep monitoring it but the take away here seems to be that the process to enable offline scheduling is "blind" - Tado support doesn't actively see whether devices have successfully enrolled into offline scheduling. So if you have offline scheduling enabled but it's not working, raise a support query.0
