new sensor, slave rad valve, unable to get them to link, app just creates an additional room

DaveCostain

I have had a failed TADO V3+ smart temperature sensor replaced by TADO.
I don’t know how to pair it with its existing TADO smart thermostatic (slave / linked) radiator valve, installed to the radiator in the same room as the replaced (new) sensor.
The original sensor was confirmed as failed by TADO helpdesk and returned / renewed under warranty.
While I was returning / awaiting a replacement sensor, I had to get the TADO agent to temporarily reactivate the smart thermostatic radiator valve to pair directly with my heating system’s Tado internet bridge instead of it being a slave to the TADO thermostatic sensor removed from the same room as the radiator.
I now have the replacement TADO smart temperature sensor, but cannot get the system to reinstate to its correct operation.
I have carried out (10+ seconds) resets to both the TADO smart temperature sensor and the TADO smart thermostatic radiator valve (including battery disconnections), then paired (3+ seconds) them to hopefully make the TADO smart thermostatic radiator valve become a slave to the TADO smart temperature sensor again, (carried out while the TADO internet bridge remained in pairing mode).
I can’t tell whether the TADO smart thermostatic (slave?) radiator valve is pairing with the new TADO smart temperature sensor, or has remained pairing directly with the TADO internet bridge.
My TADO system app now shows an additional room, (now 9 rooms instead of what should be 8 rooms).
The original room is still showing on the app with its original time / temperature settings.
A new room is also showing on the app but is set to manufacturer default settings.
Which app room is operating the TADO smart thermostatic slave radiator valve? (the original room or the new room 9?)
Which app room is operating the TADO smart temperature sensor? (the original room or the new room 9?)
How do I reinstate the heating system to operate as it did before the original TADO smart temperature sensor failed?
Please help me.

Hi cbd20. Thank you very much for your suggested remedy. It worked eventually, I was left with seven rooms, (both instances of "utility room" had disappeared), so I was able to recreate my utility room anew.

After typing in "utility room" as the new room name - the next available option ("PROCEED") at the foot of the screen, when selected, changed the cursor to a no entry sign. There is no other option but to delete the new room name, so back where I started.

I then as a last resort, tried the webpage reload button, Hey presto my "utility room" was recreated without any further input, complete with the correctly serial numbered trv and replacement sensor, also with with my original programme settings.

Thank you all for your help with getting my system fully up and running again.

@davidlyall does this procedure make sense for @DaveCostain 's situation?

1. Copy the schedules from the previous correct room to the new Room 9.
2. Delete the Trv from the old room. You'll now have 8 rooms.
3. Add the Trv into what is the recent room 9.
Make sure they are both in the same room.
4. Make the wall sensor the controller for the trv again.
If @davidlyall 's whiz brain agrees please try this idea.

I think that would work but it could be as simple as going into the device setting for the wireless temp sensor and changing it's room to be the same one as the TRV? Then, go to the room settings and ensure the WTS is the measuring device

I can't remember if that will then automatically delete the additional room as it's quite a while since I added another device to an existing room

Thanks for the replies davidlyall and policywonk. I did as David suggested, I changed the name of the replacement thermostatic sensor from the new hypothetical "room 9" assigned automatically by TADO, to its original "utility room" designation.
My app now has two "utility rooms" (they did not migrate) and after checking, find that I have the poorly located thermostatic radiator valve still controlling directly with the internet bridge, as was temporally set-up by the TADO agent while the sensors were being exchanged.
The new sensor is now controlling its own second "utility room", (also controlling directly with the internet bridge), but regulating nothing except confirming the "utility room" temperature. The trv is still not operating as a slave to the sensor, as was the original setup.
I do not know how to do what policywonk suggests, I can copy the trv programme to the sensor, but the sensor still has its own second seperate "utility room" designation.
When I tried deleting the second "utility room" (with the copied programme), only the sensor vanished from my app but the original trv is left, still controlling directly with the internet bridge.
I cannot make the trv again become a slave to the new ideally located utility room sensor.

Apologies if this has already been tried, but if you created a new room with the same name (by typing the name of the room in rather than selecting an existing room), then I think you end up with duplicating the room.

Can you not simply do the following:

In the app, click Settings - Rooms & Devices, then click the device itself. Then on that screen click Room, and then "Move to another room" and select your original Utility Room.

That should move your new device to the same virtual room as the other one. You'll then be left with an empty room you can delete? Surely?
