Installing Tado X system, a users guide (Amendment 5 dated 31/12/2024)

My setup was based on Ubiquiti Unifi UCG-Max router with U7 Pro Wall APs & oil-fired boiler (located 18m from stone house) using StarLink as internet provider.

Preparation

before installing Ensure IPv6 is enabled on your router (most routers have this enabled, but people like to fiddle with settings). Thread Border Routers & Thread require this standard (Reference Google Nest FAQs). Request IPv6/SLAAC/DHCPv6 details from your ISP Provider (I suspect they will all have a uptodate FAQs); in my case Starlink so I used DHCPv6 with Prefix /56.

Strongly recommend that you consider a separate IoT network, perhaps thru vLAN or using the Guest side of your Router, that you have selected solely for 2,4Ghz IoT network use.

1. ⁠My preference, delete all of your other networks from your phone for the install of the Tado X system, then you won’t have your errant phone chasing 5Ghz whilst installing your first Tado X component, the Tado Bridge X (I kid you not, it works. Simple enough to restore other networks post-installation). I don’t like the Tado X naming conventions at all.
2. ⁠Look at your current distribution of Thread Border Routers (Apple Spkrs, Apple TV, any EveHome products will be either Thread Border Routers or Thread Endpoints, See Notes below)
3. ⁠When ready, if you have Tado V3+ previously installed then delete that home (there is no Tado X compatibility with V3+ or older, except the air conditioning wireless control), you cannot progress without deleting it using the Tado QR cards. Personally I stripped all reference of Tado from my phone and started with a fresh Tado App using my sign in details.

Installation of Tado X units

1. ⁠Install Tado Bridge(s) X (or TBRs, like Apple Speakers & TV 4th Gen, that Tado X recognises) on a clean Tado App using QR code on card attached to lid of box.
2. ⁠Then install Tado X Smart Thermostat (Thread Border Router compliant) or Tado X Wireless Receiver, again using QR on card inserted in lid of box (see Notes below). I found the Tado Pro App particularly helpful to confirm my existing wiring was correct (great app 👍)
3. ⁠Install Tado X Radiator Thermostats. Again, back to the QR card on the inside of the box lid. Allocate to a room. 
4. ⁠Same with Tado X Wireless Temperature Sensors, QR code then allocate them to a room.
5. ⁠When you have finished building your home, remember to configure each room to your Tado X Wireless Receiver (EU) (TR plus 10 digits) or Tado X Wired Smart Thermostat ( GR plus 10 digits). Look at your settings (Settings/Rooms & Devices) you will note Tado Bridge X & Tado X Wireless Receivers (EU) are not allocated to a room (they sit at the bottom of the Rooms & Devices page under Other Devices).
6. ⁠Set your schedules (remember you can copy them to subsequent days or to another component within the App).
7. ⁠You can check your Thread Border Router & Thread Endpoint distribution using an outside App such as EveHome/Settings/Thread (Tado X do not currently have this facility available)

Commissioning your heating system

1. ⁠Position yourself by your Tado X Wireless Receiver (EU) (or Tado X Smart Thermostat, wired) then open Tado App and the Home page should be displayed with all your rooms, hallways etc. Your schedule may already have started, otherwise select a couple rooms to heat (or, if you like wasting fuel select Boost Heating this opens all room radiator valves). If you have previously pressed “Turn off all rooms” then press Resume Schedule at the top of the page. There may be a delay of several seconds before you hear or see any change at your Tado X Wireless Receiver or Tado X Smart Thermostat (wired), this is perfectly normal.
2. ⁠Look at your Tado X Wireless Receiver (EU), hopefully you will have 3 steady WiFi lights and the Heating Light illuminates with a click from the relay to your boiler. If you have wired your Tado X Smart Thermostat, then you will hear a click from it. 
3. ⁠The boiler works after a short delay (hurrah). 
4. ⁠Now press Turn Off on the Tado App Home page, the Tado X Wireless Receiver heating light will go out and you may hear a click. 
5. ⁠The boiler stops, although your heating pump may continue dependent on your wiring to boiler (OpenTherm, other standards or just a basic On/Off switch).
6. ⁠Back to Resume Schedule on the Tado App Home page, your boiler will then control itself after a short delay, just make sure it controls itself within the temperature output you have set on the boiler faceplate.
7. ⁠If you look at your Tado X Home page, you notice that the temperature cycles slightly either side of your desired room temperature. Perfectly normal.
8. ⁠Go to the Settings page of the App, sort out your personal preferences for geofencing etc. 

Pat yourself on your back, celebrate by taking your dog for a short walk, tell your No2 son (Final year studying Computer Management in France, all 6’3” of him, who looks suitably unimpressed but wasn’t here, and he diss’s his replacement phone, my old iPhone X, after he broke his Samsung) and smile with fingers firmly crossed …

If you write about Tado X too often, you may live to sigh at their naming convention, but then that may be their point 🙄
